An Investigation on the network structure and trend grasp of information science related research

信息技术在社会中扮演着越来越重要的角色，并将被应用到新的领域。信息技术得到了各种信息相关研究的支持。这些研究不仅在信息科学领域，而且在各个研究领域都在进行。例如，生命科学领域正在专门产生生物信息学的新领域。预计其他领域也会因为与信息学的融合而发展成为一个新的复合研究领域。这样一个新领域的形成，可以认为是在科研论文的被引条件或基础研究基金资助的课题中出现了一个迹象。本文运用多元视角的统计技术和文献计量学技术，阐述了本研究的目的。目标是(1)尽快定量地发现上述预兆，并提取主题以优势推广。从现在开始，(2)通过展示现有研究领域之间网络结构的时间变化，为研究主题的创建提供有利于研究主题的信息。在本研究中，我们从2001财年开始，利用关键词分析法不断发展域间关系的分析方法。本文以2003年教育部对学科分类进行重大调整的科研资助项目数据为例，分析了学科分类调整前后情况的关系。此外，信息学领域的研究者从问卷调查的结果中贡献了什么样的杂志，或者当时是否知道哪本杂志是“权威杂志”，进行文献计量学分析。经过三年的研究，基本建立了分析技术，得到了如下所示的三个结果。(1)科研资助研究领域代码中“信息研究”领域与“一般、复杂新领域”的领域间关系图。(2)学术杂志的相互关联程度，或期刊与国家信息学研究所开发的CJP数据库资助研究领域的关联程度。(3)利用关键词分析技术，结合助学金数据库，显示了“基因组相关”和“纳米技术相关”研究领域的研究课题数量或资助总额及其时间变化。本文提出的关键词分析技术具有广泛的应用前景。用这笔预算购买的专利数据库的分析正在进行中。因此，我们期望将该技术以及其他文献计量学技术应用于各种数据库，可以得到各个方向的结果。少

Information technology has been coming to act as the important role in the society, and it will be applied to the newer field. The information technology has been supported by various information related studies. Those researches are being done in not only the information science field but also the various research fields. For example, the new area of bioinformatics is specially being produced in the life science field. It expects that even other fields will develop into a new compound research field due to the fusion with an informatics study.The formation of such a new area can be thought that a sign is appearing in the citation conditions of research papers or in the funded subjects of the basic research-funds. The aims of this research are described as below by using a statistical technique from the diversified point of view and bibliometric technique. The goals are (1) discover the above omen as soon as possible quantitatively, and extract the subject to promote it preponderantly … More from now on, (2) provide an information which conducible for the creation of the research theme by showing a time variation in the network structure between the existing research fields.In this study, we have been continuously developing the analysis method for inter-field relationship using keyword analysis from FY2001. Using the data of the Grant-in-Aid for Scientific Research in 2003 for which the ministry undertook a large revision to the classification of academic fields, we show the relationship between the situations before and after the classification changes. Moreover, the researcher of the information science field contributed to what kind of magazine from a result of questionnaire investigation, or the matter whether then it was aware of which magazine as "authoritative magazine" was analyzed for bibliometric analysis.The analysis technique was almost established by granted three years studies, and the three of results as shown below were obtained. (1) The map of inter-field relationship between "information studies" area and "General and Complex New Areas" in the research field codes of Grant-in-Aid for Scientific Research. (2) Degree of associations of academic magazines each other, or between the magazines and research fields of Grant-in-Aid using CJP database developed by National institute of informatics. (3) The number of adopted research subjects or total grants and their time variations are shown using keyword analysis technique in the research fields of "Genome-related" and "Nanotechnology-related" with database of Grant-in-Aid.The technique of keyword analysis developed here is widely applicable. And an analysis with the patent database that purchased by this budget is proceeding. So we expect that a result in each direction come out using this technique as well other bibliometric technique with applying to various database. Less
