Dr. Parvathi Chundi

Associate Professor

C.S Dept, Univ of Nebraska at Omaha

Email: pchundi@mail.unomaha.edu

Phone: 554-4987

Office: PKI 281A

Teaching: I usually teach the graduate courses on i) design and analysis of algorithms and ii) information retrieval systems. I also teach the undergraduate course on introduction to database management systems.

Research Interests: text mining, temporal mining, bioinformatics, replicated and distributed databases.

Current Research Project: Currently I am working mainly on extracting temporal information from time stamped documents. This work is supported by NSF. More details of the project can be found here. This work has been applied to document sets such as TDT-Pilot Corpus, Reuters News articles, NSF abstracts, Pubmed abstracts, ENRON Email data set as well as software repository data such as Mozilla, Apache, and Eclipse.
