Creating Health Awareness through Social Media Analytics

Supervisors: Dr. R.D. Nawarathna
Students: Mr. J. Selvarajah and Mr. T.M.M.B. Abeysinghe

Main objectives of this research are as follows.

  • To develop a general framework to make health recommendations by analyzing health related content shared in the social media.
    • The first phase of this research focuses on sentiment analysis of health-related twitter posts with special attention towards improving health awareness.
    • The framework will be developed as a general framework for social media analytics so that it can be extended to create awareness and recommendations in other areas such as news, jobs, events and valuable tips for day-to-day activities and so on.
  • To provide the overall opinion about a particular subject as a list of top stories or a summary


M.Sc. Research

Brain Tumor Classification using Deep Learning Techniques

Supervisors: Dr. R.D. Nawarathna
Student: Ms. N. Balasooriya

The objective of the research is to develop a software to detect the tumor type within minimum time when a collection of digital MRI data of a single patient is given. To achieve this goal, a deep learning approach is developed. More than 60,000 MRI scans of diagnosed patients and control groups are used to train a deep neural network model.
