With the more and more amount of Web Services appears, the quality of services becomes lower and lower. There is a question which must be solved urgently, that is how to compose dynamically the Web Services effectively to satisfy people's demand. Based on describing the disadvantages of the traditional semantic Web Services description module, this paper analyzes the concept, basic elements and categories of Web Service combination, constructs a semantic dynamic service combination module, and explains shortly several kinds of Qos demands supporting Web Services.

This paper built an integrated network information service platform for group of graduate candidates, and integrated the information resources on the the evaluation of personnel and educational by web technology, and provided the information service about personal diagnosis and consulting, exploited the values of information on evaluation fully. This paper constructed an evaluation model, which implemented the automatic matching of the user's psychological characteristics (the object of personnel evaluation) and the subjecs and professions (the object of educational evaluation).

At the basis of analyzing the basic structure and current application of the Semantic Web Service, we built digital library system integration model based on Semantic Web Service. Detailing the realization process of the entire model, the paper focuses on the two main modules: the main module of digital library system integration processing and the main module of digital library system function query. The model is the effective integration of digital library system resources to create a centralized, united digital library system, and to make the query up to semantic level. It enhances the overall operation and service performance of digital libraries.

25 Statistical Reports on the Development of Chinese Internet and 5 Survey Reports on the Chinese Network Information Resources published by China Internet Network Information Center are taken for analysis. From the point of view of domain name, web site and web page respectively, the paper conducts detailed analysis on the growth of basic network information resources in China. The statistical analysis on network information indicates expandness and logic growth on Chinese network information resource. Causes and current problems in change processes of Network information resources through the past 13 years are explored.

Stating the "information island" of e-government construction and so on, proposing the digitization of government resources-related issues, this paper constructs the overall model of the digitization of government resources. In the model, we gave a detailed analysis of the abstract description of the process of their resources, built a SAN-Storage Area Network strategic framework, made redundant SAN-Storage Area Networks Strategic Framework. Finally against the particularity of government resources, we built an inter - language retrieval model to achieve its efficient retrieval.

This paper discusses the five emergency service functions of government websites and analyzes several defects existed in the emergency service functions of China's government websites. Combining the experience of U.S. government website, some suggestions are provided to improve the emergency services functions of China's government websites.

Search engine is an important tool for users to access network information resources. However, a large number of duplicate and near-duplicate pages added user's burden. Currently, search engines only remove duplicate pages, but have not yet any effective strategies in detecting and disposing near-duplicate pages. This paper analyzed the existing algorithms to select an appropriate algorithm to detect near-duplicate pages, and optimized the disposing strategy to ensure that near-duplicate pages would not take up too much space in search results while being used effectively. These will allow users to retrieve needed information more easily.

This paper studies on the hot papers of clinical medicine field based on ESI (Essential Scientific Indicator) database, from January 1, 1998 to December 31, 2008. The data about these 324 papers are analyzed by the authors from the aspects of publishing time, country/territory, institution, journal, and so on. In order to discover the hotspots in the clinical medicine field in the global world, the methods of multi-dimension analysis, cluster analysis, pajek visualization are used and 54 pieces of papers are chosen based on citation of the 324 papers. The result shows that cancer is the research hotspot, and the correlativity of the title in the clinical medicine field in the global world can be shown by the cluster analysis. This study provides information for the researchers and scholars in the clinical medicine field, significant and specifically functional to them.

Web has become the major tool of e-commerce for the last ten years and it requires Internet corporations to provide personalized services by tracking and analyzing users' visiting patterns. Web data analysis system (WDAS) is a necessary tool supporting the Web data mining and knowledge discovery (DM & KD) process. However, in the past, research on DM & KD always focused attention on algorithm of a specific mining, without the analysis on the establishment of a whole system. In this paper the authors demonstrates fundamental goals of WDAS design. After an introduction about the basic function of WDAS, the authors present the structure of WDAS which consists of users' interface agent, data preprocessing agent, data mining agent, pattern evaluation agent, models and knowledge base and specific criteria for assessment of WDAS.

This paper makes a bibliometric study of the articles on material science in ESI with a special emphasis on the distribution of countries, institutions, journals and scientists of high productivity and impact. It also analyzes the journals and scientists with highly cited papers and hot papers on material science. Finally, the co-citation analysis on the highly cited authors is conducted by SPSS so as to provide the hotspots and scientists' clusters on material science in recent 11 years. And some conclusions are got in this study.

The researches on supply chain are mainly about the conjunction mechanism and efficiency in Integrated supply chain to enhance its competitiveness and the cooperation between its members. But most of those belong to the standard finance field, and few about the factors of human psychology. We studied the satisfaction degree models of customer with mental account based on the customer satisfaction degree (CSD) model and found they are simplified, not reasonable and inaccurate. This paper presents a CSD model based on artificial psychology, which quantify exact customer psychology using cognition and artificial psychology methods, and describes an optimization model of the ISC bi-level distribution network based on artificial psychology.

Nowadays customer preference has aroused concerns in customer satisfaction researches of e-learning, but specifications of user psychology can not been stated clearly in existing tools. This paper describes an individual-centered e-learning tool taking into account the full spectrum of Web mining techniques and activities, presents a multi-agents architecture based on artificial psychology techniques, which will make the e-learning process both adaptable and dynamic, and hence up-to-date. Knowledge base techniques are used to support the adaptation of agents' cycle, and artificial psychology techniques and beliefs techniques are combined to manage preference and experimental knowledge and to realize more effective and more precise knowledge management.
