Research Interests

My research interests consist of Natural Language Processing and Machine Learning. Primarily, I am interested in the applications of Word Sense Disambiguation to Subjectivity/Sentiment Analysis. I am particularly interested in active learning and semi-supervised learning methods and also crowdsourcing. Beside this, I also worked on Information Extraction in medical domain. Here is my up-to-date Curriculum Vitae.
