    En este artículo presentamos el sistema AMSABEL, un sistema de acceso a información basado en lenguaje natural. AMSABEL proporciona acceso al contenido de una base de datos relacional, a partir de consultas realizadas en lenguaje natural, tanto en castellano como en inglés. De esta manera se permite un acceso directo a la base de datos por parte de usuarios no expertos. El sistema utiliza aprendizaje automático para traducir la consulta original al lenguaje de consulta estructurado siendo, por lo tanto, independiente del contenido de la base de datos siempre que se disponga de datos de entrenamiento.

    In this paper we present the AMSABEL system, a natural language based information retrieval system. AMSABEL provides access to data stored in a relational database using unrestricted natural language. Queries can be expressed in either, English or Spanish, thereby providing direct access to the database for non-expert users. The system relies on machine learning techniques to translate the original query from natural language into a structured query language and, therefore, does not depend on the contents of the database, as long as training data is available.
