▼ The problem of ontology matching is crucial due to decentralized development and publication ofontological data. An approach proposed towards matching the
ontologies is by inferring a match betweentwo
ontologies as a maximum likelihood problem, and solves it using the technique of expectationmaximization (EM). The structural and lexical similarities between the graphs are identified in thisapproach, and a many-one map between the concept nodes is produced. Due to highly intensivecomputations during the EM it becomes extremely difficult to work with larger
ontologies. In order toscale the method to large
ontologies, we identify the computational bottlenecks and modify thegeneralized EM by using a memory bounded partitioning scheme. The algorithm is improved byimplementing two additional similarity measures: edge labels and instance similarity. We also present atool for visual ontology alignment called Optima that has an interactive user interface and usesgeneralized EM for matching. The tool is supported by an intuitive user interface that facilitates thevisualization and analysis of
ontologies in N3, RDF and OWL and the alignment results. We providecomparative experimental results in support of our method on two well-known ontology alignmentbenchmarks and discuss their implications.Keywords:

▼ In any semantic solution, data could be annotated
using ontologies. Ontologies are shared specifications and
therefore the same ontologies can be used for the annotation of
multiple data sources, like web pages, eXtensible Markup Language
documents, relational databases and so on. Their shared
terminologies enable a certain degree of interoperability between
the data sources using the same ontologies. To enable such
interoperation, mediation is required between the ontologies.
Ontology mediation includes operations such as, ontology mapping,
alignment, matching, merging and integration. Algorithms for
matching and merging of ontologies using directed graphs are
developed and the theoretical aspects are dealt with. The fitness
of the matched graph is elaborated as an evaluation metric. The
research study also demonstrates a new approach of ontology
management using Ontology Abstract Machines. Ontology matching,
merging using Ontology Abstract Machine is illustrated using health
care domain. The research work has proposed a framework for
ontology matching and merging. The framework is validated by an
innovative approach for developing Ontology based Question Bank
System. Although other approaches have been discussed in the
literature, the approach presented in this work is based on domain
ontologies. It identifies important concepts and generates multiple
choice questions about these concepts along with the distracters.
Each question bank consists of sets of test items each of which
consists of a question or stem. An ontological system integrated
with an educational platform can support teachers in building
effective question bank system and students are tested using
generated questions. To this end the researcher has proposed an
ontological approach to semantically enrich question bank
generation. In particular the association of semantics to the
question bank system can greatly improve their organization and
management, both for students and teachers.

▼ Due to the growing complexity, sophistication, and interconnectedness of present day engineered products and services, the use of
ontologies in engineering design is becoming more widespread. An ontology provides a standardized way of describing concepts in a domain of interest and the relationships between these concepts to better understand the domain as a whole. The benefits of using
ontologies vary greatly depending on where and how they are implemented in the engineering space, however the field of complex systems and services can benefit from the level of specification that
ontologies provide by reducing the ad hoc nature of some design activities. This paper presents the techniques involved in developing and using two different
ontologies both in the aerospace and education domain, each yielding different results. Working with NASA Ames Research Center, this research has improved their customer requirement formulation process. In the education sector, the use of an ontology has helped better understand the parallels between design education disciplines and engineering design curricula. The
ontologies explained in this paper were created using unique methodologies, Excel spreadsheets, Python programing, and Protégé Owl, an open source ontology editor. This thesis can be used as a stepping-stone for other engineers who want to achieve a more organized, effective, and productive engineering space.

▼ With the tremendous growth of the Web, a broad spectrum of accommodation information is to be found on the Internet. In order to adequately support information users in collecting and sharing information online, it is important to create an effective information integration solution, and to provide integrated access to the vast numbers of online information sources. In addition to the problem of distributed information sources, information users also need to cope with the heterogeneous nature of the online information sources, where individual information sources are stored and presented following their own structures and formats. In this thesis, we explore some of the challenges in the field of information integration, and propose solutions to some of the arising challenges. We focus on the utilization of ontology for integrating heterogeneous, structured and semi-structured information sources, where instance level data are stored and presented according to meta-data level schemas. In particular, we looked at XML-based data that is stored according to XML schemas.
In a first step towards a large-scale information integration solution, we propose a semantic integration framework. The proposed framework solves the problem of information integration on three levels: the data level, process level and architecture level. On the data level, we leverage the benefit of ontology, and use ontology as a mediator for enabling semantic interoperability among heterogeneous data sources. On the process level, we alter the process of information integration, and propose a three step integration process named as the publish-combine-use mechanism. The primary goal is to distribute the efforts of collecting and integrating information sources to various types of end users. In the proposed approach, information providers have more control over their own data sources, as data sources are able to join and leave the information sharing network according to their own preferences. On the architecture level, we combine the flexibility offered by the emerging distributed P2P approach with the query processing capability provided by the centralized approach. The joint architecture is similar to the structure of the online accommodation industry.
This thesis also demonstrates the practical applicability of the proposed semantic integration framework by implementing a prototype system. The prototype system named the "accommodation hub" is specifically developed for integrating online accommodation information in the large, distributed, heterogeneous online environment. The proposed semantic integration solution and the implemented prototype system are evaluated to provide a measure of the system performance and usage. Results show that the proposed solution delivers better performance with respect to some of the evaluation criteria than some related approaches in information integration.

▼ This paper presents a project whose main objective is to explore the Ontological-based development
of Domain Specific Languages (DSL), more precisely, of their underlying Grammar.
After reviewing the basic concepts characterizing
Ontologies and Domain-Specific Languages, we
introduce a tool, OWL2Gra, that takes profit of the knowledge described by the ontology and automatically
generates a grammar for a DSL that allows to discourse about the domain described by that
ontology.
This approach represents a rigorous method to create, in a secure and effective way, a grammar for
a new specialized language restricted to a concrete domain. The usual process of creating a grammar
from the scratch is, as every creative action, difficult, slow and error prone; so this proposal is, from a
Grammar Engineering point of view, of uttermost importance.
After the grammar generation phase, the Grammar Engineer can manipulate it to add syntactic
sugar to improve the final language quality or even to add semantic actions.
The OWL2Gra project is composed of three engines. The main one is OWL2DSL, the component
that converts an OWL ontology into an attribute grammar. The two additional modules are Onto2OWL
and Ddesc2OWL. The former, Onto2OWL, converts
ontologies written in OntoDL (a light-weight DSL
to describe
ontologies) into standard OWL XML that can be loaded into the well known Proteg´ e sys- ´
tem to future editing; the later, Ddesc2OWL, converts domain instances written in the DSL generated
by OWL2DSL into the initial OWL ontology.
Ddesc2OWL plays an important role because it allows for the population of the original ontology
with concept and relation instances extracted from the new language concrete sentences this allow a
faster ontology population.

▼ The Web Ontology Language, OWL, is the latest standard in logic based ontology languages. It is built upon the foundations of highly expressive Description Logics, which are fragments of First Order Logic. These logical foundations mean that it is possible to compute what is entailed by an OWL ontology. The reasons for entailments can range from fairly simple localised reasons through to highly non-obvious reasons. In both cases, without tool support that provides explanations for entailments, it can be very difficult or impossible to understand why an entailment holds. In the OWL world, justifications, which are minimal entailing subsets of ontologies, have emerged as the dominant form of explanation. This thesis investigates justification based explanation techniques. The core of the thesis is devoted to defining and analysing Laconic and Precise Justifications. These are fine-grained justifications whose axioms do not contain any superfluous parts. Optimised algorithms for computing these justifications are presented, and an extensive empirical investigation shows that these algorithms perform well on state of the art, large and expressive bio-medical ontologies. The investigation also highlights the prevalence of superfluity in real ontologies, along with the related phenomena of justification masking. The practicality of computing Laconic Justifications coupled with the prevalence of non-laconic justifications in the wild indicates that Laconic and Precise justifications are likely to be useful in practice. The work presented in this thesis should be of interest to researchers in the area of knowledge representation and reasoning, and developers of reasoners and ontology editors, who wish to incorporate explanation generation techniques into their systems.

▼ Ontologies are descriptions of the knowledge about a domain of interest encoded in computer processable languages, e.g., Description Logics, which are decidable fragments of First Order Logic. The main aim of ontologies is to define unambiguous vocabularies to facilitate knowledge sharing and integration. A critical issue with ontologies consists of their increasing complexity. To address this problem several notions of modularity have been recently proposed. Modularity notions can help in two ways: 1) If we know what sub-part of the ontology we want to work with, obtaining the appropriate module will allow us to work with that sub-part in a principled way; 2) a notion of module might induce a modular structure which allows users to explore the entire ontology in a sensible manner (perhaps finding appropriate sub-parts to work on). However, the most popular notion – locality based modules – while excelling at modular extraction have thus far resisted attempts to induce a modular structure. Indeed, due to their nature, locality based modules tend to occur in unfeasible numbers in ontologies. We tackle this problem by identifying basic building blocks of modules as sets of axioms which 'cling together', that is, sets of axiom such that if any element appears in a module, then all the rest due. This notion of an 'atom'' proves key to defining a useful family of locality based modular structures, the (Labelled) Atomic Decompositions ((L)ADs). In this thesis, we define (L)AD and explore its properties. We show that ADs are efficiently computable and, with appropraite labellings, provide a reasonably terse representation of the entire set of locality based modules. From ADs, we are able to distinguish so-called "genuine" modules, i.e., modules that cannot be decomposed further as the union of two or more modules. Finally, we explore several of the applications to which (L)ADs have been applied including module extraction, ontology comprehension, and modular reasoning.

Module-based classification of OWL ontologies.

▼ Classification is a core reasoning service provided
by most OWL reasoners. Classification in general is hard - up to
2NExptime for SROIQ(D), the Description Logic which is underpinning
the Web Ontology Language (OWL). While it has been shown that
classification is practical for a wide range of inputs, there are
still ontologies for which classification takes an unreasonable
amount of time for purposes such as ontology engineering (frequent
classifications after updates). A natural optimisation strategy is
divide and conquer, that is, to decompose the ontology into subsets
which are hopefully easier to classify and whose classifications
can be combined into a complete classification of the whole
ontology. Unfortunately, an arbitrary subset may not be
self-contained, i.e. it might be missing information that is needed
to determine entailments over its signature. Moreover, such a
subset can be potentially harder to classify than the whole
ontology. In order to mitigate those problems, classification
preserving decompositions (CPDs) must be designed with care that
they support complete classification which is, in practice, more
efficient than monolithic classification. Locality-based modules
are subsets of an ontology that provide certain guarantees with
respect to the entities (concepts, roles) in its signature - in
particular, modules are self-contained. In this thesis we explore
the use of syntactic locality-based modules for underpinning
classification-preserving decompositions. In particular, we
empirically explore their potential to avoid subsumption tests and
reduce subsumption test hardness and weigh those benefits against
detrimental effects such as overhead (for example the time it takes
to compute the decomposition) and redundancy (a consequence of
potentially overlapping chunks in the decomposition). The main
contributions of this thesis are an in-depth empirical
characterisation of these effects, an extensible framework for
observing CPDs in action up until a granularity of individual
subsumption tests, a large, public corpus of observations and its
analysis and insights on experimental methodologies around OWL
reasoning.

▼ Assessment is a well understood educational topic
with a really long history and a wealth of literature. Given this
level of understanding of the topic, educational practitioners are
able to differentiate, for example, between valid and invalid
assessments. Despite the fact that we can test for the validity of
an assessment, knowing how to systematically generate a valid
assessment is still challenging and needs to be understood. In this
thesis we introduce a similarity-based method to generate a
specific type of questions, namely multiple choice questions, and
control their difficulty. This form of questions is widely used
especially in contexts where automatic grading is a necessity. The
generation of MCQs is more challenging than generating open-ended
questions due to the fact that their construction includes the
generation of a set of answers. These answers need to be all
plausible, otherwise the validity of the question can be
questionable. Our proposed generation method is applicable to both
manual and automatic gener- ation. We show how to implement it by
utilising ontologies for which we also develop similarity measures.
Those measures are simply functions which compute the similarity,
i.e., degree of resemblance, between two concepts based on how they
are described in a given ontology. We show that it is possible to
control the difficulty of an MCQ by varying the degree of
similarity between its answers. The thesis and its contributions
can be summarised in a few points. Firstly, we provide literature
reviews for the two main pillars of the thesis, namely question
generation and similarity measures. Secondly, we propose a method
to automatically generate MCQs from ontologies and control their
difficulty. Thirdly, we introduce a new family of similarity
measures. Fourthly, we provide a protocol to evaluate a set of
automatically generated assessment questions. The evaluation takes
into account experts’ reviews and students’ performance. Finally,
we introduce an automatic approach which makes it possible to
evaluate a large number of assessment questions by simulating a
student trying to answer the questions.

▼ En dépit des efforts destinés à accroitre la maturité de la profession dans le domaine de la gestion de projet, le taux d’échec des projets d’affaires (par opposition aux projets techniques) reste élevé. On s’est aperçu que les standards actuels en matière de gestion de projet ne prenaient pas en compte les contraintes liées au contexte d’exécution des projets, et que de ce fait, la gestion de projets d’affaires n’avait pas été étudiée en profondeur. L’objectif de ce travail de recherche transdisciplinaire est donc d’abord d’obtenir une meilleure compréhension du sujet en essayant de comprendre pourquoi l’échec d’un projet d’affaires est considéré comme un échec du point de vue de l’organisation, puis de formaliser la connaissance acquise dans un format qui permette par la suite de l’enrichir et de l’appliquer. En nous appuyant sur le modèle des systèmes ouverts, trois études de cas ont été conduites, avec pour objectif d’étudier l’effet modérateur des différents types de structures des organisations et des systèmes d’information pour la gestion de projet sur la relation causale entre la compétence en gestion de projet et le succès des projets d’affaires. Il résulte de ce travail que le succès des projets d’affaires devrait être mesuré en termes de réalisation des objectifs du projet mais aussi de l’organisation. Ce travail a également permis d’identifier les composants essentiels de la gestion de projets d’affaires : (1) “Compétences de base pour la gestion de projet ”; (2) “Gestion intégrée de programme” et (3) “Système d’information intégré pour la gestion de projet”. Dans les trois études de cas, il apparait également de manière déterminante que les facteurs d’ordre organisationnel ont un impact significatif sur la réussite du projet. Une théorie est proposée, qui postule qu’un projet d’affaires a de grandes chances d’échouer s’il n’est pas géré comme une partie intégrante de l’entreprise, en le traitant comme une opération courante au sein de l’entreprise. Cela signifie que la manière dont les projets d’affaires sont gérés aujourd’hui devrait être revue. Le rôle de l’informatique dans l’assistance à la gestion de ces projets devrait également être revu. Et il faudrait sans doute aussi faire une plus grande différence entre les projets d’affaires et les projets « traditionnels » plus techniques. D’autre part, la formalisation de la connaissance acquise au cours de ces études de cas a été effectuée en développant un modèle de domaine à l’aide du langage de modélisation UML. Et l’approche de modélisation du domaine a été élaborée en modifiant l’étape de conceptualisation dans le processus traditionnel d’ingénierie d’ontologie. En prenant comme point de départ le cadre théorique qui prend en compte l’essentiel des composants de la gestion de projets d’affaires, le modèle a été construit en quatre étapes : (1) définition de la portée du travail en développant chaque composant à partir des normes en vigueur ; (2) intégration de ces développements en réutilisant les travaux réalisés et proposés par d’autres chercheurs…

▼ This thesis highlights the recent developments in Requirements Engineering for Software Product Line Engineering, with a focus on the use of ontology in interactive Requirements Elicitation and the existing techniques of ontology operations. Recent research done in Requirements Elicitation has been towards using
ontologies as a modeling basis for gathering requirements. A new algorithm has been developed to allow
ontologies to be combined at run-time when gathering the requirements of software clients. By harnessing knowledge in other
ontologies, a more refined set of requirements can be generated. A scenario illustrating the use of ontology combination towards acquiring requirements for mobile platforms is also provided. The proposed method further enhances the capability of interactive software customization, thus helping to make Software Product Line Engineering a new practice in software development.

La composition des services Web définit une nouvelle forme d'interopérabilité entre les systèmes d'information et les applications distribuées et hétérogènes. Cette nouvelle forme offre des perspectives prometteuses en termes de collaboration et de coopération pour différentes organisations commerciales et industrielles. Cependant, les services Web participant dans une composition, sont implémentés par différents fournisseurs qui ont des contextes différents impliquant des interprétations différentes, ce qui augmente les hétérogénéités entre les services, notamment, les hétérogénéités sémantiques de données échangées entre les services qui peuvent générer des dysfonctionnements ou des résultats imprévisibles pendant l'exécution de la composition. Dans ce mémoire, nous nous intéressons au problème d'interopérabilité sémantique. Nous traitons, particulièrement, le problème d'hétérogénéité sémantique et contextuelle de données échangées entre les services Web, participant et le service Web composite (la composition elle-même). Notre travail s'inscrit autour d'une solution de médiation de données basée sur le contexte afin de détecter et résoudre automatiquement les conflits sémantiques et contextuels de données échangées dans une composition. Dans notre proposition, nous allons se baser sur les ontologies afin de représenter les contextes locaux et de décrire la sémantique globale des données qui circulent dans une composition

La composition des services Web définit une nouvelle forme d'interopérabilité entre les systèmes d'information et les applications distribuées et hétérogènes. Cette nouvelle forme offre des perspectives prometteuses en termes de collaboration et de coopération pour différentes organisations commerciales et industrielles. Cependant, les services Web participant dans une composition, sont implémentés par différents fournisseurs qui ont des contextes différents impliquant des interprétations différentes, ce qui augmente les hétérogénéités entre les services, notamment, les hétérogénéités sémantiques de données échangées entre les services qui peuvent générer des dysfonctionnements ou des résultats imprévisibles pendant l'exécution de la composition. Dans ce mémoire, nous nous intéressons au problème d'interopérabilité sémantique. Nous traitons, particulièrement, le problème d'hétérogénéité sémantique et contextuelle de données échangées entre les services Web, participant et le service Web composite (la composition elle-même). Notre travail s'inscrit autour d'une solution de médiation de données basée sur le contexte afin de détecter et résoudre automatiquement les conflits sémantiques et contextuels de données échangées dans une composition. Dans notre proposition, nous allons se baser sur les ontologies afin de représenter les contextes locaux et de décrire la sémantique globale des données qui circulent dans une composition

▼ Currently, one of the key issues facing applications and integration of Geographic Information Systems is the lack of interoperability among various systems due to the diversity of data representations. The semantics of geographic information have been identified to provide a conceptual model in which common understanding of the information can be achieved to support interoperability. Ontologies with capability of conceptualise information domains can be used as the tool for expressing the semantics. This paper describes how to utilise ontologies to capture the semantics of geographic information and further presents a way to represent and store spatial data in a knowledge base within an ontology. By representing geographic information in an ontology, the reasoning capability supplied by the knowledge representation can be explored to provide new methods for utilising and analysing spatial information.
Interoperability is a key concern in the field of Geographic Information Sciences for the sharing of geographic information and the integration of geospatial processes. Web service technology is a mainstream approach to distribute GIS functionality in the Web environment and provide syntactic interoperability for different processes, and ontologies have been considered as a significant technique to achieve interoperability on the semantic level. This paper describes how the mainstream Web technologies can be applied for interoperability of geospatial processes and implements the methodology with a use case of specific processes.

▼ Com o advento da Internet, novas tecnologias de Geoprocessamento têm sido criadas para tratar, trocar, disponibilizar e acessar informações e dados espaciais como as Infraestruturas de Dados Espaciais, os Geobrowsers e os Serviços de Informações Geográficas. O número de aplicações que lida com atributos espaciais não somente cresceu como também se diversificou, no entanto problemas de interoperabilidade semântica ainda limitam a evolução nessa área. Ontologias formalizam o conhecimento necessário para organizar e permitir o uso de dados de diferentes fontes, pois são modelos de referência robustos devido à sua expressividade e capacidade de serem compartilhados pela internet. Nesta tese, ontologias foram desenvolvidas para aumentar a interoperabilidade semântica em sistemas de apoio à logística humanitária que utilizam serviços de informações geográficas. A aplicação de logística humanitária estudada foi a operação de bancos de alimentos. O conhecimento relativo aos processos logísticos, problemas logísticos de bancos de alimentos e serviços de informações geográficas úteis para os métodos de solução desses problemas foram formalizados em uma rede de ontologias. O número de serviços de informações geográficas disponíveis ainda é pequeno, mas a composição de serviços de informações geográficas em cadeias, formando novos serviços, abre uma perspectiva para que operações espaciais, não fiquem mais restritas às soluções proprietárias e possam ser melhor exploradas. As ontologias propostas neste trabalho podem ser usadas como base para o desenvolvimento de sistemas em que serviços de informações geográficas podem ser acoplados, na medida em que forem sendo disponibilizados.
With the advent of Internet, new technologies from GIS field have been created to access and exchange spatial data and information, such as Spatial Data Infrastructures, Geobrowsers and Geographic Information Services. The number of applications dealing with spatial attributes is growing and is also diversifying. However semantic interoperability problems still limit progress in this area. Ontologies formalize the knowledge necessary to organize and allow the use of data from different sources due to its expressiveness and ability to be shared over the Internet. In this thesis, ontologies have been developed to increase the semantic interoperability of humanitarian logistics support systems that use geographic information services. The application of humanitarian logistics operation studied was the food banks operation. The knowledge on logistics processes, logistics problems of food banks and geographic information services useful for the methods for solving these problems have been formalized into a network of ontologies. The number of geographical information services available is still small, but the composition of geographic information services in chains, creating new services, opens a perspective for new methods of spatial operations, which are not limited to proprietary solutions form GIS softwares available in the market. The ontologies…

▼ Στην παρούσα εργασία αναφερόμαστε στις δυνατότητες αξιοποίησης των Οντολογιών στην Εκπαίδευση. Το αντικείμενο είναι ο σχεδιασμός συστήματος Εκπαίδευσης στη Στατιστική ,το οποίο θα χρησιμοποιεί οντολογίες για την αναπαράσταση του γνωστικού αντικειμένου και του εκπαιδευτικού περιεχομένου. Η ανάπτυξη των οντολογιών θα γίνει με το περιβάλλον Protégé.
Στο πρώτο κεφάλαιο θα κάνουμε μια επισκόπηση στην έννοια της Οντολογίας. Θα αναφερθούμε στον ορισμό και στις δυνατότητες της, στα είδη των οντολογιών, στην κατηγοριοποιησή τους και στις γλώσσες αναπαράστασης οντολογιών. Θα γίνει μια συνοπτική παρουσίαση των εργαλείων και των μεθοδολογιών ανάπτυξης των οντολογιών.
Στο δεύτερο κεφάλαιο αναλύεται η χρήση των οντολογιών στην Εκπαίδευση και συγκεκριμένα οι μαθησιακές οντολογιές που μπορούν να χρησιμοποιηθούν για την ανάπτυξη ευφυών εκπαιδευτικών πληροφοριακών συστημάτων. Ο χρήστης μαθησιακού υλικού μπορεί να αναζητήσει μαθησιακό υλικό με το περιεχόμενο, τη μορφή και τη δομή του. Για τα συστήματα ηλεκτρονικής μάθησης οι διάφορες πτυχές των τμημάτων του μαθησιακού υλικού περιγράφονται απο τα μεταδεδομένα.
Στο τρίτο κεφάλαιο θα δούμε τον ορισμό των μαθησιακών στόχων, ποιοί είναι οι μαθησιακοί στόχοι στην εκπαίδευση, ποιοί είναι οι διδακτικοί στόχοι και ποιά είναι τα σημαντικά τους στοιχεία. Στο τέλος του κεφαλαίου αυτού θα παρουσιαστεί η ταξινομιά Bloom, η οργάνωση και η κατηγοριοποίηση των δεξιοτήτων της σκέψης και των στόχων .
Στο τέταρτο κεφάλαιο θα αναλύσουμε το πρότυπο μεταδεδομένων Scorm, το οποίο αποτελεί σήμερα τη σημαντικότερη πρωτοβουλία που αναπτύσσεται στον τομέα των προτύπων του e-Learning.
Στο πέμπτο κεφάλαιο θα αναλύσουμε την έννοια της Στατιστικής που θα αποτελέσει το γνωστικό μας αντικείμενο για την δημιουργία της συνδυαστικής οντολογίας μας.
Στο έκτο κεφάλαιο θα παρουσιάσουμε την μελέτη που πραγματοποιήθηκε στις θεματικές ενότητες της Πληροφορικής του Ελληνικού Ανοικτού Πανεπιστημίου.
Στο έβδομο κεφάλαιο θα περιγράψουμε τον τρόπο κατασκευής των οντολογιών μας, Για την κάθε οντολογία που θα κατασκευάσουμε θα παρουσιαστεί ο λόγος ανάπτυξης της και το πεδίο ενδιαφέροντος, θα καθοριστούν οι ερωτήσεις επάρκειας για την κάθε οντολογία, θα γίνει λεπτομερής περιγραφή των κλάσεων, των ιδιοτήτων των κλάσεων και των στιγμιότυπων της κάθε οντολογίας, θα περιγραφεί λεπτομερός το περιβάλλον ανάπτυξης, η γλώσσα αναπαράστασης των οντολογιών και στο τέλος θα γίνει τεχνική και ποιοτική αξιολόγηση της οντολογίας.
Η δοκιμή των Οντολογιών μας στο περιβάλλον Protégé έδειξε πως το μοντέλο διαχείρισης μαθησιακών αντικειμένων και μαθησιακών στόχων που δημιουργήσαμε λειτουργεί αποτελεσματικά σε σχέση με τους στόχους που είχαμε θέσει αφου μας δίνει τη δυνατότητα να ορίσουμε με τυπικό τρόπο βασικές συνιστώσες της μαθησιακής διαδικασίας.

▼ Management of large amounts of complex and
multi-dimensional scientific data, residing in different data
sources has become a huge challenge in the scientific domain.
Researchers require technologies to facilitate understanding of the
data, in particular the ability to effectively organize complex
data, perform efficient analysis, share and discover relevant data
and facilitate searches over large data sets. Existing systems and
approaches have tried to resolve these problems individually and
have been successful to some extent. But there is a lack of an
end-to-end solution that suits the dynamically emerging needs of
the scientific community. This thesis is an attempt to fill this
gap by presenting the work done in each of these areas and by
proposing an end-to-end framework that follows the meta-data driven
approach to resolve these issues in an integrated manner. Also, the
framework demonstrates that the concept of
ontologies and
folksonomies can be leveraged to manage scientific data. To provide
validation to the framework, the component architecture and
functionality of its simple yet powerful implementation, MetaDB is
described.

▼ Ontologies play key roles in many applications today. Therefore, whether using a newly-specified ontology or an existing ontology for use in its target application, it is important to determine the suitability of an ontology to the application at hand. This need is addressed by carrying out ontology evaluation, which determines qualities of an ontology using methodologies, criteria or measures. However, for addressing the ontology requirements from a given application, it is necessary to determine what the appropriate set of criteria and measures are. In this thesis, we propose a Requirements-Oriented Methodology for Evaluating Ontologies (ROMEO). ROMEO outlines a methodology for determining appropriate methods for ontology evaluation that incorporates a suite of existing ontology evaluation criteria and measures. ROMEO helps ontology engineers to determine relevant ontology evaluation measures for a given set of ontology requirements by linking these requirements to existing ontology evaluation measures through a set of questions. There are three main parts to ROMEO. First, ontology requirements are elicited from a given application and form the basis for an appropriate evaluation of ontologies. Second, appropriate questions are mapped to each ontology requirement. Third, relevant ontology evaluation measures are mapped to each of those questions. From the ontology requirements of an application, ROMEO is used to determine appropriate methods for ontology evaluation by mapping applicable questions to the requirements and mapping those questions to appropriate measures. In this thesis, we perform the ROMEO methodology to obtain appropriate ontology evaluation methods for ontology-driven applications through case studies of Lonely Planet and Wikipedia. Since the mappings determined by ROMEO are dependent on the analysis of the ontology engineer, the validation of these mappings is needed. As such, in addition to proposing the ROMEO methodology, a method for the empirical validation of ROMEO mappings is proposed in this thesis. We report on two empirical validation experiments that are carried out in controlled environments to examine the performance of the ontologies over a set of tasks. These tasks vary and are used to compare the performance of a set of ontologies in the respective experimental environment. The ontologies used vary on a specific ontology quality or measure being examined. Empirical validation experiments are conducted for two mappings between questions and their associated measures, which are drawn from case studies of Lonely Planet and Wikipedia. These validation experiments focus on mappings between questions and their measures. Furthermore, as these mappings are application-independent, they may be reusable in subsequent applications of the ROMEO methodology. Using a ROMEO mapping from the Lonely Planet case study, we validate a mapping of a coverage question to the F-measure. The validation experiment carried out for this mapping was inconclusive, thus requiring further analysis. Using a…

▼ O reuso de software é uma área de pesquisa da engenharia de software que tem
por objetivo prover melhorias na produtividade e qualidade da aplicação através
da redução do esforço. Trata-se de reutilizar artefatos existentes, ao invés de
construí-los do zero a fim de criar novas aplicações. Porém, para obter os
benefícios inerentes ao reuso, alguns obstáculos devem ser superados como, por
exemplo, a questão da busca e recuperação de componentes. Em geral, há uma
lacuna entre a formulação do problema, na mente do desenvolvedor e a
recuperação do mesmo no repositório, o que resulta em resultados irrelevantes
diminuindo as chances de reuso. Dessa maneira, mecanismos que auxiliem na
formulação das consultas e que contribuam para uma recuperação mais
próxima à necessidade do desenvolvedor, são bastante oportunos para
solucionar os problemas apresentados.
Nesse contexto, este trabalho propõe a extensão de uma ferramenta de
busca por palavra-chave através de uma camada semântica que tem por objetivo
principal aumentar a precisão da busca e, conseqüentemente, aumentar as
chances de reuso do componente procurado. A criação da camada semântica é
representada basicamente por dois componentes principais: um para auxiliar o
usuário na formulação da consulta, através do uso de uma ontologia de
domínio, e outro para tornar a recuperação mais eficiente, através de uma
indexação semântica dos componentes no repositório

▼ This dissertation explores the fundamental conceptual
underpinnings of folksonomies and their potential contribution to
semantic interoperability among our sociotechnical systems.
Currently, formal ontologies attempt to provide semantic
interoperability for our computational technologies, but they are
problematic in that they simultaneously overspecify and
decontextualize information, which to be meaningful must be
adaptive in context. Folksonomies, on the other hand, are less well
defined; they don’t have any formal structure and are able to
evolve as the lexicon of a community adapts to newly developed
understandings among its members. Researchers have made various
efforts, with limited success, at coupling ontologies and
folksonomies to derive some sort of semantic interoperability. The
difficulty with this coupling reveals a multifaceted tension
between 1) structured ontologies and unstructured folksonomies, 2)
lexicality, syntax and semantics, 3) social and cultural dimensions
of tags, and 4) emergence and reification. In this dissertation I
propose an original model, the Emergent Culture Model (ECM), which
allows for structuring the relationships between the social and
cultural dimensions of tags as a means of discerning the emergent
semantics of folksonomies. The ECM posits cognitive schemas as a
mediating mechanism between the social and cultural dimensions of
tags. Schemas, when shared as cultural schemas, illustrate the
importance of identity and how we employ multiple identities in the
creation of semantics within folksonomies. The mediating role of
schemas leads to a reconceptualization of folksonomies as semantic
networks that serve as ready-to-hand entry points into networks of
cultural schemas. These schemas help us navigate the complex
cultural landscapes that comprise our human conceptual ontologies
and provide a flexible structure through which we share these
landscapes in a social context. The ECM is used to illustrate that
current folksonomy research focuses solely on the social dimensions
of tags and reifies the link between signifier and signified (i.e.,
between tag and resource) based on the traditional semiotic model.
Current research fails to consider the cultural dimensions of tags,
which are necessary for discerning their emergent semantics. The
structure of the ECM enables a discussion of tags using a
Heideggerian phenomenological frame to explore tags-as-equipment,
tags-as-patterns, and tagging-as-practice. When tags function as
equipment, they exist as part of a semiotic relationship as a sign,
which Heidegger says, “functions both as this definite equipment
and as something indicative of the ontological structure of
readiness-to-hand, of referential totalities.” In exploring
tags-as-patterns, I contend that a tag is ontic, not ontological,
and only fulfill their ontic function as part of the
phenomenological care-structure of Dasein, where the Heideggerian
ideas of thrownness, mood, solicitude and falling hold sway. The
interactions between equipment and care-structure reflects the…

▼ Thanks to the affordability of DNA sequencing, hundreds of thousands of individuals with rare disorders are undergoing whole-genome sequencing in an effort to reveal novel disease aetiologies, increase our understanding of biological processes and improve patient care. However, the power to discover the genetic causes of many unexplained rare diseases is hindered by a paucity of cases with a shared molecular aetiology. This thesis presents research into statistical and computational methods for determining the genetic causes of rare diseases. Methods described herein treat important aspects of the nature of rare diseases, including genetic and phenotypic heterogeneity, phenotypes involving multiple organ systems, Mendelian modes of inheritance and the incorporation of complex prior information such as model organism phenotypes and evolutionary conservation. The complex nature of rare disease phenotypes and the need to aggregate patient data across many centres has led to the adoption of the Human Phenotype Ontology (HPO) as a means of coding patient phenotypes. The HPO provides a standardised vocabulary and captures relationships between disease features. I developed a suite of software packages dubbed 'ontologyX' in order to simplify analysis and visualisation of such ontologically encoded data, and enable them to be incorporated into complex analysis methods. An important aspect of the analysis of ontological data is quantifying the semantic similarity between ontologically annotated entities, which is implemented in the ontologyX software. We employed this functionality in a phenotypic similarity regression framework, 'SimReg', which models the relationship between ontologically encoded patient phenotypes of individuals and rare variation in a given genomic locus. It does so by evaluating support for a model under which the probability that a person carries rare alleles in a locus depends on the similarity between the person's ontologically encoded phenotype and a latent characteristic phenotype which can be inferred from data. A probability of association is computed by comparison of the two models, allowing prioritisation of candidate loci for involvement in disease with respect to a heterogeneous collection of disease phenotypes. SimReg includes a sophisticated treatment of HPO-coded phenotypic data but dichotomises the genetic data at a locus. Therefore, we developed an additional method, 'BeviMed', standing for Bayesian Evaluation of Variant Involvement in Mendelian Disease, which evaluates the evidence of association between allele configurations across rare variants within a genomic locus and a case/control label. It is capable of inferring the probability of association, and conditional on association, the probability of each mode of inheritance and probability of involvement of each variant. Inference is performed through a Bayesian comparison of multiple models: under a baseline model disease risk is independent of allele configuration at the given rare variant sites and under an alternate model disease…

▼ Τα φαινόμενα απάτης τείνουν να κυριαρχήσουν τις τελευταίες δεκαετίες σε κάθε τομέα. Ένας τομέας που πλήττεται ιδιαίτερα στις μέρες μας είναι αυτός της υγειονομικής περίθαλψης γενικά και ειδικά της συνταγογράφησης των φαρμάκων. Οι υγειονομικές υπηρεσίες είναι ιδιαίτερα τρωτές στην απάτη και την κατάχρηση. Τόσο οι φορείς κοινωνικής ασφάλισης, όσο και οι ιδιωτικές ασφαλιστικές εταιρείες χάνουν όλο και περισσότερα χρήματα κάθε χρόνο, λόγω ψευδών αιτιών αποζημιώσεων.
Το αντικείμενο της παρούσας διατριβής είναι ο σχεδιασμός και η ανάπτυξη μιας μεθοδολογίας ανίχνευσης και πρόληψης της απάτης, που θα μπορεί να εφαρμοστεί στις επιχειρησιακές διεργασίες των υπηρεσιών υγειονομικής περίθαλψης και θα εξασφαλίζει την ελαχιστοποίηση της απώλειας των σχετικών κεφαλαίων. Η ίδια θα είναι σε θέση να ανιχνεύει τα ύποπτα προς απάτη περιστατικά, εξασφαλίζοντας έτσι την ποιότητα και την συνέπεια των παρεχόμενων υπηρεσιών.
Fraud phenomena tend to dominate the last decades. A sector that is particularly affected in our days is that of healthcare domain in general and specifically prescriptions reimbursement. Healthcare services are particularly vulnerable in fraud and abuse. Not only institutions of social insurance, but also private companies lose more money each year, because of false causes of compensations.
This thesis intends to illustrate the planning and development of a fraud detection methodology, which is accompanied and supported by a generic fraud ontological framework. This methodology will be able to detect erroneous or suspicious records, ensuring thus the quality and the consequence of provided services.

▼ Hybrid knowledge bases are knowledge bases that combine
ontologies with non-monotonic
rules, allowing to join the best of both open world
ontologies and close world rules.
Ontologies
shape a good mechanism to share knowledge on theWeb that can be understood
by both humans and machines, on the other hand rules can be used, e.g., to encode legal
laws or to do a mapping between sources of information.
Taking into account the dynamics present today on the Web, it is important for these
hybrid knowledge bases to capture all these dynamics and thus adapt themselves. To
achieve that, it is necessary to create mechanisms capable of monitoring the information
flow present on theWeb. Up to today, there are no such mechanisms that allow for monitoring
events and performing modifications of hybrid knowledge bases autonomously.
The goal of this thesis is then to create a system that combine these hybrid knowledge
bases with reactive rules, aiming to monitor events and perform actions over a knowledge
base. To achieve this goal, a reactive system for the SemanticWeb is be developed in
a logic-programming based approach accompanied with a language for heterogeneous
rule base evolution having as its basis RIF Production Rule Dialect, which is a standard
for exchanging rules over theWeb.

▼ Nowadays, the industry is very demanding in terms of customized high quality products at
lower costs. Furthermore, the customers intention of having the product as soon as possible,
and companies having the restriction of time, which in this case is a crucial variable, also
increases the nal product cost. For this reason, it becomes unacceptable the development of
solutions based on centralized implementations, which do not provide robustness, exibility
and recon gurability. Therefore, the implementation of multi-agent based solutions ful l the
described requirements leading to a more exible, robust and agile system.
This work presents the development of an important issue concerning the cooperation
between the distributed agents, since one of them only has a partial view of the system.
In this way the
ontologies are crucial to guarantee a common structure of the knowledge
exchanged among the agents.
The objective of this work is the development of an ontology integrating process and
quality levels to be used to represent the knowledge exchanged in a multi-agent system solution
for a production line producing washing machines. Consequently, the agents exchanging
shared knowledge will support better and more accurate decisions.
The contribution of this work comprises the implementation of a multi-agent system, the
appropriate ontology formulation as well as its implementation, which makes the integration
of an industrial production line more versatile and more customized. Naturally, with this
project, it is created a recon gurable and highly interoperable system. Hoje em dia, a indústria é muito exigente em termos de produtos personalizados de alta
qualidade a custos baixos. Além disso, a intenção dos clientes é ter o produto logo que
possível, assim as empresas têm uma limitação de tempo, que neste caso é uma variável
importante, também aumenta o custo do produto nal.
Por esta razão, torna-se inaceitável o desenvolvimento de soluções baseadas em implementa
ções centralizadas, que não proporcionam a exibilidade, robustez e recon gurabilidade.
Portanto, a implementação de soluções baseadas em multi-agente cumprem os requisitos
descritos levando a um sistema mais exível, robusto e ágil.
Este trabalho representa o desenvolvimento de uma questão importante relativa à coopera
ção entre os agentes distribuídos, uma vez que apenas um deles tem uma visão parcial
do sistema. Desta forma, as ontologias são cruciais para garantir uma estrutura comum de
conhecimento trocadas entre os agentes.
O objectivo deste trabalho é o desenvolvimento de uma ontologia da integração de processos
e qualidade a serem utilizados para representar o conhecimento trocado em uma solução
de sistema multi-agente para uma linha de produção de máquinas de lavar. Consequentemente,
os agentes trocam conhecimento compartilhado que irão suportar decisões melhores
e mais precisas.
A contribuição deste trabalho consiste na implementação de um sistema multi-agente, a
adequada formulação da ontologia, bem como a sua implementação, o que torna a integração…

▼ Techniques for the industrial implementation of emerging semantic technologies are presented in this research. Every new design, project, and procedure within a company generates a considerable amount of new information and important knowledge. Furthermore, a tremendous amount of legacy knowledge already exists within companies in electronic and non-electronic formats. All of this generated knowledge results in the need for tools and techniques to represent, structure, and reuse this knowledge. Researchers have spent considerable time and effort developing semantic knowledge management systems, with anticipation that these tools will address these knowledge management needs. However, little has been done to implement these systems within an industrial setting.
In this thesis, we identify five main requirements for the development of an industry-ready, semantic knowledge management system, and we discuss how each of these requirements can be methodically addressed. The five requirements include the incorporation of legacy information, the ease of new knowledge management software adoption, the robustness of the software to support multiple file types and allow for the sharing of information across platforms, the security of the stored information, and the ease of use of the user interface. In collaboration with Raytheon, a defense and aerospace systems company, we developed and demonstrated a novel approach for the successful adoption of semantic abilities by a commercial company. Salient features of this work include a new tool, the e-Design
MemoExtractor Software Tool, custom designed to mine and capture company information, a Raytheon-specific ontology extension to the e-Design Framework, and a novel semantic environment in the form of a customized semantic media wiki
SMW+. The advantages of this approach and the associated research issues are discussed in the context of the industrial case study with Raytheon.

▼ Thanks to the affordability of DNA sequencing, hundreds of thousands of individuals with rare disorders are undergoing whole-genome sequencing in an effort to reveal novel disease aetiologies, increase our understanding of biological processes and improve patient care.
However, the power to discover the genetic causes of many unexplained rare diseases is hindered by a paucity of cases with a shared molecular aetiology. This thesis presents research into statistical and computational methods for determining the genetic causes of rare diseases.
Methods described herein treat important aspects of the nature of rare diseases, including genetic and phenotypic heterogeneity, phenotypes involving multiple organ systems, Mendelian modes of inheritance and the incorporation of complex prior information such as model organism phenotypes and evolutionary conservation.
The complex nature of rare disease phenotypes and the need to aggregate patient data across many centres has led to the adoption of the Human Phenotype Ontology (HPO) as a means of coding patient phenotypes. The HPO provides a standardised vocabulary and captures relationships between disease features. I developed a suite of software packages dubbed 'ontologyX' in order to simplify analysis and visualisation of such ontologically encoded data, and enable them to be incorporated into complex analysis methods. An important aspect of the analysis of ontological data is quantifying the semantic similarity between ontologically annotated entities, which is implemented in the ontologyX software. We employed this functionality in a phenotypic similarity regression framework, 'SimReg', which models the relationship between ontologically encoded patient phenotypes of individuals and rare variation in a given genomic locus. It does so by evaluating support for a model under which the probability that a person carries rare alleles in a locus depends on the similarity between the person's ontologically encoded phenotype and a latent characteristic phenotype which can be inferred from data.
A probability of association is computed by comparison of the two models, allowing prioritisation of candidate loci for involvement in disease with respect to a heterogeneous collection of disease phenotypes.
SimReg includes a sophisticated treatment of HPO-coded phenotypic data but dichotomises the genetic data at a locus. Therefore, we developed an additional method, 'BeviMed', standing for Bayesian Evaluation of Variant Involvement in Mendelian Disease, which evaluates the evidence of association between allele configurations across rare variants within a genomic locus and a case/control label. It is capable of inferring the probability of association, and conditional on association, the probability of each mode of inheritance and probability of involvement of each variant. Inference is performed through a Bayesian comparison of multiple models: under a baseline model disease risk is independent of allele configuration at the given rare variant sites and under an alternate model…
