Whereas, with traditional EAI solution, it is difficult to efficiently link the different proprietary applications and data sources, and difficult to enable the system to rapidly identify and respond to changes in the dynamic business environment. In order to solve these problems, this paper uses the Web Services technology for EAI. This paper discusses the traditional EAI technologies and the bottlenecks for applications integration, also elaborates the Web Services technology and the advantages suited for applications integration. Therefore, the model of EAI with Web Services (EAIWS) is proposed to efficiently implement the integration of diverse applications and systems within or between the enterprises. With EAIWS, this paper provides an example to show how the application system works. This paper also discusses the advantages of EAIWS.展开更多

In this paper, we present a pre-fetching model based an the hidden Markov model, which mines the later information requirement concepts that the user's access path contains and makes semantic-based pre-fetching decisions. Experimental results show that our schcme has better predictive pre-fetching precision.展开更多

Existing results pay more attention to studying the knowledge diffusion in one discipline or among different fields, while studies on the dynamic process of the academic innovation diffusion remain rare. Present study provides a valuable reference not only for colleges and universities to construct the disciplines, organize the interdisciplinary research, tackle the key problems, select the research topics, grasp the subject frontier and trend, but also important for the scientific research management departments to plan strategy and policy, and evaluate projects and research. This study establishes a sequential network of knowledge diffusion, draws the diffusion curve, and measures the speed and acceleration. The subject distribution as well as the delay and diffusion curved in different subjects have been studied. Besides, the diffusion strength and the information interactive mode have been analyzed. This paper also identifies the main path, the main path component, and the key nodes with the definition of the diffusion span, the diffusion speed, the diffusion acceleration, the diffusion strength and the diffusion delay. This paper integrates different methods and analysis dimensions, and finally concludes the general methods and steps to analyze the diffusion process.展开更多
