【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。
【Objective】 To investigate the future development trend of Meta analysis and provide references for the field knowledge discovery based on Meta analysis. 【Method】 Combing the features of common international Meta analysis software and the differences in their functions such as calculation and drawing, the paper presents the basic characteristics of meta-analysis tools suitable for domain-specific knowledge discovery, taking the field of resource and environment as an example. 【Result】 Through the analysis of specific fields, we developed a set of basic concepts of document integration tools with simple operation interface specification, simple operation steps, accurate analysis results and object-oriented public. [Limitations] are not implemented systematically through the construction platform to fully verify the feasibility of the idea. Some weaknesses in Meta analysis such as “Apple ” and “Orange ” can not be validated in domain knowledge discovery based on meta-analysis solve. 【Conclusion】 It is necessary to build a platform for domain knowledge discovery based on Meta analysis to guide the expansion and application of document knowledge discovery in the field.
