Un sistema de búsqueda de respuestas basado en ontologías, implicación textual y entornos reales

This paper presents an user–centred ontology– and entailment–based Question Answering system. A methodology is proposed in order to carry out the construction of the user knowledge database. This knowledge database allows us to fill the gap between natural language expressions and formal expressions such as database queries. The core of the system relies on an entailment engine capable of deducting inferences between queries and the knowledge database. The system has been developed for Spanish, covering the cinema domain and obtaining very promising results within real environments.
