This paper reviews what CSDL has done in resources building of science journals and services providing, summarizes current problems of integration of journal system and services, after referring to international related projects and analyzing current status and development of CSDL, we turn to construct an integrative journal catalog system with scenes sensitive function. This paper introduces the aim and idea of system, also including the details of the design and implementation. Finally, some problems still be here and possible anticipation.

This paper analyzes the condition of log recording in digital library, finds out the existing problems, and advances a log schema based on XML which is applied in the experiment system.

This paper specifies the advantags of NXD database over RDBMS in storing and using DC metadata. It also puts foward a prototype system which store and use DC metadata based on a NXD database.

Through analyzing a lot of current Ontology reasoners in detail, this paper concludes a general system structure for Ontology reasoners. After introducing three typical Ontology reasoners (Pellet, Racer, FaCT++), it proposes and implements a test plan for Ontology reasoners from the system, user and developer’s point. The experiment results show that the test plan is feasible and effective. At last, the paper analyzes the disadvantages of current Ontology reasoner and gives some ideas on Ontology reasoners’ future development.

This paper describes the design and implementation of the Electronic Theses and Dissertations System of Chinese Academy of Sciences based on KOS, briefly completing the analyzis and design the system function and user interface, and introducing the project feasibility plan.

This paper provides a scheme of CAIP adopting knowledge organization based on Ontology. CAIP will organize the information of literature, project, institute and experts in the field of AIDS and provide the strong related retrieval function. This paper emphasizes on the way of organizing the different information and their relationships and realizes them using the Protégé software.

This pager introduces the project design and implementation of Integrated and Agent Retrieval System for Domain Digital Resource of Diseases/Diagnoses. Based on domain Ontology of disease/diagnoses, the building  and application of Ontology in this project will service for agent retrieval and knowledge organization. It introduces the application of information visualization technology in human interface design through analysis of users and users’s typical task.

The paper analyses the difficulty in the current information retrieval systems and expounds the problem which are in need of solution urgently. It compares the current Intelligent Information Retrieval (IIR) models and propose the novel IIR model, i.e. Knowledge Space- based Model (KSM). It provides the frame and architecture of KSM-IIR. Some key issues of the model are proposed.

This paper presentes a new information retrieval framework, which combined Case-Based Reasoning (CBR) and Ontology through the way of using the Ontology to annotate Web pages and design case, also using the CBR to reason about Web page content. The paper gives a system application to tourism as example.

This paper discusses the method of building ancient agricultural book Ontology at the view of data selection, building method and design. At the same time, this paper realizes the query and browsing of ancient agricultural book Ontology.

Facing too much results returned by different search engines, this paper designs a meta-search in order to fully utilize the results. It introduces the basic structure of meta-search and methods of results merging. And employs the techniques of statistics to study the relevance between title and page content, relevance between abstract and page content, and then fixes the weights of title and abstract when judge the relevance of search results. The experiment proves the improvement of average veracity comparing with the member search engines.

This paper discusses  the method of  sorting  the search result automatically by formal concept analysis, so that the user can make a better use of the result and the search efficiency is improved.

This paper puts forward a kind of novel distributed intelligent recommendation system based on mobile agent and Web services and constructs the architecture of the system. Meanwhile the paper narrates the workflow of the system. Finally the paper particularly explains the implementing algorithms of main functions of the system including the global implementing algorithm, clustering algorithm and suggestion algorithm.

The paper analyzes the topic-focused features in and of Web pages. Then a topic-focused information acquisition system is described. Finally several factors which can affect the gathering quality are discussed.

This paper talks about the Internet hot spot——Wiki which bases on the Web2.0, and illustrates the knowledge creation process through the Wiki technology. Applies the Brooks formula to contrast the information and knowledge, analyzes the knowledge creation and knowledge innovation systematically. Then puts forward some suggestions to avoid disadvantage effect about wiki that is possible to be misused as other technology.

The paper analyzes present usage of library RFID-UID， and proposes a new standardization precept of RFID-UID encoding for library application

The process of modeling and developing library  software with customized RUP （Rational Unified Process） and UML is presented, and its practicality is validated through the implementation of a library information management system based on B/S. The process is now being used for the development of a Chinese-Thesaurus-based Ontology KB Constructing and sharing system sponsored by National Social Science Foundation of China.

This research attempts to use respectively the discriminant analysis of statistical method and the decision tree of data mining technology to establish model in the medical record data, then carries on the comparative analysis of the classified coincidence rate, model accuracy and model precision，the results indicate that the decision tree holds the obvious superiority.

A Web application method is proposed, which builds ActiveX DLL component with Visual Basic to acquire the image size. It meets the demands of image size in Web application. This paper discusses design method and steps of server-side component in detail, and the programming codes are also described.

The text automatic clustering has been put forward and studied in application. This paper proposes a text clustering framework by coalescent the HAC and K-Means clustering algorithm, and evaluates this framework in an experiment.

Based on the experiences and rules that summarized from the science information consulting work, Tsinghua University Library apply the computer-assisted technology to the science information consulting process. A unique computer-assisted software application named WordSnap is developed to assist the consultant to finish the consulting works. The major functions of WordSnap includes: the search formula conversion between different databases, the attachment file content validation, the attachment file output format check. By using the assistant software, the consultant can save plenty of time wasted on the non-technical work and can spend more time on the quality guarantee. The work efficiency is also elevated by this means.
