Increasing Performance of Boolean Retrieval Model by Data Parallelism Technique (original) (raw)

Recent Developments in Artificial Intelligence and Communication Technologies

Abstract

Information retrieval (IR) is to identify documents of non-uniform behaviorthat fulfill information requirements from the huge repository (maintained in computersystems). Different models have been defined to retrieve/fetch information. Forexample, the Boolean model, the Statistical model, which focuses on the vector spaceand probabilistic retrieval, and the Linguistic and Knowledge-based retrieval models.The Boolean model is defined as the “perfect match” model. If the queries are notaccurate, they retrieve/fetch some irrelevant documents. This is called the precision (p)rate, which is the proportion of the relevant retrieved documents. The Boolean methodprovides good techniques to elaborate or concise a query. The Boolean method workswell for the search process because of the clarity between the concepts. The Booleanretrieval model processes the queries in which terms of the queries are in the form ofBoolean expressions, that is, in which terms of the user query combined with AND(...
