Building lexical tools to manage information written in Spanish

Most of the largest operating systems and information retrieval tools do not provide lexical tools for Spanish, which makes it very difficult to check the information fed to the systems. This problem is especially critical in big organisations (libraries, museums, etc) where information is acquired mechanically by scanning or typing, which adds to the already existing errors, new errors caused by the mechanisation process. The need to filter large amounts of information written in Spanish led us to build lexical tools for the Spanish language. This paper presents COES, a complete environment that allows the user to deal with Spanish grammatical problems. Special emphasis has been made on formal specification of Spanish grammar, word tagging and dictionary generation. Finally, some evaluation results of the spelling services are shown. COES has been freely distributed since the end of 1994.
