Propuesta De Extracción Automática De Candidatos a Término Del Dominio Médico Procesando Información Lingüística. Descripción Y Evaluación De Resultados

Abstract

• ABSTRACT: The description of a method for automatic extraction of term candidates from the medical field by applying linguistic information is presented. Lexicography, morphological and syntactic rules were used. First, the detection was performed by applying a standard dictionary that assigned the tag ´MED´ ('MEDICAL') to the words that could be considered terms. Morphological and syntactic rules were used to try to deduce the part of speech of the words that were not considered in the dictionary (WNCD). Afterwards, nominal phrases that included WNCD and MED were gathered to extract them as term candidates of the field. Smorph, Post Smorph Module (MPS) -both work in groups-and Xfst were the software used. Smorph performs the morphological analysis of character strings and MPS works on local grammar. Xfst is a finite state tool that works on character strings assigning previously stated categories to allow the automatic analysis of expressions. This method was tested on a section of the corpus of clinical cases collected by Burdiles (2012) of 217258 words. The results showed 92.58% of precision, 95.02% of recall and 93.78% of F-measure.•
