Selected Projects in this position:
Texterra – Semantic Text Mining and Search

Texterra (http://modis.ispras.ru/texterra) takes a novel approach to semantic text mining and search by utilizing semantics extracted from user-generated knowledge bases (such as Wikipedia, etc). It mines Wikipedia to build a semantic network with more than 6 millions nodes (for English Wikipedia). The network is then used to interpret meanings and relationships of terms in arbitrary text documents. There are two products based on the Texterra technology: (1) ad targeting system for Web pages; (2) search and navigation engine for Blogosphere (http://blognoon.dyndns.org/)

Sedna – Native XML Database System (2003 – present)

Sedna is a leading open-source native XML database. It provides a full range of core database services - persistent storage, ACID transactions, security, indices, hot backup. Support for W3C XQuery implementation, tight integration of XQuery with full-text search facilities and a node-level update language. More information: http://modis.ispras.ru/sedna/

Content Management Solution for “Great Russian Encyclopedia” Publishing Company www.greatbook.ru (2006-2007)

Full lifecycle content and knowledge management solution for production of encyclopedias and references. The solution provides a single-sourcing publishing with content reuse, various editorial services (version management, content validation), publishing on various media (paper, Web, DVD), superior search & navigation. It is an XML-centric solution based on Sedna XML database.
