The use of artificial intelligence in the information retrieval system epoch-making changes in information retrieval system

The purpose of this article is to describes explores ways to solve the difficult problems in the study of the intelligent information retrieval system. This paper first discusses the basic concepts and the structure of the intelligent information retrieval system, the principles of artificial intelligence, the relationship between computer and artificial intelligence, the stage of artificial intelligence research experience, research areas and applications of artificial intelligence, the components and the use of the artificial intelligent information retrieval system in detail. And using the results of the artificial intelligence research, suggests the method to solve the difficulties which are in the areas of natural language understanding, knowledge representation and knowledge acquisition.
