A Study On Internet Information Retrieval And Developing Trend

With the rapid development of Internet, the conflicts between huge digital information on Internet and people' s capability of acquiring information is more and more remarkable. So it is urgent and practical to study two Internet information retrieval techniques and their developing trends. The paper gives a study on the Internet information retrieval including its working reason, retrieval techniques and practical tools and their developing trends. The text comprises 6 parts:The first part is a review, It mainly elaborates related concept in this field such as information retrieval techniques and their characters, the evaluation of information retrieval result and so on.The second part discuss the basic Internet information retrieval techniques, such as information push-and - pull technique, data mining technique, information filtering technique, natural language processing technique and so on. This part is to ascertain the technology supporting Internet information retrieval, which lays the base for predicting the future development of Internet retrieval.The third parts discuss an important tool for Internet information retrieval-search engine. Researching from the mechanism of different kinds of search engines. In the part, is generalizes the search engines' functions and classifies them scientifically so as to find out their developing reason, which is a innovation point.The forth part discusses another information retrieval technique-content-based retrieval techniques. It mainly the studies the static graphic retrieval and video retrieval. There are somewriter' s new view when analyses the static graphic retrieval. Content-based information retrieval is mainly used for multimedia information retrieval, the study on it is to explore the better tools of multimedia information retrieval.The fifth part analyses the limitations of Internet information retrieval tools when retrieve text and multimedia information, which helps to find out the future direction of the Internet information retrieval.The sixth part predicts the developments trend of Internet information retrieval from the aspects of retrieval mechanism, retrieval effect, intelligent retrieval, multimedia information retrieval and so on. It concludes that we should develop newer retrieval techniques, make the searching more completely and accurately, and improve the visualization and human nature of the retrieval access.Combining the latest information technology and making a forecast for the development of internet information retrieval techniques from all levels of retrieval techniques is another innovation point in the appear.
