F., García Figuerola, L. C., Alonso Berrocal, J. L., Rodríguez Vázquez de Aldana, E. (2005). Reformulation of queries using similarity thesauri. "Information Proccesing and Management", 41(5). 1163-1173 http://hdl.handle.net/10366/56134 One of the major problems in information retrieval is the formulation of queries on thepart of the user. This entails specifying a set of words or terms that express their informationalneed. However, it is well-known that two people can assign different terms to refer tothe same concepts. The techniques that attempt to reduce this problem as much as possiblegenerally start from a first search, and then study how the initial query can be modified toobtain better results. In general, the construction of the new query involves expanding theterms of the initial query and recalculating the importance of each term in the expandedquery. Depending on the technique used to formulate the new query several strategies aredistinguished. These strategies are based on the idea that if two terms are similar (withrespect to any criterion), the documents in which both terms appear frequently will also berelated. The technique we used in this study is known as query expansion using similaritythesauri. eng Attribution-NonCommercial-NoDerivs 3.0 Unported Similarity thesaurus Query expansion Information retrieval Term weighting Thesaurus Reformulation of queries using similarity thesauri info:eu-repo/semantics/article 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 URL https://gredos.usal.es/bitstream/10366/56134/1/DIA_Reformulationqueries.pdf File MD5 ebb214af092728f6ee47415f42ce4b6f 157725 application/pdf DIA_Reformulationqueries.pdf URL https://gredos.usal.es/bitstream/10366/56134/4/DIA_Reformulationqueries.pdf.txt File MD5 f0460847b19613c17e65c884cf5601b3 30721 text/plain DIA_Reformulationqueries.pdf.txt
