Intelligent search machine with the semantic support

This article introduces an implementation of the search machine with the semantic support based on J2EE technologies. The article focuses on an extraction of new information using nonmonotonic rules. The implementation contains harvester, document preprocessing module, module for document transformation to semantic network, and search module. The search module provides an inference within the semantic network. The implementation was built in the way ensuring the implementation maintainability and its future scalability. One of the attributes of the implementation of semantic network is the possibility of direct insertion of rules.
