On the use of ontologies to guide agents answering questions

Abstract

The tasks related to answering a question or clarifying doubts are determined primarily by a good analysis of the question in order to identify the target subject of the response. This paper presents a question-answer system (QAS) that uses ontologies and information retrieval techniques in analyzing the question and thus improving the extraction of a relevant response, most importantly, from resources available on the Internet. © Springer International Publishing Switzerland 2014.
