Query expansion using the UMLS Metathesaurus
Recent work has demonstrated the importance of query expansion for improving retrieval effectiveness when applying statistically-based systems to MEDLINE citations. The research has suggested the use of retrieval feedback for enhancing the original text of users' queries. As an alternative method of query expansion, we propose the use of the MetaMap program for associating UMLS Metathesaurus co...
متن کاملAssessing thesaurus-based query expansion using the UMLS Metathesaurus
OBJECTIVES Assess query expansion using thesaurus relationships and definitions in the UMLS Metathesaurus for improving searching performance. METHODS The queries from a MEDLINE test collection (OHSUMED) were expanded using synonym, hierarchical, and related term information as well as term definitions from the UMLS Metathesaurus.

متن کاملQuery Architecture Expansion in Web Using Fuzzy Multi Domain Ontology
Due to the increasing web, there are many challenges to establish a general framework for data mining and retrieving structured data from the Web. Creating an ontology is a step towards solving this problem. The ontology raises the main entity and the concept of any data in data mining. In this paper, we tried to propose a method for applying the "meaning" of the search system, But the problem ...
متن کاملAnnotating Medical Forms Using UMLS
Medical forms are frequently used to document patient data or to collect relevant data for clinical trials. It is crucial to harmonize medical forms in order to improve interoperability and data integration between medical applications. Here we propose a (semi-) automatic annotation of medical forms with concepts of the Unified Medical Language System (UMLS). Our annotation workflow encompasses...
متن کاملImproving UMLS Metathesaurus Query Expansion Based on the Query Specificity and Length
Query expansion is commonly used in health information retrieval. By adding synonyms and related terms using Unified Medical Language System (UMLS) Metathesaurus, query expansion can help users find more relevant information. In this paper, we studied how query specificity (the specificity of a query term) and query length (the number of words in a query term) influence the effectiveness of gen...
