Semantic transference for enriching multilingual biomedical knowledge resources

María Pérez, Rafael Berlanga
2015 Journal of Biomedical Informatics  
Biomedical knowledge resources (KRs) are mainly expressed in English, and many applications using them suffer from the scarcity of knowledge in non-English languages.  ...  The goal of the present work is to take maximum profit from existing multilingual biomedical KRs lexicons to enrich their non-English counterparts.  ...  The work was supported by the R&D project TIN2014-55335-R from the Spanish Ministry of Economy and Competitiveness (MINECO) and by the UJI INNOVA project 13I346 in collaboration with ActualMed.  ...

Machine Translation for Entity Recognition across Languages in Biomedical Documents

Giuseppe Attardi, Andrea Buzzelli, Daniele Sartiano
2013 Conference and Labs of the Evaluation Forum  
We report on our experiments for the CLEF 2013 Entity Recognition Challenge. Our approach is based on a combination of machine translation and NE tagging techniques.  ...  The model is used for tagging entities in sentences in the target language with the proper semantic group and the entity dictionary is used for associating CUIs to each of them.  ...  Partial support for this work was provided by project RIS (POR RIS of the Regione Toscana, CUP n° 6408.30122011.026000160).  ...

Multilingual Named-Entity Recognition from Parallel Corpora

Andreea Bodnari, Aurélie Névéol, Özlem Uzuner, Pierre Zweigenbaum, Peter Szolovits
2013 Conference and Labs of the Evaluation Forum  
We present a named-entity recognition (NER) system for parallel multilingual text. Our system handles three languages (i.e., English, French, and Spanish) and is tailored to the biomedical domain.  ...  Each language model benefits from the external knowledge extracted from biomedical and general domain resources.  ...  Our data consists of parallel multilingual corpora in English (en), French (fr), and Spanish (es).  ...
