ISI Web Of Knowledge Platform And Its Comparative Research

On account of www hyperlink feature, the Institute for Scientific Information (ISI) of America establishes an academic information resources integration platform (ISI web of Knowledge-WOK) based on knowledge, it is a digital research environment that constructed by design ideas of "one-stop" information service. The platform utilizes internal relation between information resources to provide a variety of related resources to researchers, it also possesses many functions of knowledge retrieval, extraction, management, analysis and evaluation.The thesis aims at conducting thorough investigation and research of the architecture and function module of the WOK platform, mainly includes five sections, the first section is preface, it generalizes the background and meaning of selecting the thesis topic, then it analyzes the present situation of research at home and abroad from two aspects of data statistics and research content, and it points out research methods and innovation points of the thesis; the second section is WOK platform system, on the one hand, it simply introduces the platform from such contents as development process and resource composition, on the other hand, it categories the database of the platform by database structure, other resources and analysis tools; the third section is WOK platform function, it introduces retrieval function, analysis function and personalized service of the platform from multiple angles, this section and the second section are the main content of the thesis, introduces the platform in all directions; the fourth section is the comparison between WOK and CNKI, this is the key content of the thesis, firstly, it compares collection situation of two platforms from resource composition and subject range, secondly, it carries out an further subdivided comparison of the platform function from aspects of retrieval function, result process, analysis function and personalized service, finally, it sums up the whole comparison results, and gives the inspiration; the fifth section is epilogue, it summarizes the research content of the entire thesis, and looks into the future of the database retrieval system on this basis.The section of comparison research of the thesis provides certain reference value, it mainly compares WOK with CNKI, summaries many-sided revelations by analyzing comparison results, helps CNKI and other domestic databases perfect the functions of themselves, improves the service level of the whole academic system.
