Motivation Increasing disease causal genes have been identified through different methods, while there are still no uniform biomedical named entity (bio-NE) annotations of the disease phenotypes. Furthermore, semantic similarity comparison between two bio-NE annotations, like disease descriptions, has become important for data integration or system genetics analysis. Methods The package pyMeSHSim realizes bio-NEs recognition using MetaMap, which produces Unified Medical Language System (UMLS) concepts in natural language process. To map the UMLS concepts to MeSH, pyMeSHSim embedded a house made dataset containing the Medical Subject Headings (MeSH) main headings (MHs), supplementary concept records (SCRs) and relations between them. Based on the dataset, pyMeSHSim implemented four information content (IC) based algorithms and one graph-based algorithm to measure the semantic similarity between two MeSH terms. Results To evaluate its performance, we used pyMeSHSim to parse OMIM and GWAS phenotypes. The inclusion of SCRs and the curation strategy of non-MeSH-synonymous UMLS concepts used by pyMeSHSim improved the performance of pyMeSHSim in the recognition of OMIM phenotypes. In the curation of GWAS phenotypes, pyMeSHSim and pr...Continue Reading
