Detecting human emotions on Facebook comments
(IEEE, 2020-09-24) Chathumali, E. J. A. P. C; Thelijjagoda, S
Human emotion detection plays a vital role in interpersonal relationships. From the early eras, automatic recognition of emotions has been an active research topic. Today, sharing emotions on social media is one of the most popular activities among internet users. However, when it comes to a specific domain like emotion detection in social media, it is still on a research-level. There are less number of applications have been developed to detect emotions online, using online comments and user comments. The aim of this research is to develop a system that identifies human emotions on Facebook comments. Among the different social media platforms, this research specifically focuses on Facebook comments written in the English language to narrow down the problem. The research is based on Semantic analysis, which comes under Natural Language Processing (NLP) and the system development consists of four major steps, including the extraction of Facebook comments via Graph API, preprocessing, classification and emotion detection. To classify the emotions, a classification model was created by using Naïve Bayes Algorithm. When it comes to marketing, emotions are what lead your onlookers to purchase. By using the detected emotions, marketers can promote their campaigns by changing online advertisements dynamically. The results obtained through testing the system show that it is capable of accurately identifying human emotions hidden in Facebook comments with an accuracy level of 80%, making it highly useful for marketing purposes.

Green Cloud Computing: A Review on Adoption of Green-Computing attributes and Vendor Specific Implementations
(researchgate.net, 2019-03) Jayalath, T; Chathumali, E. J. A. P. C; Kothalawala, K. R. M; Kuruwitaarachchi, N
With cloud computing emerging as a trending topic, it has been a major point o f discussion for the last few years. In regards to technological advancements, the associated shortcomings like environmental footprint caused by them also become an affair o f high significance. Cloud computing itself is a much greener alternative to individual data centers with lesser number o f servers being used and cloud data centers being far more efficient than those o f traditional thereby reducing the carbon impact. Nonetheless, it cannot be neglected the fact that the data centers utilized by the cloud vendors are still a major source o f carbon emissions due to the dirty energy usage. Therefore, the discussion o f the paper is based on how green the foremost cloud providers are and the implementations o f green IT attributes in the cloud infrastructure.

Speecur: Intelligent pc controller for hand disabled people using nlp and image processing
(GARI Publisher, 2017-06-30) Chathumali, E. J. A. P. C; Jayasekera, J. M. U. B; Pinnawala, D. C; Samaraweera, S. M. T. K; Gamage, M. P. A. W
Today computers play a major role in human lives. Even though there are very sophisticated interfaces, differently abled people find it challenging to interact with the computer. There are some applications for disabled people, but people who have disabilities in hands do not have a proper application to interact with new technologies. The aim of this project is to develop software that act as an intelligent controller to facilitate hand disabled people when interacting with a computer. Proposed intelligent solution is based on speech recognition, image processing and human computer interaction. This application is capable of moving mouse cursor with face detections, activities based on voice commands, provide user authentication by voice recognitions and give suggestions using facial emotions. The solution will be using various high end techniques in Natural Language Processing, Machine Learning and Image Processing in order to improve the computer interaction. The proposed solution will be a great solution for the hand disabled people to interact with the computers like a normal user does.
