Medical Concept Embeddings via Labeled Background Corpora
This entry contains the resources used in and resulting from Eneldo Loza Mencía, Gerard de Melo and Jinseok Nam, Medical Concept Embeddings via Labeled Background Corpora, in: Proceedings of the 10th International Conference on Language Resources and Evaluation (LREC 2016), 2016 In recent years, we have seen an increasing amount of interest in low-dimensional vector representations of words. Among other things, these facilitate computing word similarity and relatedness scores. The most well-known example of algorithms to produce representations of this sort are the word2vec approaches. In this paper, we investigate a new model to induce such vector spaces for medical concepts, based on a joint objective that exploits not only word co-occurrences but also manually labeled documents, as available from sources such as PubMed. Our extensive experimental analysis shows that our embeddings lead to significantly higher correlations with human similarity and relatedness assessments than previous work. Due to the simplicity and versatility of vector representations, these findings suggest that our resource can easily be used as a drop-in replacement to improve any systems relying on medical concept similarity measures.
