Probability Based Model for Information Retrieval System

Information retrieval system is designed with the objective to provide the essential utilities, tools, and techniques that assist a user to perform various tasks in finding useful information and knowledge. However, the present indexing techniques have not able to improved retrieval results, because they only contain the inference information with lack of semantics. Therefore the need for research activities in information retrieval system & enhancements by developing a precisions and intended techniques for the support of heterogeneous infrastructure is apparent. To accomplish this task we proposed Semantic Information Retrieval system that gives an innovative direction for scientific research and pushing information technology to toward making the meaning information and exploits some mathematical and probability techniques to automatically extract valuable information from the particular system. Mathematical model of SIR system is based on the standard principle of probability, where documents ranking is based on their quality and calculates the numerical weight of each document on the basis of citation analysis.
