Most word embedding methods are proposed with general purpose which take a word as a basic unit and learn embeddings by words’ external contexts. However, in the field of biomedical text mining, there are many biomedical entities and syntactic chunks which can enrich the semantic meaning of word embeddings. Furthermore, large scale background texts for training word embeddings are not available in some scenarios. Therefore, we propose a novel biomedical domain-specific word embeddings model based on maximum-margin (BEMM) to train word embeddings using small set of background texts, which incorporates biomedical domain information. Experimental results show that our word embeddings overall outperform other general-purpose word embeddings on some biomedical text mining tasks.
