In our ongoing research and development project, called “In the Web of Words” (WoW), funded by the National R+D Program in Hungary, we aim to create a complex search interface that incorporates—beside the usual keyword-based search functionality—(1) deep web search, (2) Hungarian natural language question processing, (3) image search support by visual thesaurus. This paper focuses on a particular and crucial part of the question processing problem (2): recognition of entities. Entities are expressions that have fixed form, and that are assigned context specific information in the dictionary. Due to the agglutinative feature of Hungarian language they often appear in the text differently as in the dictionary, therefore their detection requires special algorithms at processing.
