- 1996-2000 Constraint Based Knowledge Brokers system on data integration from heterogeneous corporate and Web resources. We developed techniques for the query mapping and translation, the mechanism of semantic cache for the efficient query processing, and the wrapper generation for Web resources.
- 1999-2003, Iwrap system on the induction of Web wrappers. The Iwrap combined methods of grammatical inference with the active learning, it offers a GUI-based interface for inferring wrapper instances from a small number of annotations. The wrapper designer was a core component of the AskOnce content integration platform, commercialized by Xerox in 2000 and acquired by Documentum in 2004. The analysis of commercial deployment of AskOnce wrappers during the 2003-2005 period has been published in ACM SIGMOD'2006.
