Dbpedia Based Factoid Question Answering System

Abstract

ABSTRACT Question Answering (QA) is an area of natural language processing research aimed at providing human users with a convenient and natural interface for accessing information. Nowadays, the need to develop accurate systems gains more importance due to available structured knowledge-bases and the continuous demand to access information rapidly and efficiently. In This paper we propose a new architecture to develop a factoid question answering system based on the DBpedia ontology and the DBpedia extraction framework. We use the SVM learning machine algorithm to train the systems question classifier to achieve a high accuracy ratio. The design and implementation steps are covered with sufficient details. In addition, tests and experiment results of the developed system are presented with a short discussion about the systems efficiency
