English abstract

The lack of systems endorsed to call the genes is a problem for the identification of information in the biomedical literature and does very difficult an essential process in the field of the molecular biology: finding and to discover biological relations among genes, in those documents that treat the same genomic entity but that they use different symbols. We propose a procedure taken from the of natural language processing (NLP) based on the application of transducers of finite-state that allows the recognition of the diverse names of a gene and relates them to an unified form. The process of standardization requires as input a list of synonyms, and as an output an unique identifier for that gene. The genomic database FlyBase has contributed us the necessary resources to expose our proposal.

La falta de sistemas homologados para denominar a los genes es un problema para la identificación de información en la literatura biomédica y hace muy difícil un proceso esencial en el campo de la biología molecular: encontrar y descubrir relaciones biológicas entre genes, en aquellos documentos que tratan la misma entidad genómica pero que usan símbolos distintos. Nosotros proponemos un procedimiento adoptado del procesamiento de lenguaje natural (PLN) basado en la aplicación de transductores de estado-finito que permite el reconocimiento de los diversos nombres de un gen y los relaciona con una forma unificada. El proceso de normalización requiere como input una lista de sinónimos, y como output un identificador único para ese gen. La base de datos genómica FlyBase nos ha aportado los recursos necesarios para exponer nuestra propuesta.
