摘要
ResearchGate为代表的学术社交网络逐渐引起图情学科用户的重视,针对其高影响力科研成果主题内容的揭示,将丰富用户对不同媒介下学科的发展动向与研究重点的认知,亦有助于合理利用学术社交网络来提升个人影响力。文章选取学术社交网络中图情学科高影响力科研成果为研究对象,构建LDA模型挖掘摘要内容,引入来源年份信息分析各时期主题演化情况,在跨媒介比较中揭示网络交流背景下其呈现的内容特征。研究提炼健康信息学、用户信息行为、算法技术、应用开发、通信网络5个主题。从主题强度变化来看,健康信息学表现平稳,用户信息行为、通信网络呈现上升趋势,算法技术、应用开发整体出现下降。与期刊等传统媒介得到的结论相比,学术社交网络中的研究主题与其虽具有一定相似性,但更凸显出学科交叉融合特征。
The revelation of the main characteristics and subject contents of research publications could help scholars grasp the development trend and research focus of the discipline,and then make full use of academic social networks to enhance personal influence.As a typical Internet academic platform,ResearchGate has gradually attracted the wide attention of LIS scholars.Thus,taking ResearchGate as an example,this paper first sorts out LIS research publications with high web impact,and then constructs a LDA model to further mine their abstracts.At the same time,it analyzes the thematic evolution of different periods,and makes a qualitative comparison of source journal fields,revealing the content characteristics of those high web impact research publications under the background of network communication.Through a text mining of the abstracts,five themes are summarized,i.e.,health informatics,information behavior,algorithm technology,application development,communication network,some of which correspond to the academic background of the source journals and high-yield core authors.The research publications in computer science,library and information science are more likely to be closely concerned by users,while the related interdisciplinary research topics are relatively low.In terms of subject intensity evolution,health informatics shows stable performance,information behavior and communication network show rising trend,and algorithm technology and application development show an overall decline.Though similar to the conclusions of traditional media such as journals,the former five summarized themes highlight interdisciplinary integration.
