These limitations include missing semantic information for terms, single-document retrieval, and lack of contextual ranking. Current research in tackling these constraints deals with concept-based information retrieval User Query Search and search. Mine, Search, Transform (MiSTeRy) Visualizer is a concept-based search application tion ssocia which utilizes the state-of-the-art research for incorporating semantic techniques in the Article Name Refine Results hasA domain of retrieving evidence-based literature from PubMed. The articles in PubMed are Score Authors, Publication Details Semantic Types Semantic Type, Concepts Type 1 indexed with MeSH (Medical Subject Headings) concepts. The Medical Subject Headings Type 2 Type 3 Semantic Type2 (MeSH®) thesaurus is a controlled vocabulary produced by the U.S. National Library of Medicine Article Name (NLM) and used for indexing, cataloging, and searching for biomedical and health-related Score Authors, Publication Details Semantic Concepts [370] Semantic Type3 Semantic Type, Concepts Concept 1 [500] information and documents. We have utilized the MeSH indexing of PubMed database to Sub Concept 1 Semantic Type1 improve the precision/recall ratio for the retrieved documents. The user of the system is a Sub Concept 2Ranked Articles Article Name Sub Concept 3 [100] researcher who has a set of terms and is looking for the literature relevant to those terms. The Score Authors, Publication Details Concept 2 Concept 1 Semantic Type, Concepts query provided by the user is expanded using the NLMs MetaMap tool. MetaMap uses UMLS Ranking Criteria Query Relevance Metathesaurus and Semantic Network to employ knowledge-intensive approach for identifying Article Name Concept 1 [150] nouns and corresponding scored concepts and semantic types from the provided text. The Score Domain Relevance Authors, Publication Details Query + Domain Relevance Semantic Type, Concepts Concept 1.1 [70] retrieved concepts are used to perform a query on PubMed to retrieve a set of articles. These Authors Concept 1 [50] Concept 1.2 [40] articles are ranked based on the commulative MeSH concept scores (query relevance) as well as Author 1 Article Name Concept 1.1 [30] on the basis of frequency of occurrence of a concept in retrieved set vs. the whole of PubMed Score Author 2 Authors, Publication Details Author 3 Semantic Type, Concepts Concept 1.2 [20] (domain relevance). Moreover, the concepts and semantic types of the MeSH terms in the Country Concept 2 [30] retrieved resultset are used to provide user with an option of refining (specializing/ Article Name Country 1 generalizing) the search and present a graphical summary of the results. Score Authors, Publication Details Country 2 Semantic Type, Concepts Country 3 Refine Concept 10 [120] Keywords: Keyword-based search, Concept-based search, MeSH, semantic search.
