Prueba de Concepto de Expansión de Consultas basada en Ontologías de Dominio Financiero

This paper explains the application of ontologies in financial domains to a query expansion process. The final goal is to improve financial information retrieval effectiveness. The system is composed of an ontology and a Lucene index that stores and retrieves natural language concepts. An initial evaluation with a limited number of queries has been performed. Obtained results show that ambiguity remains a problem when expanding a query. The filtering of entities in the expansion process by selecting only companies or references to markets helps in the reduction of ambiguity.
