The Ontology Tools Package (OTP) allows users to interact with a local UMLS knowledge collection instance, diagnostic databases, and text report databases. Users can query OTP with a keyword or textual phrase, which is then mapped to one or more concept codes derived from text mining approaches informed by the UMLS and using MMTx. Once users finalize a set of targeted search concepts, text reports that contain those concepts are queried and returned. Users can also retrieve ICD9-CM codes that correspond to their query keywords and use those codes to query tables containing structured data.
