Yochan Information Integration Group

We are broadly interested in developing flexible frameworks for data and information integration. Our projects include BibFinder, Havasu, and Emerac. We are part of ET-I3 a university-wide initiative on Intelligent Information Integration.

Members

• Professor Subbarao Kambhampati.

• Zaiqing Nie is working on BibFinder, a meta-search engine for bibliographic entries, that uses automatically gathered coverage and overlap statistics. Earlier, he had done work on multi-objective query optimization for data integration scenarios.
• Ullas Nambiar is working on supporting imprecise queries in information aggregation scenarios
• Thomas Hernandez is working on integrating bio-informatics data sources, and on statistics-oriented approaches for meta-search on text databases.
• Jianchun Fan is working on flexible approaches for web-service composition

Alumni

• Eric Lambrecht developed the Emerac data integration system, that uses a novel framework for supporting recursive information gathering queries.
• Sreelakshmi Vaddi worked on adaptive execution techniques for data integration scenarios.
