▼ Small businesses, which are defined by the US Small Business Administration as entities with less than 500 employees, suffer interruptions from diverse risks such as financial events, legal situations, or severe storms exemplified by Hurricane Sandy. Proper preparations can help lessen the length of the interruption and put employees and owners back to work. Large corporations generally have large budgets available for planning, business continuity, and disaster recovery. Small businesses must decide which risks are the most important and how best to mitigate those risks using minimal resources.
This research uses a series of surveys followed by mathematical modeling to help discover risk factors, mitigating actions, and the highest return scenarios as a basis for a low-cost business continuity/disaster recovery plan. The surveys use a Delphi study format in order to rank a base list of risks and mitigating actions and to supplement those lists with ones added by the participants. Survey results are analyzed and presented back to the group for a second round of ranking and supplementing the risk/action categories. After two rounds of surveys the data is presented to an expert panel to investigate how the risks interrelate. Quantifying the interrelationships is the basis for the Cross Impact Analysis model that is able to show the relative impact of one event upon another. Once the impacts are known, a series of high valued scenarios are developed using Interpretive Structural Modeling. These high valued scenarios can be used by the small businesses as a basis for a business continuity/disaster recovery plan.

▼ A constantly evolving regulatory environment, increasing market pressure to improve operations, and rapidly changing business conditions are creating the need for ongoing assurance that organizational risks are continually and adequately mitigated. Enterprises are perpetually exposed to fraud, poor decision making and/or other inefficiencies that can lead to significant financial loss and/or increased levels of operating risk. Increasingly, Information Systems are being harnessed to reinvent the risk management process. One promising
technology is Continuous Auditing, which seeks to transform the audit process from periodic reviews of a few transactions to a continuous review of all transactions. However, the highly integrated, rapidly changing and hypercompetitive business environment of many corporations spawns numerous Enterprise Risks that have been excluded from standard risk management processes. An extension of Continuous Auditing is Continuous Monitoring, which is used by management to continually review business processes for unexpected deviations. Using a Delphi, the feasibility and desirability of applying Continuous Monitoring to different Enterprise Risks is studied. This study uncovers a significant relationship between the perceived business value of Continuous Monitoring and years of experience in Risk Management and Auditing, determines that all key architectural components for a Continuous Monitoring system are known, and indicates that Continuous Monitoring may be better suited for monitoring computer crime than monitoring strategic risks such as the loss of a competitive position.

▼ The Dynamic Hypermedia Engine (DHE) enhances analytical applications by adding relationships, semantics and other metadata to the application's output and user interface. DHE also provides additional hypermedia navigational, structural and annotation functionality. These features allow application developers and users to add guided tours, personal links and sharable annotations, among other features, into applications. DHE runs as a middleware between the application user interface and its business logic and processes, in a n-tier architecture, supporting the extra functionalities without altering the original systems by means of application wrappers.
DHE automatically generates links at run-time for each of those elements having relationships and metadata. Such elements are previously identified using a Relation Navigation Analysis. DHE also constructs more sophisticated navigation techniques not often found on the Web on top of these links. The metadata, links, navigation and annotation features supplement the application's primary functionality.
This research identifies element types, or "classes", in the application displays. A "mapping rule" encodes each relationship found between two elements of interest at the "class level". When the user selects a particular element, DHE instantiates the commands included in the rules with the actual instance selected and sends them to the appropriate destination system, which then dynamically generates the resulting <i>virtual</i> (i.e. not previously stored) page. DHE executes concurrently with these applications, providing automated link generation and other hypermedia functionality. DHE uses the extensible Markup Language (XMQ -and related World Wide Web Consortium (W3C) sets of XML recommendations, like Xlink, XML Schema, and RDF -to encode the semantic information required for the operation of the extra hypermedia features, and for the transmission of messages between the engine modules and applications.
DHE is the only approach we know that provides automated linking and metadata services in a generic manner, based on the application semantics, without altering the applications. DHE will also work with non-Web systems.
The results of this work could also be extended to other research areas, such as link ranking and filtering, automatic link generation as the result of a search query, metadata collection and support, virtual document management, hypermedia functionality on the Web, adaptive and collaborative hypermedia, web engineering, and the semantic Web.

▼ This dissertation researchdesigned, implemented, and evaluated a Web-based Dynamic Voting Toolfor small group decision-making in a collaborative environment.
In this dissertation, theliterature on voting tools in current GDSS research is presented. Variousvoting theories and methods are analyzed, and the advantages and weaknessesare compared, so as to gain a better understanding of how to apply thesedifferent voting methods to diverse decision-making situations. A briefoverview of scaling theories is also given, with an emphasis on Thurstone'sLaw.
The basic features of someweb-based voting tool implementations are reviewed along with a discussionof the pros and cons of Intemet voting. A discussion of Human DynamicVoting (HDV) follows; HDV allows multiple voting and continuous feedbackin a group process. The Dynamic Voting Tool designed and developed bythe author (i.e., Zheng Li) integrated multiple scaling and voting methods,and supported dynamic voting. Its features, user feedback, and futureimprovements are further discussed.
A controlled experiment wasconducted to evaluate the effects of the Dynamic Voting Tool (alongwith the List Gathering Tool by Yuanqiong Wang) interacting with smallgroup process. The design and procedures of the experiment, and thedata analysis results extracted from 187 student subjects from
New JerseyInstitute of
Technology are reported. While the System Survey yieldedvery positive feedback on the voting tool, the hypotheses tested bythe Post-Questionnaire and expert judgments showed no major positivesignificant results. This was probably due to the complexity of thetask and procedures, lack of motivation of the subjects, bad timing,insufficient training, and uneven distribution of subjects, etc.
Several field studies usingthe Social Decision Support System (SDSS) Toolkit (List Gathering Tool+ Dynamic Voting Tool) are presented. The SDSS system worked well whenthe subjects were motivated. The field studies show that the toolkitcan be used in course evaluations, or other practical applications.
Finally, it is suggestedthat future research can focus on improving the voting tool with truedynamic features, exploring more issues on SDSS systems design and experimentation,and exploring the relationship of voting and GSS.

▼ This research focuses on how to build a "list" structure to combine individual items of information into some sort of structure that converts the individual items of information into a structure of knowledge relative to the problem. Software was designed to provide relationships among and comparisons of the contributions in a "list" structure, so that individual members of a group process will be able to understand the contributions of information made by the group as a whole.
A List Gathering Tool was designed and implemented, which is one component in a Web-based Social Decision Support System (SDSS) Toolkit. Then, a two-by-two factorial design (list tool support vs. no list tool support, and voting tool support vs. no voting tool support, respectively) controlled experiment and several field studies were carried out to assess the effects of this List Gathering Tool in a group problem solving process.
Overall, the evaluation results are encouraging. The utilization of the List Gathering Tool or the SDSS Toolkit does tend to improve the ability to discover valid alternatives. An additional set of field trials illustrated how the SDSS Toolkit can be utilized in a collaborative learning environment to improve teaching and students' learning experience. This system will also work for very practical applications in large group settings.

▼ The exploration into the underlying psychosocial links of pair programming. a
new and unorthodox programming paradigm in which two programmers share one keyboard and monitor during real-time programming sessions, is undertaken. These complex psychosocial relationships, along with cognitive process exchanges, ultimately mold the programming output as well as determine the level of communication, satisfaction. confidence and compatibility. Laying the framework for this research, a through review of traditional and contemporary paradigms with a special focus on their limitations and a list of current software development problems are presented. Next, a detailed summary of pair programming and related agile software paradigms, such as extreme programming, which lists pair programming as one of its twelve principles, is given. From earlier pair programming studies, a number of programming benefits have been unveiled and these are listed and discussed. However, a lack of formal studies pertaining to the psychosocial aspects of pair programming exists. Given this void, a field survey is administered to a group of professional programmers and a resulting list of influencing factors on pair programming emerges. From the list, the most popular factor, personality, and two other factors, communication and gender, have been selected in order to study their impact on pair programming product outcome and the level of communication, satisfaction, confidence and compatibility. An experiment focusing on these factors is designed and implemented. From the experimental findings, the personality of the two partners in pair programming is found to have a significant impact on the pair programming output. Also, it is discovered that same gender pairs exhibited an unusually high level of communication, satisfaction and compatibility between each other, especially among female-female pairs. A detailed statistical experiment result based on research hypotheses is reported.

▼ Although multimodal computer input is believed to have advantages over unimodal input, little has been done to understand how to design a multimodal input mechanism to facilitate visually impaired users' information access.
This research investigates sighted and visually impaired users' multimodal interaction choices when given an interaction grammar that supports speech and touch input modalities. It investigates whether task type, working memory load, or prevalence of errors in a given modality impact a user's choice. Theories in human memory and attention are used to explain the users' speech and touch input coordination.
Among the abundant findings from this research, the following are the most important in guiding system design: (1) Multimodal input is likely to be used when it is available. (2) Users select input modalities based on the type of task undertaken. Users prefer touch input for navigation operations, but speech input for non-navigation operations. (3) When errors occur, users prefer to stay in the failing modality, instead of switching to another modality for error correction. (4) Despite the common multimodal usage patterns, there is still a high degree of individual differences in modality choices.
Additional findings include: (I) Modality switching becomes more prevalent when lower working memory and attentional resources are required for the performance of other concurrent tasks. (2) Higher error rates increases modality switching but only under duress. (3) Training order affects modality usage. Teaching a modality first versus second increases the use of this modality in users' task performance.
In addition to discovering multimodal interaction patterns above, this research contributes to the field of human computer interaction design by: (1) presenting a design of an eyes-free multimodal information browser, (2) presenting a Wizard of Oz method for working with visually impaired users in order to observe their multimodal interaction.
The overall contribution of this work is that of one of the early investigations into how speech and touch might be combined into a non-visual multimodal system that can effectively be used for eyes-free tasks.

▼ SMS text-messaging is an interoperable communication vehicle known to be dependable for mass media alert notifications in crisis management. SMS text-messaging also offers potential as one viable two-way communication alternative for field responders in crisis response. Both continuously changing mobile information communication technologies and the importance of precise information exchange constitute a need for communication protocol training and practice. This study introduces a
technology-mediated training technique based on speech act and communicative action theories. These theories are used to inform the design of a baseline measure for task performance improvement and to suggest a model to predict communication readiness. Because this research bridges two fields - information systems and communication - it provides a model for full construct-representation of text-based interaction in a
technology-mediated environment. The proposed model is validated through a web-based training application with
50 participants who have different crisis response backgrounds, including emergency management practitioners, first responders, public safety volunteers, community volunteers, community citizens, and students over the age of 18. Each group encompasses diverse technological skill and usage levels.
The web-based training application developed in the present study features plain language training so that a clear understanding of user behavior, response, and training would emerge. The training and crisis scenario are rendered through multimedia recordings and designed to measure task response, based on the 160 character per SMS text-message exchange limit. The mixed-methods design begins with a crisis scenario, followed by pre-training measures, three repeated training measures, and concludes with post-training measures. A total of six tasks are introduced (3 pre-training and 3 post-training) in which each participant interfaces with the web-based training application through a high-speed Internet connection. Task response level results show promise for this exploratory research and contribute to a
new discourse mode that extends to mobile
technology penetration. Future research will focus on refinement of the model's task performance measures and will seek to introduce additional situation-based scenarios and mixed-modes of communication. During this next research phase, the objective is to incorporate the model into mobile device usage and operationalize the model in authentic crisis management contexts. If successful in extended field simulation, the model may have the potential to ensure effective mobile information communication within the context of crisis.

▼ When organizations collaborate they often do so using partially distributed teams (PDTs). In a Partially Distributed Team there exist at least two distinct sub-groups. In addition, at least one of the sub-groups has two or more members that are geographically co-located. Co-located members can meet face to face; chat in the hallway; have lunch together; and otherwise socialize with one another. On the other hand, remote members must rely on
technology to communicate and work together. This distinct characteristic of partially distributed teams makes them especially susceptible to the In-Group / Out Group dynamic (Huang and Ocker, 2006). This dynamic manifests itself when members of a co-located sub-group treat each other with preference or exhibit a more favorable attitude towards each other than they do towards their remote colleagues. We refer to such behaviors as 'Us-vs.-Them' and categorize their occurrences.
After examining why and how Us-vs.-Them occurs in Partially Distributed Teams, we attempt to understand under which conditions it exists and persists, as well as its relationship to effectiveness. We examine conditions of
technology, team configuration, employee motivation, and organizational policies that may reduce Us-vs.-Them, and formulate a model for reduction of Us-vs.-Them and increase of effectiveness. We test our model using a survey instrument distributed to 238 industry professionals.
We found support among participant comments confirming the existence of Us-vs.-Them in partially distributed teams and its importance. We also found a strong relationship between Us-vs.-Them and effectiveness. High Us-vs.-Them showed a very high correlation to reduced effectiveness. We found support for the value of
technology uniformity between sub-groups as well as
technology reliability, for decreasing Us-vs.-Them. And we showed that just as in traditional teams, regular meetings are helpful in partially distributed teams.
Although we discuss informally implemented policies that proved to be valuable in partially distributed teams, we discovered that the more formal policies are the more effective type. Other important findings include: Us-vs.-Them is more prevalent in international teams as well as in teams that are composed of two sub-groups only; and when motivated by flexible schedule, work creativity, and challenging work, participants had higher perceived effectiveness ratings.
Most prior PDT research was conducted using student teams or case studies of one or two industry teams. A contribution of this dissertation research is collection and analysis of a large sample of industry data. Another important contribution is the isolation of Us-vs.-Them as a dependent variable. Understanding under which conditions it exists is important so that managers can identify it and prevent it from escalating.

▼ When evaluating participation within an Asynchronous Learning Network (ALN), current best practices include counting messages and reviewing participant surveys. To understand the impact of more advanced dynamic measurement tools for use within an ALN, a web-based tool, known as iPET (the integrated Participation Evaluation Tool), was created. iPET, which leverages Social Network Analysis and Information Visualization techniques, was then evaluated via an empirical study. This research demonstrates that using a tool such as iPET increases participation within an ALN without increasing facilitator workload. Due to the fact that active online discussion is a key factor in the success of an ALN, this research demonstrates that dynamic measuring tools for online participation can help ensure a positive outcome within an online learning environment.

▼ The improvement of Internet
technology has motivated distributed work groups to collaborate without meeting face to face. Although asynchronous meetings through Web-based group communications systems enable groups dispersed temporarily and geographically to collaborate more flexibly, parallel and non-linear communication among dispersed members also challenge effective and efficient group coordination. Moreover, the Web-based asynchronous meeting is distinguished not only from the face-to-face meeting but also from the synchronous computer-supported meeting in terms of coordination process. However, previous asynchronous group communications or virtual team research focused more on the comparison of this
new type of meeting with the face-to-face meeting. Not many research efforts have been exerted to improve the productivity of this
new form of meeting and find ways to overcome its disadvantages. Facilitation was proved effective to enhance the productivity of synchronous meetings. However the effect of structured discussion through facilitation was not clear in asynchronous meeting settings even though facilitation is a common practice in asynchronous group communication systems.
This study examined the effect of a facilitated structure in improving the productivity of asynchronous decision-making groups. Delphi was chosen as the facilitated structure because it has been widely used as the paper-and-pencil-based structure to facilitate dispersed experts in collecting their opinions. In this study a computer-based Delphi structure was implemented through asynchronous Computer-Mediated Communication. A 2X2 controlled experiment was conducted to investigate the effect of Delphi structure on the effectiveness of small-sized (5-6 members) and medium-sized (10-12 members) asynchronous computer-supported groups. The formal facilitation using Delphi structure was effective to improve the productivity of asynchronous groups in generating more ideas. On the contrary, informal leadership by group coordinators seems to have played a more important role in producing better reports. In terms of per person ideas, small-sized groups were more productive, even though medium-sized groups produced more total ideas than small-sized groups. The superiority of Delphi groups and small-sized groups is related to their higher equality of participation. This result suggests that in asynchronous meetings, equal participation of group members in discussion is important in improving idea generation productivity while in synchronous meetings, the process loss of production blocking plays a crucial role.

▼ Data Definition Languages (DDLs) have been created and used to represent data in programming languages and in database dictionaries. This representation includes descriptions in the form of data fields and relations in the form of a hierarchy, with the common exception of relational databases where relations are flat. Network computing created an environment that enables relatively easy and inexpensive exchange of data. What followed was the creation of
new DDLs claiming better support for automatic data integration. It is uncertain from the literature if any real progress has been made toward achieving an ideal state or limit condition of automatic data integration. This research asserts that difficulties in accomplishing integration are indicative of socio-cultural systems in general and are caused by some measurable attributes common in DDLs. This research’s main contributions are: (1) a theory of data integration requirements to fully support automatic data integration from autonomous heterogeneous data sources; (2) the identification of measurable related abstract attributes (Variety, Tension, and Entropy); (3) the development of tools to measure them. The research uses a multi-theoretic lens to define and articulate these attributes and their measurements. The proposed theory is founded on the Law of Requisite Variety, Information Theory, Complex Adaptive Systems (CAS) theory, Sowa’s Meaning Preservation framework and Zipf distributions of words and meanings. Using the theory, the attributes, and their measures, this research proposes a framework for objectively evaluating the suitability of any data definition language with respect to degrees of automatic data integration.
This research uses thirteen data structures constructed with various DDLs from the 1960's to date. No DDL examined (and therefore no DDL similar to those examined) is designed to satisfy the law of requisite variety. No DDL examined is designed to support CAS evolutionary processes that could result in fully automated integration of heterogeneous data sources. There is no significant difference in measures of Variety, Tension, and Entropy among DDLs investigated in this research. A direction to overcome the common limitations discovered in this research is suggested and tested by proposing GlossoMote, a theoretical mathematically sound description language that satisfies the data integration theory requirements. The DDL, named GlossoMote, is not merely a
new syntax, it is a drastic departure from existing DDL constructs. The feasibility of the approach is demonstrated with a small scale experiment and evaluated using the proposed assessment framework and other means. The promising results require additional research to evaluate GlossoMote’s approach commercial use potential.

▼ Document representation (indexing) techniques are dominated by variants of the term-frequency analysis approach, based on the assumption that the more occurrences a term has throughout a document the more important the term is in that document. Inherent drawbacks associated with this approach include: poor index quality, high document representation size and the word mismatch problem. To tackle these drawbacks, a document representation improvement method called the Relevance Feedback Accumulation (RFA) algorithm is presented. The algorithm provides a mechanism to continuously accumulate relevance assessments over time and across users. It also provides a document representation modification function, or document representation learning function that gradually improves the quality of the document representations. To improve document representations, the learning function uses a data mining measure called "support" for analyzing the accumulated relevance feedback.
Evaluation is done by comparing the RFA algorithm to other four algorithms. The four measures used for evaluation are (a) average number of index terms per document; (b) the quality of the document representations assessed by human judges; (c) retrieval effectiveness; and (d) the quality of the document representation learning function. The evaluation results show that (1) the algorithm is able to substantially reduce the document representations size while maintaining retrieval effectiveness parameters; (2) the algorithm provides a smooth and steady document representation learning function; and (3) the algorithm improves the quality of the document representations. The RFA algorithm's approach is consistent with efficiency considerations that hold in real information retrieval systems.
The major contribution made by this research is the design and implementation of a novel, simple, efficient, and scalable technique for document representation improvement.

▼ On the Web, there are limited ways of finding people sharing similar interests or background with a given person. The current methods, such as using regular search engines, are either ineffective or time consuming. In this work, a
new approach for searching people sharing similar interests from the Web, called People-Search, is presented. Given a person, to find similar people from the Web, there are two major research issues: person representation and matching persons. In this study, a person representation method which uses a person's website to represent this person's interest and background is proposed. The design of matching process takes person representation into consideration to allow the same representation to be used when composing the query, which is also a personal website. Based on this person representation method, the main proposed algorithm integrates textual content and hyperlink information of all the pages belonging to a personal website to represent a person and match persons. Other algorithms, based on different combinations of content, inlink, and outlink information of an entire personal website or only the main page, are also explored and compared to the main proposed algorithm. Two kinds of evaluations were conducted. In the automatic evaluation, precision, recall, F and Kruskal-Goodman F measures were used to compare these algorithms. In the human evaluation, the effectiveness of the main proposed algorithm and two other important ones were evaluated by human subjects. Results from both evaluations show that the People-Search algorithm integrating content and link information of all pages belonging to a personal website outperformed all other algorithms in finding similar people from the Web.

▼ Inter-organizational collaboration is becoming more common. When organizations collaborate they often do so in partially distributed teams (PDTs). A PDT is a hybrid team that has at least one collocated subteam and at least two subteams that are geographically distributed and communicate primarily through electronic media. While PDTs share many characteristics with both traditionally collocated and fully distributed teams, they also have unique characteristics and issues.
This dissertation reports on a field study of PDTs conducted over two semesters with student participants, This research was conducted as part of a larger series of studies investigating PDTs, In these studies, participants were formed into PDTs of two collocated subteams each. The task was to produce requirements for an emergency response information system for a specified country. Study 1 varied leadership configuration but held distance constant. Study 2 varied both leadership configuration and distance.
Although distance was to be measured as cultural, geographic, and temporal distance, multicollinearity issues arose and cultural distance was dropped from the analysis. Distance was measured as time zone differences which, because the subteams in a team had east-west geographic distance, captured the geographic distance as well.
Data collection was through surveys and personal reflections, Personal reflections are open ended survey questions for which the subjects reflected on their experiences the previous week in a PDT. This dissertation reports on qualitative and quantitative analyses of Study 1 data and quantitative analysis of Study 2 data, In addition to bivariate analyses of the survey data conducted separately for each study, multivariate analysis using Partial Least Squares (PLS) was performed on the combined Study 1 and Study 2 data.
Factor analysis resulted in the identification of three types of trust: Expertise Trust, Personal Trust, and Process Trust, Trust was measured in the first personal reflection (after one week) and in the post survey at the end of the four week project, Early trust has the dimensions of Expertise Trust, Personal Trust, and Process Trust while longer term trust is comprised of Personal Trust and Process Trust.
The results partially support the proposed research model. Strong support was found for the proposition that leadership roles identified by Quinn (1988) and examined in fully virtual and traditionally collocated teams are enacted in PDTs as well, Results suggest that leadership configuration influences leader role enactments. Trust was found to be important to team outcomes and influenced by media used and distance. Leadership role enactments were associated with perceptions of leader effectiveness, perceptions of performance, and satisfaction. Results suggest that leader effectiveness is associated with trust, perceptions of performance, and satisfaction. That is, trust, leadership configuration, distance, and leader role enactments all play important roles in…

▼ In the fields of Emergency Management and Business Continuity Planning, scenarios are a widely used tool for planning, training and knowledge sharing purposes. The ability to create and discuss emergency scenarios in virtual teams can lead to many potential applications, such as discussing emergency scenarios by world-wide experts, conducting on-line exercises, and creating Communities of Practices. Existing scenario creation systems, like NxMsel provided by FEMA, allow distributed groups to create scenarios together. However, collaborative support in these systems is generally limited.
This dissertation explores an innovative solution to provide various types of collaboration support around a knowledge structure and uses this approach to build a collaborative scenario creation system called Collario (Collaborative Scenario). Following the Design Scenario paradigm, this research goes through four iterations to evolve Collario into a working prototype. Several evaluation methods, like system demonstration, protocol analysis and field study, have been employed to evaluate the design effects and get user feedback, The results show that Collario is useful to support creation and discussion of emergency scenarios in virtual teams and to share knowledge and experiences among geographically distributed emergency professionals and researchers. It is also found that Collario is not hard to learn and use.

▼ Existing techniques for emergency preparedness planning and training fail or lack the ability to convey training on a broad scale and timely fashion. Skill sets that are required for planning, mitigation, response and recovery issues are lost through information overload or failure to identify other channels in which to convey the information. In order to resolve some of the issues with currently existing methods such as tabletop training exercises (TTX), instructional video learning and full-scale exercises we can turn to virtual environments.
In a virtual environment teams can interact with their surroundings from the comfort of the office without having to incur the costs associated with traveling to various exercises. Additionally, a virtual city could allow for teams to develop a shared awareness, attempt to utilize and reinforce skill sets, while at the same time providing a safe, realistic, and adaptive gaming environment.

The techniques are based on the assumption that the human brain is a rigid body and will assume different positions during different scanning periods. One technique uses three fiducial markers, while the other two uses eigenvectors of the inertia matrix of the Neuro-Image, to compute the three angles (pitch, yaw and roll) needed to register the test Neuro-Image to the reference Neuro-Image. A rigid body transformation is computed and applied to the test Neuro-Image such that it results aligned to the reference Neuro-Image. These techniques were tested by applying known rigid body transformations to given Neuro-Images. The transformations were retrieved automatically on the basis of unit vectors or eigenvectors. The results show that the precision of two techniques is dependent on the axial resolution of the Neuro-Images and for one of them also on the imaging modality, while the precision of one technique is also dependent on the interpolation. Such methods can be applied to any Neuro-Imaging modality and have been tested for both fMRI and MRI.

▼ The goal of text mining is to find interesting and non-trivial patterns or knowledge from unstructured documents. Both objective and subjective measures have been proposed in the literature to evaluate the interestingness of discovered patterns. However, objective measures alone are insufficient because such measures do not consider knowledge and interests of the users. Subjective measures require explicit input of user expectations which is difficult or even impossible to obtain in text mining environments.
This study proposes a user-oriented text-mining framework and applies it to the problem of discovering novel association rules from documents. The developed system, uMining, consists of two major components: a background knowledge developer and a novel association rules miner. The background knowledge developer learns a user's background knowledge by extracting keywords from documents already known to the user (background documents) and developing a concept hierarchy to organize popular keywords. The novel association rule miner discovers association rules among noun phrases extracted from relevant documents (target documents) and compares the rules with the background knowledge to predict the rule novelty to the particular user (useroriented novelty).
The user-oriented novelty measure is defined as the semantic distance between the antecedent and the consequent of a rule in the background knowledge. It consists of two components: occurrence distance and connection distance. The former considers the co-occurrences of two keywords in the background documents: the more the shorter the distance. The latter considers the common connections of with others in the concept hierarchy. It is defined as the length of the connecting the two keywords in the concept hierarchy: the longer the path, distance.
The user-oriented novelty measure is evaluated from two perspectives: novelty prediction accuracy and usefulness indication power. The results show that the useroriented novelty measure outperforms the WordNet novelty measure and the compared objective measures in term of predicting novel rules and identifying useful rules.
