Ontology-Based Information Retrieval: Development of a Semantic-Based Tool for the Media Industry

Abstract

This paper describes the creation of an RDF ontology designed to support information retrieval needs of journalists and media professionals. The purpose of the ontology is to complete the automated extensions of query terms by using the relationships between the concepts and terms registered in the ontology. By using this ontology, end-users can identify additional concepts that are related to the selected topic, and incorporate new terms to the query that will be later launched against a full-text indexer based on SOLR. The ontology focuses on politics, and has been successfully tested with the collaboration of a large Spanish media company. The ontology contributes to a better recall of the search results.
