Formal semantic simplification of Wh-query in english

Abstract

The problem of Natural Language Query Formalization is to understand the semantics of a user given query in natural language (NL) and then translating the Query into a formal language (FL) such that the FL semantic interpretation has Equivalence with the NL interpretation. Such linguistic analysis based formalization can be used as more accurate query analyzer when compared to statistical analyzers. In this thesis work we have proposed a way of characterizing the natural language query’s in English to the characterization template and further this template will be used by description logic (DL) to capture the semantic of the query. The goal of the thesis would be to get the consistent answers for all the semantically same queries. This work also includes a algorithms to characterize the simple, complex and compound Wh-query. We evaluate the query characterization coverage using Microsoft Encarta query dataset and OWLS-TC V4.0 service query dataset.
