Medical Subject Headings (MeSH) Into Neo4j

To make a knowledge graph, it is useful to have a vocabulary in place, which is called an ontology. The Medical Subject Headings (MeSH) is one such ontology that includes many medical terms and can be downloaded as an RDF file, making it easy to import into Neo4j with neosemantics. Importing MeSH directly into Neo4j takes time due to the large number of nodes and relations. Descriptors, concepts, and terms are closely related in MeSH, where descriptors hold broad categories, concepts provide specific definitions within descriptors, and terms offer synonyms for concepts. Understanding the hierarchical structure is crucial for effective graph analysis, particularly with tree numbers being a more reliable way to establish relationships than broader descriptors. Leveraging MeSH as an ontology can be highly beneficial for constructing medical knowledge graphs, providing valuable insights from medical literature and data.
