Resumo
La terminología usada en biomedicina tiene rasgos léxicos que han requerido la elaboración de recursos terminológicos y sistemas de recuperación de información con funciones específicas. Las principales características son las elevadas tasas de sinonimia y homonimia, debidas a fenómenos como la proliferación de siglas polisémicas y su interacción con el lenguaje común. Los sistemas de recuperación de información en el dominio biomédico utilizan técnicas orientadas al tratamiento de estas peculiaridades léxicas. Se revisan algunas de estas técnicas, como la aplicación de Procesamiento del Lenguaje Natural (BioNLP), la incorporación de recursos léxico-semánticos, y la aplicación de Reconocimiento de Entidades (BioNER). Se presentan los métodos de evaluación adoptados para comprobar la adecuación de estas técnicas en la recuperación de recursos biomédicos.
