My research work in Natural Language Processing (NLP) is based on unsupervised approaches.
We are working towards employing unsupervised Word Sense Disambiguation(WSD) techniques to the problems like:
1. Proper Name Discrimination
2. Email Categorization
3. Synonym finding / word clustering
We use and extend SenseClusters for the above problems, which is originally developed by Dr. Ted Pedersen and Amruta Purandare.
