Architectural Framework for Electronic Legal Solution Development.
(8th International Conference on Business & Information ICBI – 2017, Faculty of Commerce and Management Studies, University of Kelaniya, Sri Lanka., 2017) Vasanthapriyan, S.
In the context of ever increasing numbers of legal cases and involved stakeholders in multi-party collaborations, we have discovered the appropriateness of the adaptation of more advanced information communication technology (ICT) in legal sector to address the resulting complexities and performance issues in legal service collaborations and their flow of information exchanges among different participants, which are fundamental to obtain cost effective and best professionally practiced legal services. Most of the time, systematic guidelines that could facilitate legal service solution designing and deployment, not only to identify the complex multi-party collaboration processes within and between legal organizations and legal service providers, but also to identify the nature of the information handled by the collaborative parties, is a primary requirement for clear transformation of legal service strategies into electronic systems. We have proposed a methodological framework which combines two sub-frameworks, while ensuring the alignment with Service Aware Interoperability Framework (SAIF) recommendations with the objective of understanding the legal service collaboration processes as well as of identifying the nature of the information handled by the collaborative parties, in such a way to provide a useful input for the creation of electronic legal systems. The architectural framework was developed based on Business Transaction View meta-model in UN/CEFACT’s recommendations for business collaborations. By applying the proposed framework in legal sector, it has been illustrated how the activities and information can be used in realizing services related to the domain when developing service solutions.

(Department of Zoology and Environmental Management, University of Kelaniya, Kelaniya, Sri Lanka., 2016) Vasanthapriyan, S.; Thuseethan, S.
Interest on how undergraduate students organize and coordinate their work such as assignments, group studies, etc. in collaborative groups through research on ICT supported collaborative learning has increased in recent years. These innovative collaborative platforms encourage students to share ideas, experiences and thought with the others. Our study aimed to explore science faculty students from three universities about the use of web 2.0 for their collaborative learning activities. We collected sample size of 529 student’s opinions which is composed of 189, 175 and 165 from each university. Most of the undergraduate students ( 96.5%) are aware of Web 2.0 and almost using it in their daily life too. Further, 2.9% of the students from the sample do not know about the term Web 2.0 but they are also using it for such collaborative activities. Comparing to the first year students’ (over all 13.01%), special degree students from third (over all 35%) and fourth year (over all 45%) are using this environment for student learning. These results suggest that most of the students are using Web 2.0 tools for their collaborative activities. They mainly use ICT based collaborative environment for chatting and discussion, content creation, file sharing, enjoyment and entertainment of four categories to construct knowledge, share knowledge and improve their learning performances. They mainly face less technological infra structure support from universities (over all 91.29%) which costs students to purchase themselves data offers (76.45% of students from all three universities regularly buy 10GB or more per month) from mobile providers to use within their university residence facilities and in common rooms inside the university premises. These discovered hidden problems and obstacles should be seriously taken into consideration by the university administration to improve the collaborative study environment among students to keep students busy with their learning activities
Improve safety for pedestrians using smartphones while walking: Sri Lankan context
(Department of Zoology and Environmental Management, University of Kelaniya, Kelaniya, Sri Lanka., 2016) Vasanthapriyan, S.; Thuseethan, S.; Dantanarayana, G.
The prosperity of smartphones greatly improved the convenience of our everyday life and also increased our dependence on them. Further, free Wi-Fi and lot of data offers have been given to public in Sri Lanka such that increasing number of population are using their smartphones even on the street while walking on the roads. Thus, increasing number of pedestrian got injured or killed during texting/talking while-walking. The phenomenon that pedestrians use smartphones while walking has posed great threat to transportation safety as well. In this paper, we discuss the design of smartphone graphical user interface in safety-critical environments systematically. A preliminary questionnaire based study was conducted to collect smartphone users’ opinions/attitudes towards using smartphones while walking. Some safety-critical details were also collected. A novel Walking Mode was introduced and one possible framework was proposed to improve safety for pedestrians using smartphones while walking. Our framework consists of three modules and could provide insights for smartphone designers as well as guide application designers to design safety- based context-aware GUI. Keywords: Walking mode; context-aware graphical user interface; real-time scene parsing system; safety-based indicator.
Influence of Human Computer Interaction in Learning Management System
(Department of Zoology, University of Kelaniya, Kelaniya, Sri Lanka, 2014-06) Thuseethan, S.; Vasanthapriyan, S.
The word E-learning in many developing and developed countries is inseparable from the field of education and more common in nature. The usefulness of Learning Management Systems in e-learning lies not only in performing the academic task itself but also in sharing of knowledge between users, which includes academics and students. The current trend in developing Learning Management Systems is largely empirical, and academically sound learning experiences are still absent. At the first glance faster, more flexible, more natural, easier and more convenient means for users and Learning Management Systems to interchange information are required. In user‘s perspective, the use of Learning Management System is constrained by the human‘s perceptual and cognitive abilities. On the other hand, in computer side, it constrained only by devices used in the system and the limitations in software design. The best way to overcome both types of constraints therefore now totally lies in designing the user interface rather than the internal system design. In this research appropriate strategies for developing interfaces to Learning Management Systems at a national level were considered. The issues in designing interfaces for Learning Management System for academics are little different from the design standard of interfaces taken from the literature of Human Computer Interaction standards. These differences were considered with the help of a survey done in an academic organization and are described, explained, and clarified. Finally we came up with some modification of standards with the help of existing standards in Human Computer Interaction and with the research output. This type of Human Computer Interaction standards for Learning Management System can satisfy the desires of its intended academic users and deliver a suitable opening for advance research and development.

Knowledge based system for software testing
(International Research Conference on Smart Computing and Systems Engineering - SCSE 2018, 2018) Vasanthapriyan, S.
Software development is conceptually a complex, knowledge intensive and a collaborative activity, which mainly depends on knowledge and experience of the software developers. Software testing is a sub area of software engineering which is also a knowledge intensive and collaborative activity. Effective software testing activities relies on the knowledge collaboration where every software tester shares his/her knowledge or acquires knowledge from others. Finding relevant knowledge within the software testing team or within the experts inside the company is not an easy task. There is a need to represent and process knowledge in an affordable and manageable manner. In this context, principles of knowledge management are pointed out as an important means to manage software testing knowledge. The research contributes in knowledge management in software testing, especially managing the software testing knowledge. An ontology based expert system is designed to share software testing knowledge and can be used to support sharing of knowledge and learning practices in other software companies.

(Department of Zoology, University of Kelaniya, Kelaniya, Sri Lanka, 2014-06) Wickramasingha, W.A.K.L.M.; Kudavidanage, E.P.; Vasanthapriyan, S.; Priyadarshana, T.S.
There is a critical need to share and manage biodiversity data for conservation purposes. A comprehensive inventory of biodiversity data on a location together with information on subjects such as habitat use, conservation status, availability of specimens and previous research can benefit both researchers and decision makers. The National Wildlife Training Center (NWTC) is located in the dry zone, close to Minneriya– Giritale Nature Reserve Block II. It is surrounded by well grown Tropical dry mixed forests and harbors a diverse array of fauna and flora including many endemics and nationally threatened species. The center provides compulsory training to staff of the Department of Wildlife Conservation and has facilities for researchers. It is currently being developed to become an International Training School. Therefore, there is a great necessity to have well documented information on the biodiversity of the locality that can be accessed by visitors, trainees and researchers. In addition an advance form of a database can assist to monitor the use of the specimen collection at the museum and help future development of the site that might affect some of the faunal habitats. Thus this project aims to provide knowledge sharing and management solutions using Information and Communication Technology. The objectives of the study are to provide knowledge sharing and management solutions for using Girithale National Training Center as a model, assist maintaining the specimen collection, provide remote access to users, to reduce barrier between researches and application, to simplify the data searching process and to promote data driven decision making. The project used both primary and secondary data. A biodiversity survey was conducted around the training center in the sanctuary since no previous intensive study on the site has been carried out. The field data as well records from the specimen collection was used as the primary source for project. The research reports at the center were used as secondary sources. The data sharing platform constructed is a web site developed using PHP and the Data base using MySQL. Maps were prepared using digital image processing, use queries, search engine or artificial intelligence agent to retrieve data. In addition a mobile web page was also created. The NWTC could host this web site as a knowledge sharing center. This system provides a knowledge sharing and management system that will help to protect rare and threaten habitats of Girithale and also will provide easy access to different studies conducted. Thus it finally will reduce the gap between conservationists, researchers, decision makers and public and will also facilitate more informed decision making and efficient use of resources.
Sentimental Analysis Based on Sinhala Language Social Media Updates
(University of Kelaniya, 2015) Vasanthapriyan, S.
The World Wide Web plays a critical role in collecting public opinion where these opinions play an important role in making business decisions. For factual and subjective information about companies and products, analysts are turning to the Internet to gather information. Extracting public opinion is the difficult task in a country like Sri Lanka, because most of the time the language spoken is, Sinhala or Tamil rather than English. Sentimental Analysis being a major research topic in computational linguistic community is quite popular and has led building of better products, understanding user’s opinion, executing and managing of business decisions. However most of the researches never focused on South Asian languages like Sinhala, often used in Social media websites such as Face book, Twitter and etc. Motivated by Sentimental Analysis researches based on Hindi, another south Asian language, we proposed and developed a system that analyzes social media updates in Sinhala language for the sentiments. Starting with three basic sentiments; Positive, Negative and Neutral we retrieve a set of live updates based on Face book and Twitter. This data set is then deployed in to a cloud service and analyzed and give the proper output. Sinhala is a free order language compared to English which adds complexity while handling user generated content. Our finding focuses on how to build a better platform on sentimental analysis to help bloggers to stop spam, business firms to get feedback, and government firms to get urgent service requests. We hope to do more investigation on implicit factors in Sinhala language and give them as features for the models we described in our work.
Survey on Metadata Standards for an E-Teaching Environment
(Department of Zoology, University of Kelaniya, Kelaniya, Sri Lanka, 2014-06) Vasanthapriyan, S.
E--teaching is commonly referred to as the intentional use of networked information and communications technology (ICT) in teaching and learning processes. In order to be easily retrieved, shared and used by different users and for different purposes, the various types of e- teaching documents have to be described following common schemes and rules e.g. specifications or standards and metadata. But the web lacks a uniform organization scheme that would allow easy access to these e-teaching material. It means that there should be efficient accessibility and the recoverability of educational resources. This objective can be gained using the ―Metadata Standards‖. Several institutions and professionals have established Metadata Standards. In this research, a survey was carried out to find out the existing Metadata Standards and their characteristics to propose common Metadata standards to the e—teaching environment. Therefore, the retrieval of information of various types including print, images, animations, presentations, audio, and video in the environment can be easily done.
