摘要

本研究利用 RefCit2vec(一种受 word2vec 启发的嵌入方法)从文献库的角度概述了图书馆与信息科学的知识结构。四种独立的 RefCit2vec 模型将 1928 年至 2022 年间 35 种文献(期刊和论文集)中 62,077 篇文章的参考文献列表或被引文献列表转换为实数向量。RefCit2vec 的两个模型测得的文献相似度与书目耦合度量表现出适度的相关性。相比之下,其他两个模型测得的相似性与共引指标呈中度或强度相关。每个地点由其中心点表示,中心点是其组成文档的平均向量。通过对场馆中心点进行分层聚类,8 个聚类中有 6 个聚类稳健地出现了 69% 的场馆。四个聚类一致地形成了图书馆相关分支。文献计量学/科学计量学分支只包含 1 个聚类,而信息相关分支包含 3 个聚类。43% 的场馆属于 6 个树形结构一致的分组。如果一篇文章比一半的 SCIM 文章更接近 SCIM 中心点,则该文章被定义为 SCIM-alike。10%的JASIST文章在参考文献列表中与SCIM相似,5%的JASIST文章在被引文献列表中与SCIM相似。2008年至2018年期间,JASIST中SCIM-alike文章的比例高于平均水平,但自2019年以来,该比例降至平均水平以下。正如我们在 LIS 中展示的动态一样,像 RefCit2vec 这样的引文嵌入方法可以结合基于引文、基于文本或作者身份的特征,为调查或探索研究前沿和科学知识转移的各种场景做出贡献。

RefCit2vec: embedding models considering references and citations for measuring document similarity

This study outlines the intellectual structure of Library and Information Science in terms of the venues with RefCit2vec, an embedding method inspired by word2vec. The reference lists or cited-by lists of 62,077 articles in 35 venues (journals and proceedings) between 1928 and 2022 are converted into real number vectors by four independent models of RefCit2vec. The document similarities measured by the two models of RefCit2vec exhibit moderate correlations with bibliographical coupling metrics. In contrast, the similarities from the other two models moderately or strongly correlate with co-citation metrics. Each venue is represented by its centroid, the average vector of its constituent documents. By applying hierarchical agglomerative clustering on the venue centroids, 69% of venues robustly emerge in 6 out of 8 clusters. Four clusters consistently form the library-related branch. The bibliometrics/scientometrics branch contains only 1 cluster, whereas the information-related branch contains 3 clusters. 43% of venues are in six subgroups of consistent tree structures. An article is defined as SCIM-alike for it is closer to the SCIM centroid than half of SCIM articles are. 10% of JASIST articles are SCIM-alike upon their reference lists, and 5% of JASIST articles are SCIM-alike in terms of their cited-by lists. The percentage of SCIM-alike articles in JASIST hiked above the average between 2008 and 2018 but has dropped below the average since 2019. As we demonstrate the dynamics in LIS, citation embedding methods like RefCit2vec can incorporate citation-based, text-based, or authorship features to contribute to varied scenarios in investigating or exploring research fronts and scientific knowledge transfer.

期刊介绍: Scientometrics aims at publishing original studies, short communications, preliminary reports, review papers, letters to the editor and book reviews on scientometrics. The topics covered are results of research concerned with the quantitative features and characteristics of science. Emphasis is placed on investigations in which the development and mechanism of science are studied by means of (statistical) mathematical methods. The Journal also provides the reader with important up-to-date information about international meetings and events in scientometrics and related fields. Appropriate bibliographic compilations are published as a separate section. Due to its fully interdisciplinary character, Scientometrics is indispensable to research workers and research administrators throughout the world. It provides valuable assistance to librarians and documentalists in central scientific agencies, ministries, research institutes and laboratories. Scientometrics includes the Journal of Research Communication Studies. Consequently its aims and scope cover that of the latter, namely, to bring the results of research investigations together in one place, in such a form that they will be of use not only to the investigators themselves but also to the entrepreneurs and research workers who form the object of these studies.
