Finding semantic similarity between short biomedical texts, such as article abstracts or experiment descriptions, may provide important information for health researchers.This paper presents a method for calculating text similarity in the biomedical context.The method implements a pairwise concept semantic similarity measure that uses concept definitions and ontology structure.The respective results have demonstrated an improved performance in comparison with a previous version of the method using lexical-based measures as similarity function, as well as with other alternative tools for measuring text similarity.
