Research

Overview

I am interested in the text analysis using topic modeling in medical, social networks,management, library science, and mobile networks domains.

Current research projects investigate:

Applications of data\text mining in interdisciplinary areas
Developing topic models using fuzzy clustering
Developing methods to detect spams in mobile, online reviews, social networks, and web

Research Interests

Health and Medical Informatics
Big Data & Text Mining
