Research on Academic Contributions of Major Countries of Library and Information Science Based on Time Series Perspective

[目的/意义]揭示2002年以来图情领域重要国家在学术论文产出的总量、引证、研究主题、学术合作等维度上的学术贡献与特征演化,为图情领域的学科建设及相关研究者追踪研究主题与前沿提供参考。[方法/过程]以近15年WoS数据库收录的图情领域86种核心期刊为研究对象,应用文献计量学、科学知识图谱、计量模型等研究方法,运用TDA、Ucinet、VOSviewer等数据分析工具,从学术论文的总量特征、引证特征、主题特征三个角度对图情领域重要国家的学术贡献进行深入分析,并构建计量模型考察空间距离及学术能力对重要国家之间学术合作的影响机制。[结果/结论]美国在图情领域的科研实力强劲,中国的学术贡献增速最快,荷兰、芬兰、比利时三国则在归一化被引比率指标上表现突出;研究主题主要集中在图书馆、信息检索、互联网、知识管理、社交网络、计量学、用户研究、研究方法8个主题范畴,英国、西班牙、中国、美国的研究主题最为广泛;空间距离与学术能力都对国家间的学术合作具有显著影响。

[ Purpose/significance ] The article reveals the academic contributions and evolution features of major countries of library and information science since 2002 on the dimensions of outputs of papers, citations and research topics, in the hope of providing a reference for the subject construction and related researchers tracking research topics and frontiers. [ Method/process] Based on 86 core journals in the last 15 years of library and information science in Web of Science, the article used research methods including bibliometrics, scientific knowledge maps and econometric models, utilized data analysis tools including TDA, Ueinet and VOSviewer. The article gave an in-depth analysis of the academic contribution of major countries of library and information science from the following perspectives： academic papers amount, citation features and theme features. Meanwhile, the article built a metrological model to examine the impact of spatial distance and academic ability on academic cooperation among major countries. E Result/conclusion J The United States has a strong scientific research strength in the field of library and information science, China has the fastest growth of academic contribution, Netherlands, Finland and Belgium all excel in quoted rate indicators. The research topics main- ly focus on the eight thematic areas of libraries, information retrieval, internet, knowledge management, social networks, metrology, user study and research methods. Britain, Spain, China and the United States have the most extensive research topics. Spatial distance and academic capabilities have a significant impact on academic cooperation among countries.
