MMTx (MetaMap Technology Transfer)

Home

---

MMTx is an effort to make the MetaMap program available to biomedical researchers in a generic, configurable environment. MetaMap maps artibrary text to concepts in the UMLS^® Metathesaurus^®; or, equivalently, it discovers Metathesaurus^® concepts in text.

With this software, text is processed through a series of modules. First it is parsed into components including sentences, paragraphs, phrases, lexical elements and tokens. Variants are generated from the resulting phrases. Candidate concepts from the UMLS Metathesaurus are retrieved and evaluated against the phrases. The best of the candidates are organized into a final mapping in such a way as to best cover the text.

Documentation on MetaMap and associated research can be found at the Semantic Knowledge Representation (SKR) Research Page
