A model of a generic Arabic language interface for multimodel database

The extraction of the information from database systems requires the formulation of queries using database query languages, such as Structured Query Language (SQL). This formulation needs the knowledge of the model and the structure of the database. However, non-expert users cannot write such queries. This is why a lot of works have been developed to query the database in natural language. Historically, most of these works were carried out for English language and they were designed for a specific database model. Some of them function independently of database domain. But, until now there is no system that functions independently of both database model and domain. For the Arabic language, all existing contributions are dependent on database domain and model. This paper presents a generic natural language interface to query databases using the Arabic language. This interface functions independently of the database domain and model (relational and XML). Furthermore, the use of machine learning helps our system to improve its knowledge base automatically through experience.
