Identification of Synonyms Using Definition Similarities in Japanese Medical Device Adverse Event Terminology

Japanese medical device adverse events terminology, published by the Japan Federation of Medical Devices Associations (JFMDA terminology), contains entries for 89 terminology items, with each created independently. It is necessary to establish and verify consistency these map them efficiently accurately. Therefore, developing an automatic synonym detection tool important concern. Such tools edit distances distributed representations have achieved good performance in previous studies. The purpose this study was identify synonyms JFMDA evaluate accuracy using algorithms. A total 125 definition sentence pairs were from as baselines. Edit (Levenshtein Jaro–Winkler distance) (Word2vec, fastText, Doc2vec) employed calculating similarities. Receiver operating characteristic analysis carried out detection. comparison accuracies algorithms showed that distance had highest sensitivity, Doc2vec DM specificity, Levenshtein value area under curve. makes it possible obtain high predicting terminology.
