1. Persson, Erik. Virtual Assistants and Their Performance In Professional Environments.

Degree: Electrical Engineering and Computer Science (EECS), 2020, KTH

Contributors from the mid 20th century up to now have developed and refined virtual assistants, taking the technology from a set of rules to assistants driven by Artificial Intelligence. Today, virtual assistants can provide value in organisation and support a sustainable society by conducting basic and repetitive tasks, and help reduce inequalities caused by biased advisors on sensitive topics. Despite its prosperity, current research somewhat lack focus on the evaluation of virtual assistants in industrial applications. The purpose of this paper is to evaluate virtual assistants from a technical, economical and organisational perspective, in order to understand their performance and value in an industrial environment. This has been done in collaboration with IBM and a client company which prefers to remain anonymous in this report. In this company, two IBM Watson Assistants are under development; one for the IT Service Desk, and one for the Ethics & Compliance department. To cover all aspects of the virtual assistants’ performance, quantitative and qualitative methods were used by conducting user testings and surveys. In this process, discussions have been conducted with IBM experts and employees of the firm for which the practical implementation has been studied, to gain a general and specific understanding from different perspectives. From this paper, the following can be concluded. First, technological performance can be described using quantitative metrics such as coverage, confidence, precision and helpfulness, and should be complemented using qualitative measures such as user satisfaction and perceived user understanding. Second, specific technological performance is relative and the technical limitations as well as it’s maturity should be used as a complement to the evaluation of the assistants. Third, identified organisational benefits include: • reduced time-to-resolution, • reduced handling time, • all-hour-support, • scalability and • user understanding Conclusions specific for the use cases show that an assistant implemented in a narrower use case, that is the Ethics & Compliance assistant, easier can be implemented and performs relatively well also in less developed environments. A broader use case, such as the IT assistant, requires more effort to perform at a high level but may be even more beneficial than in the narrow use case once sufficiently refined.  

Från mitten av 1900-talet har virtuella assistenter utvecklats och förfinats där teknologin gått från en mängd regler till assistenter drivna av artificiell intelligens. Idag kan virtuella assistenter tillföra värde till organisationer och bidra till ett hållbart samhälle bland annat genom att utföra enkla och återkommande uppgifter samt minska ojämlikheter orsakad av partiska rådgivare i känsliga frågor. Trots framgången har nuvarande forskning inte fokuserat på evalueringen av virtuella assistenter i industriella sammanhang. Syftet med denna rapport är att utvärdera virtuella assistenter…

2. Strutynskiy, Maksym. A concept of an intent-based contextual chat-bot with capabilities for continual learning.

Degree: computer science and media technology (CM), 2020, Linnaeus University

URL: http://urn.kb.se/resolve?urn=urn:nbn:se:lnu:diva-99102 

Chat-bots are computer programs designed to conduct textual or audible conversations with a single user. The job of a chat-bot is to be able to find the best response for any request the user issues. The best response is considered to answer the question and contain relevant information while following grammatical and lexical rules. Modern chat-bots often have trouble accomplishing all these tasks. State-of-the-art approaches, such as deep learning, and large datasets help chat-bots tackle this problem better. While there is a number of different approaches that can be applied for different kind of bots, datasets of suitable size are not always available. In this work, we introduce and evaluate a method of expanding the size of datasets. This will allow chat-bots, in combination with a good learning algorithm, to achieve higher precision while handling their tasks. The expansion method uses the continual learning approach that allows the bot to expand its own dataset while holding conversations with its users. In this work we test continual learning with IBM Watson Assistant chat-bot as well as a custom case study chat-bot implementation. We conduct the testing using a smaller and a larger datasets to find out if continual learning stays effective as the dataset size increases. The results show that the more conversations the chat-bot holds, the better it gets at guessing the intent of the user. They also show that continual learning works well for larger and smaller datasets, but the effect depends on the specifics of the chat-bot implementation. While continual learning makes good results better, it also turns bad results into worse ones, thus the chat-bot should be manually calibrated should the precision of the original results, measured before the expansion, decrease.

3. Kazilas, Panagiotis. Augmenting MPI Programming Process with Cognitive Computing.

Degree: computer science and media technology (CM), 2019, Linnaeus University

URL: http://urn.kb.se/resolve?urn=urn:nbn:se:lnu:diva-88913 

Cognitive Computing is a new and quickly advancing technology. In thelast decade Cognitive Computing has been used to assist researchers in theirendeavors in many different scientific fields such as Health & medicine,Education, Marketing, Psychology and Financial Services. On the otherhand, Parallel programming is a more complex concept than sequentialprogramming. The additional complexity of Parallel Programming isintroduced by its nature that requires implementations of more complexalgorithms and it introduces additional concepts to the developers, namelythe communication between the processes (Distributed memory systems)that execute the parallel program and their synchronization (Share memorysystems). As a result of this additional complexity, a lot of novice developersare reserved in their attempts to implement parallel programs. The objectiveof this research project was to investigate whether we can assist parallelprogramming process through cognitive computing solutions. In order toachieve our objective, the MPI Assistant, a Q&A system has been developedand a case study has been carried out to determine our application’s efficiencyin our attempt to assist parallel programming developers. The case studyshowed that our MPI Assistant system indeed helped developers reduce thetime they spend to develop their solutions, but not improve the quality ofthe program or its efficiency as these improvements require features that areout of this research project’s scope. However, the case study had limitednumber of participants, which may affect our results’ reliability. As a nextstep in our attempt to determine if cognitive computing technologies are ableto assist developers in their parallel programming development, we movedto investigate if cognitive solutions can extract better and more completeresponses compared to our manually-created responses that we created forthe MPI Assistant. We have experimented with 2 different approaches to theproblem. An approach where we manually created responses for the MPIAssistant, and an approach where we investigated if cognitive solutions canautomatically extract better and complete responses. We compared the qualityof the latter automatic responses with the quality of the former which weremanually created.
