Prof. Rajeev Sangal's research interests in Natural Language Processing(NLP) are in the areas of natural language parsing, tree banking, and machine translation. He has combined novel computational grammatical models with machine learning to achieve interesting results in parsing of free word order langauges. He also looks at knowledge representation and linking it with grammatical representation. He has also developed a software architecture for NLP in general and machine translation in particular.
