Description

Embeddings This repository contains the word embeddings generated from biomedical Spanish texts corpora. Corpus detail The corpus was gathered from Spanish biomedical texts from different multilingual biomedical sources: IBECS (Spanish Bibliographical Index in Health Sciences): corpus that collects scientific journals covering multiple fields in health sciences. Contains titles and abstracts from 168,198 records in English and Spanish. SciELO (Scientific Electronic Library Online): corpus gathers electronic publications of complete full-text articles from scientific journals of Latin America, South Africa, and Spain. Contains titles and abstracts from 161,710 records in English and Spanish. Pubmed: free search engine used to access the MedlineNLM (https://www.ncbi.nlm.nih.gov/pubmed/). Contains titles and abstracts from 127,619 records. MedlinePlus: corpus with health topics, drugs and supplements, laboratory test information, and medical encyclopedia texts contains 7,033 articles in English and Spanish. UFAL Medical Corpus is a collection of parallel corpora of medical and general domain texts. All corpus data files can be found in the next link: http://temu.bsc.es/mespen/ Pre-trained Models FastText We used the FastText (Bojanowski et al., 2016) implementation to training our word embeddings using the preprocessed Spanish Biomedical corpus (FastText-SBC). Moreover, we trained a concept embedding model replacing biomedical concepts in the Spanish Biomedical corpus with their unique SNOMED-CT Spanish Edition iden-tifier (SNOMED-SBC). We used the PyMedTer-mino library (Lamy et al., 2015) for concept indexing using full-text search and fuzzy search with threshold.
