摘要：Information Retrieval (IR) is concerned with indexing and retrieving documents includinginformation relevant to a user‘s information need. Relevance Feedback (RF) is a class of effective algorithms forimproving Information Retrieval (IR) and it consists of gathering further data representing the user‘s informationneed and automatically creating a new query. Relevance Feedback consists in automatically formulating a newquery according to the relevance judgments provided by the user after evaluating a set of retrieved documents.Finding relevant document is one of the hard tasks. we propose a class of RF algorithms inspired by quantumdetection to re-weight the query terms and to re-rank the document retrieved by an IR system. Informationretrieval (IR) is the activity of obtaining information resources relevant to an information need from a collection ofinformation resources. Searches can be based on full-text or other content-based indexing. Automated informationretrieval systems are used to reduce what has been called "information overload". Most IR systems compute anumeric score on how well each object in the database matches the query, and rank the objects according to thisvalue. The top ranking objects are then shown and IR system return relevant document to the user. The process maythen be iterated if the user wishes to refine the query.
