Publication Embargo Enhancing Conversational AI Model Performance and Explainability for Sinhala-English Bilingual Speakers(IEEE, 2022-12-09) Dissanayake, I; Hameed, S; Sakalasooriya, A; Jayasinghe, D; Abeywardhana, L; Wijendra, DNatural language processing has become essential to modern conversational tools and dialogue engines, including Chatbots. However, applying natural language processing to low-resource languages is challenging due to their lack of digital presence. Sinhala is the native language of approximately nineteen million people in Sri Lanka and is one of many low-resource languages. Moreover, the increase in using code-switching: alternating two or more languages within the same conversation, and code-mixing: the practice of representing words of a language using characters of another language, has become another major issue when processing natural languages. Apart from natural language processing, the explainability of opaque machine learning models utilized in chatbots has become another prominent concern. None of the existing modern chatbot development platforms supports explainability and relies on a performance score such as accuracy or f1-score. This paper proposes a no-code chatbot development platform with a series of built-in novel natural language processing, model evaluation, and explainability tools to tackle the problems of processing Sinhala-English code-switching and code-mixing natural language data and model evaluation in modern chatbot development platforms.Publication Embargo Impact of Critical Success Factors in Oracle EBS Enterprise Resource Planning Post Go Live Implementation:A Case Study on SriLankan Airlines(Institute of Electrical and Electronics Engineers, 2022-01-08) Dissanayake, I; Thelijjagoda, SIn today's business world, ERP does everything from recording transaction data, managing workflows, analyzing data to provide insights to decision makers for effective decision making. Selection of a right ERP, proper testing and post go live could be a major scale system implementation for any organization. Thus, it is extremely beneficial to evaluate and test the Critical Success Factors (CSFs) in order to ensure a successful ERP post go live implementation. The primary goal of this study is to determine the impact of Critical Success Factors that influence for a successful post go live ERP implementation in the context of the national airline of Sri Lanka which is SriLankan Airlines. Three critical success factors were identified through this study. This study aims on Adequate end user training, Business Process Management (BPM) and Top Management Support as CSFs. The findings have verified that the ERP implementation success is influenced by the Top Management Support, Business Process Management and adequate end user trainings. Out of the identified three CSFs, it is statistically proven that the adequate end user training takes a significantly prominent place for a successful post go live implementation while BPM and Top Management Support also equally contribute to drive an ERP implementation project with expected outcomes. This study could be a guidance for enterprises, be beneficial to ERP clienteles, ERP consultants and service providers, be added to the existing body of knowledge.Publication Embargo Impact of Critical Success Factors in Oracle EBS Enterprise Resource Planning Post Go Live Implementation:A Case Study on SriLankan Airlines(IEEE, 2022-06-14) Dissanayake, I; Thelijjagoda, SIn today’s business world, ERP does everything from recording transaction data, managing workflows, analyzing data to provide insights to decision makers for effective decision making.
