LexAccess is a lexical access tool in the SPECIALIST Lexicon family. LexAccess is developed to integrate with LexBuild and provide access to the information from the SPECIALIST lexicon.
LexCheck is a software package to check and auto-correct the syntax and contents of Lexical record(s) in the LEXICON based on the technical report of "The SPECIALIST LEXICON".
The SPECIALIST lexical tools are a set of JAVA programs designed to help users manage lexical variation in biomedical text. The tools use information from the SPECIALIST lexicon and other data to generate lexical variants of words or terms appropriate for use in indexing and other NLP applications.
Consult the MetaMap page to learn about the myriad ways to use this tool.
The RxNorm Current Prescribable Content is a subset of currently prescribable drugs found in RxNorm. We intend it to be an approximation of the prescription drugs currently marketed in the US. The subset also includes some frequently-prescribed over-the-counter drugs.
The subset includes only the active RxNorm normalized names, codes (RxCUIs), attributes, and relationships, as well as the FDA structured product label drugs and ingredients. It does not include data from any of the other 10 RxNorm data providers, such as First DataBank, Micromedex, or the Veterans Administration. We also removed suppressed and obsolete data.
The National Library of Medicine provides this subset without any licensing restrictions. You do not need to log into the UMLS Terminology Services to access the subset.
The RxNorm Prescribable API is a web service for accessing the RxNorm Current Prescribable Content from your program.

Use UMLS resources in developing effective natural language processing systems that provide semantic interpretation to support innovative information management applications in the biomedical domain. The SKR_API provides access to the entire suite of SKR tools including MetaMap, Medical Text Indexer (MTI), and SemRep, and allows programmatic access to the SKR Batch and Interactive facilities allowing users to submit data and receive results from within their own application(s).
The Sub-Term Mapping Tools (STMT) is a generic tool set that provides comprehensive sub-term related features:
- to find all sub-terms
- to find all prefix sub-terms
- to find the longest prefix sub-term
- to find all sub-term patterns
- to find all permutations of synonymous sub-term substitutions (query expansion)
