摘要
针对电子商务领域学术期刊体系不完善,研究成果分散等现状,提出一种结合文献计量学和概率主题模型LDA评价分析电子商务在其他学科领域产出成果的方法。以CNKI2006~2013年期间主要发表在7种图书情报类期刊中的电子商务相关研究为例,通过对比载文率、web下载量、总被引频次以及期刊他引率等指标,研究各期刊在电子商务领域的学术贡献力和影响力;其次,采用LDA主题建模,提取各期刊的研究主题,以把握图书情报领域电子商务相关研究的主题现状。实验结果揭示了近八年我国图书情报学对电子商务研究的发展状况。
E-commerce related studies published in seven library and information science journals during the period of 2006,--2013 in CNKI were evaluated and analyzed with traditional statistical analysis approach and the probabilistic topic model LDA. By comparing the published rate of papers, web downloads, total ci- tations and quotation rate by other journals, the academic contribution and influence of different journals in the researches about electronic commerce were studied. And from the implied research topics extracted by LDA, the semantic information and its distribution on the journals were discovered as well, which could help to grasp the e-commerce research status of library and information science domain. The results reveal the development situation of e-commerce related studies in library and information science from 2006 to 2013.
