Abstract

Question analysis is a central component of Question Answering systems. In this paper we propose a new method for question analysis based on ontologies (QAnalOnto). QAnalOnto relies on four main components: (1) Lexical and syntactic analysis, (2) Question graph construction, (3) Query reformulation and (4) Search for similar questions. Our contribution consists on the representation of generic structures of questions and results by using typed attributed graphs and on the integration of domain ontologies and lexico-syntactic patterns for query reformulation. Some preliminary tests have shown that the proposed method improves the quality of the retrieved documents and the search of previous similar questions.
