Study Results from University of Vigo Update Understanding of Life Science Research (Study of query expansion techniques and their application in the biomedical information retrieval)

By a News Reporter-Staff News Editor at Life Science Weekly -- A new study on Life Science Research is now available. According to news reporting from Ourense, Spain, by NewsRx journalists, research stated, "Information Retrieval focuses on finding documents whose content matches with a user query from a large document collection. As formulating well-designed queries is difficult for most users, it is necessary to use query expansion to retrieve relevant information."

The news correspondents obtained a quote from the research from the University of Vigo, "Query expansion techniques are widely applied for improving the efficiency of the textual information retrieval systems. These techniques help to overcome vocabulary mismatch issues by expanding the original query with additional relevant terms and reweighting the terms in the expanded query. In this paper, different text preprocessing and query expansion approaches are combined to improve the documents initially retrieved by a query in a scientific documental database. A corpus belonging to MEDLINE, called Cystic Fibrosis, is used as a knowledge source."

According to the news reporters, the research concluded: "Experimental results show that the proposed combinations of techniques greatly enhance the efficiency obtained by traditional queries."
