Publication Embargo VTutor: A Platform for Improving Searchability and Interactivity of Recorded Lectures(IEEE, 2019-12-05) Karunaratna, D; Hettiarachchi, I; Fernando, S; Epa, S; Kodagoda, N; Suriyawansa, KRecorded lectures have gained popularity as a method of delivering lecture content as they give learners a host of distinct advantages such as the ability to follow lectures without time or location constraints and to consume the lectures at their own pace. However, despite such benefits, they have a tendency to be lengthy and tedious to watch. They also prove cumbersome when precise information needs to be extracted from the content. Another drawback is that recorded lecture videos fail to show the connection between the lecture and its support material such as slides and questionnaires. Though many of the existing platforms allow editing lecture videos for more interactivity, the methods employed by these platforms have always been manual, and therefore time intensive. VTutor is a web platform that aims to address these drawbacks by introducing automation into the video enhancement process, eventually combining the lecture material to create an enhanced user experience. Specifically, VTutor allows users to navigate through a lecture video using subtopics, its corresponding slides and code samples. Furthermore, it is equipped with the ability to automatically generate questions by scraping the internet based on provided keywords thus improving the level of engagement that a learner has with the lecture.Publication Embargo Zilla: An Animal Based Social Media Platform(IEEE, 2019-12-05) Kasun, R; Mahesh, L. G. H; Yapa, Y; Suwendra, S. M. S. D; Kodagoda, N; Suriyawansa, KPets have been part of human societies from ancient times. The purpose of having a pet might have been changed, the breeds of pets have been evolutionarily changed making them tamed and friendly to have in the modern urbanized society. Pet owners consider their pets as one of their family members and love them immensely. Moreover, pet owners face difficulties when their pet gets sick and there is no emergency veterinary support, or even the owner might be unsure about conditions that affect the pet's life. In this research a social media platform called Zilla devoted to pets is presented. This Pets based social media platform provides pet owners a unique platform to interact with other pet owners.Publication Embargo gCodex: A tool to analyze software repositories over time (visualization)(IEEE, 2019-12-05) Nuzrath, S; Amarasinghe, N. H; Liyanage, K. T; Suriyawansa, K; Madanayake, D. P; Kodagoda, NgCodex is a novel tool for analyzing and visualizing the code base in a manner that it allows its users to get an idea of the insights of the codebase. This tool was built to analyze code bases and it supports any language. In addition, it provides a visualization of the file structure, rate of change of complexity and defects rate. In order to improve the quality of the software and the controllability of the project, it is necessary to control the complexity of the software by measuring the associated aspects and visualize those in a descriptive and attractive dashboard. Using the existing tools, it is not possible to visualize the rate of change of code complexity with the time. This tool uses Cyclomatic complexity, line of code and Halstead complexity metric and their impact on the software quality, and visualize those in a descriptive dashboard which provides analytics that describes and summarize past trends.Publication Embargo MOOCRec 2 for Humanities-Learning Style Based MOOC Recommender and Search Engine(IEEE, 2019-12-05) Fazuludeen, F; Vijayakumaran, G; Mahroof, Z. A; Kodagoda, N; Suriyawansa, KIntroduction of Massive Open Online Courses (MOOC) has a great impact on the e-learning sector. Further, MOOC platforms like Coursera, EdX, and Future Learn have made learning accessible to millions of people for free. Also, availability of such platforms has become a blessing and a burden to people since users cannot find the right courses that suits them due to the availability of similar topic of courses in different platforms. Moreover, MOOCRec Humanities is a curated search platform for these courses. Further, MOOCRec tries to address this problem by considering the learning style of user and matching them with the right courses. Additionally, the courses are mapped using VARK learning model. For the mapping purpose, course video styles and course practical content such as quizzes and reading materials are considered. In addition, users can search individual topics that can be covered in a course.Publication Embargo TOURGURU: tour guide mobile application for tourists(IEEE, 2019-12-05) Thennakoon, M.S.B.W.T.M.P.S.B; Rajarathna, R. D. T. N; Jayawickrama, S. P. B; Kumara, M. P. D. S. M; Imbulpitiya, A. M; Kodagoda, NThe paper discusses a tour guide mobile application which uses cloud computing, machine learning and Augmented Reality (AR) to give the user an amazing experience on tourism. This application would guide users through an appropriate route to a traveler's destination while suggesting recommended attractions through the route. Tourists would also be given the opportunity to listen to a narration about certain monuments while they are walking or driving through the suggested route. Additionally, one from the available two of the AR features can be useful when a tourist wants to find which direction a certain attraction is. This feature would be especially useful on a high vantage point allowing the user to enjoy several attractions from the same place all the while receiving interesting facts about them. Also, it would contain various details about that said attraction. Other feature of AR is on 3D object modelling that helps the user to get the experience of Point of Interest (POI).Publication Embargo MOOCs Recommender Based on User Preference, Learning Styles and Forum Activity(IEEE, 2019-12-05) Hilmy, S; De Silva, T; Pathirana, S; Kodagoda, N; Suriyawansa, KWith the development of MOOCs (Massive Open Online Courses) as a major source of e-learning materials, the number of MOOCs available today has become dauntingly high. Furthermore, MOOCs are produced in many different video production styles and these styles play an important role in helping the consumer stay engaged and interested in the course throughout. However, due to the sheer number of MOOCs available today, it is becoming increasing difficult to find the MOOCs that suits your personal preferences and the learning style. This paper describes how thousands of MOOCs that belong to different styles are identified efficiently while each consumer's preferences are identified to provide personalized MOOC recommendations. Furthermore, the paper describes how forums can be analyzed to identify how consumers feel about MOOCs that they followed, which is a crucial metric in recommending MOOCs to consumers.
