Short Bio
I am a fourth year graduate student at the Center for Intelligent Information Retrieval (CIIR). Prior to joining CIIR, I was a software engineer at the Center For Natural Language Processing(CNLP) at Syracuse University. I completed my Masters degree in Computer Science at the University of Buffalo in 2003. You can find a detailed resume here.
Research Interests
Mobile Information RetrievalI am interested in understanding the impact of system constraints on information retrieval from mobile phones.
For instance, energy consumption of network activity is a key constraint on mobile phones and has a direct impact on web search which is essentially an interactive network application [IMC 2009].
Sentence Retrieval
Idetifying sentences that contain overlapping information is useful for several natural language applications such as Text Reuse Detection, Multi-Document Summarization, and Novelty Detection. I explored retrieval of restatements as a sentence retrieval task, comparing statistical approaches [SIGIR 2007] and proposed effective syntactic query models in a language modeling framework [SPIRE 2009].
Automatic Topic Pages
As an alternative to the standard ten blue links for presenting search results, I explored automatically generating topic pages which present information on diverse aspects pertaining to the topic [CIKM 2009].
