    Subjects: Library Science,Information Science >> Library Science submitted time 2023-08-27 Cooperative journals: 《图书情报工作》

    Abstract: [Purpose/significance] In order to explore whether the measurement results of Altmetrics indicators are consistent in the evaluation of subject papers, this paper attempts to build a comprehensive literature evaluation model based on Altmetrics through the existing measurement data, and to create new metrics for the evaluation and reuse of data.[Method/process] In this study, the Altmetrics indicators of all articles published in the Civil Engineering disciplines from 2009 to 2016 on the PLoS ALMs are obtained. The 15 original indicators are divided into 4 principal components using correlation analysis and principal component analysis methods, which are applied to specific disciplines. It analyzes the correlation between the single index and the comprehensive evaluation index of Altmetrics, and uses the fairness test method to explore the differences in the relevance of time to the evaluation of the paper.[Result/conclusion] The study finds that after using the fairness test method to eliminate time impact, the relevance of the citation indicators has increased, while the indicators related to social media communication have declined. But the Twitter index has not decreased, and it has always been highly correlated with the F value.

  • 开放知识环境下智库信息资源配置理论研究

    Subjects: Library Science,Information Science >> Information Science submitted time 2018-08-14 Cooperative journals: 《智库理论与实践》

    Abstract: [目的/意义]在当前的开放知识环境中,信息资源的有效配置能够对智库知识的有效生产与供给带来积极影响。因此需要将信息资源配置这一解释/分析工具引入到智库研究中来,用以解决当前我国新型智库建设过程中出现的现实问题。[方法/过程]分析了智库信息资源配置的理论构成单元和理论基础,构建了智库信息资源配置的理论框架,明确了框架下需要解决的关键问题。[结果/结论]开放知识环境提供了信息资源配置的对象,智库提供了信息资源配置的方向,智库信息资源配置的实质是信息资源与信息需求之间的匹配。在未来研究中需要对智库的信息内容、信息需求、信息行为进行深入调查,并建立智库信息资源配置效率和智库影响力之间的关联。

  • 主流Meta分析软件功能及其在领域知识发现的拓展应用研究

    Subjects: Library Science,Information Science >> Information Science submitted time 2017-10-11 Cooperative journals: 《数据分析与知识发现》

    Abstract:【目的】研判Meta 分析的未来发展趋势, 为基于Meta 分析的领域知识发现提供借鉴。【方法】梳理对比国际常用的Meta 分析软件的特点及其计算、绘图等功能的差异, 并以资源环境学科领域为例, 提出适合具体领域知识发现的Meta 分析工具应具有的基本特点。【结果】通过对具体领域分析, 开发一套操作界面规范、运算步骤简单、分析结果准确、面向对象大众的文献综合集成工具的基本构想。【局限】并未通过构建平台系统地实施, 充分验证设想的可行性; Meta 分析固有的一些弱点如“苹果”、“橘子”问题, 无法在基于Meta 分析的领域知识发现中有效解决。【结论】需基于Meta 分析构建领域知识发现的平台, 以指导领域文献知识发现的拓展应用。
