چکیده
In this paper I provide some important information search models. This covers traditional and novel methods. An Information Retrieval (IR) System, which only returns documents containing the keywords in user query in high frequency, does not satisfy the user’s information need. Infact, the user is more concerned with receiving the documents, contain the information he needs than with receiving data which satisfy a given query. This paper will present the classical model as the background and then focuses on the new models : Latent Semantic Indexing(LSI) and Correlation Method.
