AZRAEL is a rule-based automatic language detector based on the syllable structure coded in Prolog. The first version only detected Spanish language and was released in 2009. Since then, French, Italian, Portuguese, Catalan, Latin and Basque language have been added to the project. The doc folder contains the report and poster for the 2009 version of AZRAEL. This project received in 2009 the First Award at the VIII Arquimedes Contest for Young Researchers awarded by the Spanish Ministry of Science and Education.
