Formal semantic analysis and modeling of natural language Wh-question

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 linguistic analysis based query model called Description Logic based Wh-Query Modelthat syntactically characterizes wh-queries in English and has a complete semantic equivalency to Description Logics (DL). This work also includes a rules to identify desire depedency in case of complex and compound query. We evaluate the query characterization coverage using Microsoft Encarta query dataset and OWLS-TC V4.0 service query dataset.
