分布式协作模型及应用研究

With the development of the Web technology,the application environment has acquired many new characters such as dynamic, openness,distribution and information uncertainty.The processing mode of application systems is more complicated than ever.For example,it requires application systems to have more community processing ability,interactive ability,distributed processing ability and collaborative ability.Accordingly the research and development of the computer application system transited from client/server information processing system into distributed collaborative processing system based on Web.Especially in the environment where the information and resources are highly distributed,the accomplishment of complicated tasks is dependent more on the resources coordination,information sharing and coordinator collaboration.The collaboration is one aspect of the group behavior and its goal is to provide a optimal method to utilize the resource through the information interaction and to solve the task which couldn't be accomplished by each coordinator alone and get the more total benefits than the sum of each benefit.The collaboration problem is the important one for distributed tasks processing.This paper surveys,the research and application status of distributed collaborative models and several representative architectures of distributed collaborative processing are proposed.However,the existing problems and the future researching direction are presented.     

Web Block Extraction System Based on Client-Side Imaging for Clickable Image Map

We propose a new Web information extraction system. The outline of the system and the algorithm to extract information are explained in this paper. A typical Web page consists of multiple elements with different functionalities, such as main content, navigation panels, copyright and privacy notices and advertisements. Visitors to Web pages need only a little of the pages. A system to extract a piece of Web pages is needed, our system enables users to extract Web blocks only by setting clipping areas with their mouse. Web blocks are clickable image maps. Imaging and detecting hyperlink areas on client-side are used to generate image maps. The specialty of our system is that Web blocks perfect layouts and hyperlinks on the original Web pages. Users can access and manage their Web blocks via Evernote, which is a cloud storage system. And HTML snippets for Web blocks enable users to easily reuse Web contents on their own Web site.     

The Data Warehouse Model Based on Web Service Technology

This paper analyses the advantages of comhining Web service and data warehouse, then introduces a distributed data warehouse model based on Web service. It also introduces some features of Web services and data warehouse, Web service is a bridge, which can link different models, different operation systems and different program languages. With the development and application of Web service technology, the current operation of design and application will shift to develop and make use of Web service. Web service will matke ＂software as service＂ come true and finally let people think software is of great value, and its value can be embodied and transferred on the web. As a decision supporting system, data warehouse provides a solid plattbrm formed by current data and past data. Using this platform, companies can make a series of commerce analysis. This work combines the Web service and data warehouse, extends data warehouse＇s network ability. Then, Companies Corporation and individual can obtain information conveniently.     

Web SCADA System Architecture Design

When constructing SCADA （Supervisory Control and Data Acquisition） system, the main problems that need to be solved are the system＇s easy-extension, the system＇s easy-maintain and the unifying of the management information system, The effective way to solve these problems is designing SCADA system based on B/S architecture by Web technology. This paper provides a kind of SCADA system frame based on Web technology and mainly describes the structure of the software in the Web server in this frame.

In the information time,the information technology and industry plays more and more important role in development of economy,promoting the world to be unified and emphasizing the globalization through such tendency of their own.The IT application area also becomes larger and diverse through the mergence of multiple disciplines and multiple domains.IT industry demands the inter-disciplinary talent,who are believed to be industrialized,internationalized,and equipped with multi-disciplinary and inter-domain knowledge,and the ability of international competence.Facing the challenge of the new globalization tendency of international industry especially the IT and software industry,universities keep make great efforts to provide qualify graduates to fulfill the demand of industry.This paper introduces a novel joint Master programme which aims at establishing an international education system and platform.The schema,the characteristics,the execution principles are discussed wishing to share our practice and experience with our education colleagues.     

Distributed and cooperative information retrieval on the World Wide Web

A masss of heterogeneous,distributed and dynamic information on the World Wide Web(the Web) has resulted in “information overload“ .It‘s an important and urgent reserach issue to provide users with effective information retrieval service on the Web.Web search enginees attempt to solve this problem,yet their effect is far from satisfying.In this paper,a distributed and cooperative strategy for information retrieval on the Web is proposed to substitute the centralized mode adopted by the current search engines.Then a new information retrieval system model IRSM is presented.which supports the retrieval of metadata about web documents and uses Z39.50 standard protocol to unify the heterogeneous interfaces of uments and uses Z39.50 standard protocol to unify the heterogeneous interfaces of different systems.Based on that,a distributed and cooperative information refieval framework,called DCIRF,is designed to help users in fast and effective information retrieval on the Web.
