Query Expansion in Information Retrieval Systems using a Bayesian Network-Based Thesaurus

  title={Query Expansion in Information Retrieval Systems using a Bayesian Network-Based Thesaurus},
  author={Luis M. de Campos and Juan M. Fern{\'a}ndez-Luna and Juan F. Huete},
Information Retrieval (IR) is concerned with the identification of documents in a collec­ tion that are relevant to a given information need, usually represented as a query contain­ ing terms or keywords, which are supposed to be a good description of what the user is look­ ing for. IR systems may improve their effect­ iveness (i.e., increasing the number of relev­ ant documents retrieved) by using a process of query expansion, which automatically adds new terms to the original query posed by… CONTINUE READING
