Using WordNet synonym substitution to enhance UMLS source integration

Using WordNet synonym substitution to enhance UMLS source integration

OBJECTIVE Synonym-substitution algorithms have been developed for the purpose of matching source vocabulary terms with existing Unified Medical Language System (UMLS) terms during the integration process. A drawback is the possible explosion in the number of newly generated (potential) synonyms, which can tax computational and expert review resources. Experiments are run using a synonym-substit...

Using WordNet to Improve the Mapping of Data Elements to UMLS for Data Sources Integration

Each biomedical system has its own way of naming the pieces of information it contains, i.e., of defining its data elements (DEs). Integrating DEs facilitates the integration of biomedical resources. However, the mapping of DEs to the UMLS is ambiguous in many cases, when any correspondence is found at all. We propose to evaluate the potential contribution of a more general terminology: WordNet...

Scalability of Piecewise Synonym Identification in Integration of SNOMED into the UMLS

Synonym identification during source terminology integration into the Unified Medical Language System (UMLS) is a labor-intensive task needed for every new release of the source. The piecewise synonym (PWS) methodology was previously used for the integration of a small source. The goal of this paper is to determine whether the piecewise synonym methodology with two control parameters scales to ...

Piecewise Synonyms for Enhanced UMLS Source Terminology Integration

The UMLS contains more than 100 source vocabularies and is growing via the integration of others. When integrating a new source, the source terms already in the UMLS must first be found. The easiest approach to this is simple string matching. However, string matching usually does not find all concepts that should be found. A new methodology, based on the notion of piecewise synonyms, for enhanc...
