Despite of the spread of Electronic Health Records (EHRs) in Spanish hospitals and Spanish occupying the second place in the ranking of number of speakers, to the best of our knowledge there are no natural language processing tools for medical texts written in Spanish.
This paper presents an approach based on OpenNLP to process natural language texts written in Spanish for information extraction. The main goal is to integrate our development with cTAKES. As cTAKES has been specifically trained for the clinical domain, in this paper we will train the main modules from a general purpose annotated Spanish corpus and an in-house corpus developed with medical documents, testing both on a set of medical documents. Best performance of individual components when tested with medical documents: Sentence boundary detector accuracy = 0.872; Part-of-speech tagger accuracy = 0.946; chunker = 0.909.
