What is the MLP?
The MLP — Medical Language Processor — is a system that
transforms free-text clinical documents into an XML
structured representation of the information in the
documents. Document sentences are parsed,
further processed to eliminate ambiguities, and mapped into
medically labeled structures, called
Information Format Units (IFUs). The IFUs are enriched
by the addition of medical knowledge tags drawn from
the Structured Health Markup Language (SHML). In this form they
become Health Information Units (HIUs), the basic unit of description
in the final representation. Processed documents are installed in
a clinician-oriented viewer to provide users
selective access to textual information needed for patient
care, or they can be used in other applications.
More recently XML has been incorporated into the system in two ways: tagging lexical entries with their specific medical content (using a Medical Tag Hierarchy), and incorporating the results of tagging into an XML representation of the parsed documents. The tags serve for retrieval and display in terms of categories familar to physicians. |
