A Study On Information Niche And Its Evolution Model On Information Service Platform

With the information age, people gradually realize that the information ecology has become a more and more important and complex issue involved in many areas, the development of information ecology infiltrates gradually other areas of science, promotes the development and update of the related science concepts, and particularly in information management concepts. At the same time, the study on the application of information theory provides a great practical significance in explaining ecological phenomena, keeping the balance of information ecology, and achieving coordinated development between information environment and human society. Therefore, it is highly concerned about the ecological theory and in-depth research, and its applications have become an important international academic research. In addition, the information service platform has a huge advantage in information integration and information sharing, and it has become an important direction, therefore, the study on information management for information service platform is becoming hot. The paper applies information ecology in information service platform, and researches information ecology and its evolution model of information service platform.The paper studies firstly the information service platform and information ecology, summarizes the theories of niche and information niche, and analyzes its ecological characteristics. By absorbing other studies on information niche, the paper analyzes the intension, extension, overlap of information niche in information service platform, and studies its potential influences on information service platform. Based on the nice overlap model, the paper sets up the model of information nice overlap for information service platform, and the study not only expands the ecological theory, but also opens an information niche applications, in particular the use of the model analysis for the information service platform niche evolution theory, the optimization for information service platform on information niche evolution. Then, the model can judge the merits of information service platform in the, finding the defects during the process to make a better information service management strategies and service strategies, which promote the information service platform efficiencies and effectiveness. The paper has an important practical significance.
