摘要
[目的 /意义]提出3种主题演化模式:主题全局演化、主题团簇演化和主题协同演化,以期梳理学科知识结构的演化模式,进一步丰富揭示学科知识结构的研究范式。[方法 /过程]以Web of Science中2001-2015年间图书情报学领域的核心期刊文献数据为研究对象,以"计量学"为研究主题,基于时序分析、主题-关键词共现分析构建2-模网络,利用NetDraw对各主题演化模式进行可视化呈现。[结果 /结论]通过深入比较3种演化模式得出:主题全局演化可以直观、系统把握学科的历史轨迹和研究路径;以"团簇状"为子网络单元的主题团簇演化模式,可以更为细粒度、挖掘深度更高、更全面系统、真实具体地仿真主题演化;而主题协同演化,结合全局演化和团簇演化的优势,能以"联系与发展"的视角揭示主题在演化过程中彼此之间的关联程度及其融合与独立趋势。
[ Purpose/significance] The paper puts forward three theme tion＂ pattern, ＂Theme Agglomerate Evolution＂ pattern and ＂Theme Synergistic cipline knowledge structure evolution pattern, meanwhile to enrich the research evolution patterns：＂ Theme Global EvoluEvolution＂ pattern, so as to reveal the disparadigm that reveals the discipline knowledge structure. [ Method/process] According to data published in WoS core journals（2001 -2015 ） from the field of LIS as the research object, with ＂Metrology＂ as the research theme, based on timing analysis and ＂theme-keyword＂ co-occur- rence analysis, this paper constructs the 2 - model network, using NetDraw for visual expression. [ Result/eoneluslon ] Through comparing three evolution patterns in-depth, this paper draws a conclusion：the ＂Theme Global Evolution＂ pattern can directly and systematically grasp the discipline history and research path;＂ Theme Agglomerate Evolution＂ pattern can be more fine-grained, mining in depth, and more comprehensive and systematic to real and specific theme evolution;and ＂Theme Synergistic Evolution＂ pattern, can combine both of above theme evolution patterns advantages, from ＂contact and development＂ perspective to reveal the theme in the evolution process of the degree of association and the trend of integration and independence.
