My research interests are in the area of information retrieval and text processing. My thesis advisor was (late) Prof. Gerard Salton. My current thesis supervisors are Dr. Chris Buckley and Prof. Claire Cardie
Here is a postscript copy of my resume.
The Smart group at Cornell CS department has been one of the foremost research groups in the field of information retrieval for last thirty years. Our current research involves:
To fairly retrieve texts of varying sizes, document length normalization is commonly used in term weighting. We show that effective systems should retrieve documents of all sizes with chances similar to their likelihood of relevance. We propose pivoting, a new technique that can be used to modify existing normalization functions to yield substantial improvements in retrieval effectiveness. We also propose a new and effective normalization technique.
Text REtrieval Conference (TREC) is a NIST and ARPA co-sponsored effort to objectively evaluate various information retrieval techniques on an independent testbed. The Smart system has consistently been one of the best systems at TREC.
Non expository texts are not usually read from cover to cover. Readers are helped in such circumstances by providing selective access to text excerpts as needed. We have developed techniques to analyze the structure of a text and provide tools for selective text traversal.
