    Ren Ruijuan, Mi Jia, Pu Demin, Zhang Shouhua, Liu Libin, Wang Le
    2011, 27 (3): 9-16.  DOI: 10.11925/infotech.1003-3513.2011.03.02
    Abstract   HTML   PDF (624KB) ( 600 )
    After examining some Ontology projects at home and abroad, considering the distribution of Ontology, the authors use a hybrid pattern to construct Ontology with distributed database. On the basis of the readjusted inter-concept relationship, which is one of advance works, ADORES (A Distributed Ontology Retrieval and Editing System) is developed in ASP.NET platform to build the distributed Ontology library. In this paper, the designing ideas and functions of ADORES is introduced firstly, then the key points in ADORES development and their solution methods are emphasized.Finally, some key codes of the difficult points, such as the export of OWL and SKOS standard description format, realization of concept tree and processing of relation reversibility are demonstrated.

    Services Platform for Knowledge Retrieval Based on CSSCI_Onto
    Wang Hao, Su Xinning
    2011, 27 (3): 22-29.  DOI: 10.11925/infotech.1003-3513.2011.03.04
    Abstract   HTML   PDF (1009KB) ( 441 )
    The CSSCI information services system can only provide single and linear retrieval, and the retrieval effect is not very good. The main reason lies in the unreasonable data organization background. Therefore, the authors put forward the solution which uses knowledge services platform based on Ontology instead of the existing CSSCI information services system, and provide the services in the level of knowledge, so that to improve the retrieval environment. The paper proposes a general model of information retrieval system based on Ontology, designs a practical knowledge services platform named KRSP_CSSCI_Onto, and gives the basic functions and system framework of the platform. An experimental knowledge retrieval system is developed hereby, and the applications of Ontology in knowledge retrieval services is expounded in detail, including semantic extension of search expression, related knowledge recommendation of query results, knowledge navigation based academic resource networks model and knowledge relationships retrieval based rule library.

    Association Analysis of Academic Periodicals Based on CSSCI_Onto
    Deng Sanhong, Wang Hao, Su Xinning
    2011, 27 (3): 30-37.  DOI: 10.11925/infotech.1003-3513.2011.03.05
    Abstract   HTML   PDF (1539KB) ( 433 )
    The paper tries to change the traditional analysis mode of academic resources evaluation, and puts forward the “knowledge-driven” analysis idea which establishes a complete knowledge base firstly, then obtains conclusions on the basis of this knowledge base. For this, the paper adopts the Ontology mechanism to achieve the knowledge organization for CSSCI academic resources, which describes the periodicals and related knowledge by object-oriented approach, so that to establish CSSCI Academic Resource Networks Model (CSSCI_Onto). On this basis of academic knowledge annotated in the Ontology, not only the relationship and association degree between periodicals can be learned comprehensively, but also the bidirectional and multiple association patterns that are implied in original knowledge can be mined, and further the set of core periodicals in the disciplinary during certain period of time can be discovered, which provides factual basis for cooperation and division between periodicals, so that to promote a reasonable distribution of research content of periodicals. The paper focuses on the construction and analysis for relationship of periodicals, which is a part of academic resources association analysis based on CSSCI_Onto.

    Scholars Knowledge Map Construction and Analysis Based on CSSCI
    Hu Yuanjiao, Wang Hao
    2011, 27 (3): 38-44.  DOI: 10.11925/infotech.1003-3513.2011.03.06
    Abstract   HTML   PDF (732KB) ( 425 )
    In order to promote the academic cooperation and development, provide factual basis for the inter-scholar cooperation and obtain analysis conclusion for supporting decision, this paper tries to introduce the Ontology mechanism into the knowledge organization of CSSCI academic resource for organizing concepts related to scholars knowledge map by object-oriented approach, so that to establish scholars knowledge map concept model based on CSSCI. Then the association analysis and knowledge mining are used to discover the potential cooperating probability between scholars and find the related authors who can influence the core authors academically in some discipline field. At the same time the authors group is classified definitely based on the relationship, which can strengthen related field’s research and cooperation, and realize knowledge complement as well as achievement reference and inspiration.

    Anchor and Link Text Expansion Based KBES Algorithm Tunneling Strategy
    Qiao Jianzhong
    2011, 27 (3): 45-50.  DOI: 10.11925/infotech.1003-3513.2011.03.07
    Abstract   HTML   PDF (483KB) ( 397 )
    On the basis of summary of “true or false tunnel” strategy on focused crawler, this paper proposes a new KBES algorithm to solute the “false tunnel” problem. The experiments prove that KBES algorithm can improve the efficiency to predict the relevance of new links by anchor and link text in the heuristic strategies to some extent.

    Application of Genetic Algorithm to Identify Hot Topics from Medical Literature
    Zhang Han, Han Shuang, Bai Xing, Cui Lei
    2011, 27 (3): 57-61.  DOI: 10.11925/infotech.1003-3513.2011.03.09
    Abstract   HTML   PDF (519KB) ( 432 )
    This paper firstly creates Medical Subject Headings (MeSH) feature vector for medical literature, then searches for the latest cited times of each paper after published two years, which serves as the indicator for hot papers. Using a genetic program, a group of MeSH terms representing the content of hot papers are extracted. The method is tested on the topic of neoplastic stem cells,and the results from term frequency analysis are served as a baseline. The outputs of two methods are evaluated by domain experts,and the results show that genetic algorithm based method has a better performance than term frequency based method.
