[目的/意义] 在科学研究中,科研团队通过学术交流互动推动着科学进步。以计算语言学领域为例,识别科学领域中科研团队的角色并探究其特征。[方法/过程] 通过构建机构作者合作网络,运用社群识别算法发现科研团队,结合论文引用关系构建科研团队引证网络,基于蝴蝶结模型和网络位置理论划分出领导者、中介者、追随者和孤立者等4种角色的科研团队。[结果/结论] 不同角色的科研团队在成员数量、发文量、合作强度等3个方面具有不同的特征。如领导者角色的团队数量最少而平均规模较大,追随者角色团队数量最多而团队规模较小,中介者团队合作密度与团队的发文量之间存在着显著的负相关关系,孤立者角色的团队与其他团队几乎不存在引证和被引关系。 相似文献

学术颠覆性创新作为科学创新的重要组成部分,已经成为当代科技进步和经济发展的新引擎。然而,我们对学术颠覆性创新产生的关键影响因素依然知之甚少。因此,本文以学术创新的主体即科研团队为研究对象,从信息多样性、社会属性多样性和行为意愿多样性三个层面,系统分析了科研团队的组成多样性对学术颠覆性创新的影响机制。首先,本文基于微软学术图谱中1950—2019年人工智能领域的合作文献为数据源,使用主题模型、文本挖掘等技术对作者特征进行抽取和表示,构建科研团队多样性指标体系;同时,通过计算每篇文献的颠覆性创新指数,以衡量其学术颠覆性创新程度。然后,采用相关性分析和OLS (ordinary least squares)回归分析,剔除与学术颠覆性创新显著不相关的科研团队多样性指标,得到候选指标集。最后,利用广义精确匹配方法,构建因果模型以揭示科研团队多样性与学术颠覆性创新之间的因果关系。研究结果表明,在人工智能领域,科研团队的主题多样性和国家多样性均与学术颠覆性创新程度呈现负向因果效应：科研团队主题多样性的增加,会使学术颠覆性创新程度下降8.776%～19.000%;科研团队国家多样性的增加,会使学术颠覆... 相似文献

This paper explores a possible approach to a research evaluation, by calculating the renown of authors of scientific papers. The evaluation is based on the citation analysis and its results should be close to a human viewpoint. The PageRank algorithm and its modifications were used for the evaluation of various types of citation networks. Our main research question was whether better evaluation results were based directly on an author network or on a publication network. Other issues concerned, for example, the determination of weights in the author network and the distribution of publication scores among their authors. The citation networks were extracted from the computer science domain in the ISI Web of Science database. The influence of self-citations was also explored. To find the best network for a research evaluation, the outputs of PageRank were compared with lists of prestigious awards in computer science such as the Turing and Codd award, ISI Highly Cited and ACM Fellows. Our experiments proved that the best ranking of authors was obtained by using a publication citation network from which self-citations were eliminated, and by distributing the same proportional parts of the publications’ values to their authors. The ranking can be used as a criterion for the financial support of research teams, for identifying leaders of such teams, etc. 相似文献

目的：构建2004－2013年糖尿病领域高被引论文主体的合作网络知识图谱,揭示主要作者、机构和国家,分析其合作模式。方法：用可视化软件Citespace绘制2004－2013年糖尿病领域高被引论文的作者、机构、国家合作网络图谱。结果：核心作者是Graham Nichol、SM Grundy和Hertzel C．Gerstein等,团体内部合作密切,团体间合作极少。核心研究机构是Harvard Univ、Brigham＆Womens Hosp、Univ Sydney等,大学成为科研的主要力量。最有影响力的发文国家是美国、英国和加拿大,合作十分密切。结论：2004－2013年糖尿病领域高被引论文主体合作模式有单点型、双核型、发展型和完备型4种。基于地缘和机构属性的合作还处于摸索与探索阶段,应进一步加强地域间,高校、医疗机构、事业单位和科研机构间的合作与交流。 相似文献

ABSTRACTToday’s most pressing scientific problems necessitate scientific teamwork; the increasing complexity and specialization of knowledge render “lone geniuses” ill-equipped to make high-impact scientific breakthroughs. Social network research has begun to explore the factors that promote the assembly of scientific teams. However, this work has been limited by network approaches centered conceptually and analytically on “nodes as people,” or “nodes as teams.” In this article, we develop a “team-interlock ecosystem” conceptualization of collaborative environments within which new scientific teams, or other creative team-based enterprises, assemble. Team interlock ecosystems comprise teams linked to one another through overlapping memberships and/or overlapping knowledge domains. They depict teams, people, and knowledge sets as nodes, and thus, present both conceptual advantages as well as methodological challenges. Conceptually, team interlock ecosystems invite novel questions about how the structural characteristics of embedding ecosystems serve as the primordial soup from which new teams assemble. Methodologically, however, studying ecosystems requires the use of more advanced analytics that correspond to the inherently multilevel phenomenon of scientists nested within multiple teams. To address these methodological challenges, we advance the use of hypergraph methodologies combined with bibliometric data and simulation-based approaches to test hypotheses related to the ecosystem drivers of team assembly. 相似文献

[目的/意义] 为便于机构人才引进,构建领域核心团队识别规范化流程,从核心区域作者确定、团队指导/师承关系判别、团队发刊倾向和团队研究方向4个方面对领域核心团队进行挖掘研究。[方法/过程] 首先,进行数据前期规范;然后,结合作者合著无向二值矩阵与核心-边缘结构分析,划分核心区域作者,综合多维指标对核心区域作者进行适当调整;最后,基于第一作者与其他作者的有向合著网络,识别领域核心研究团队。[结果/结论] 在厘清团队指导/师承关系判别基本流程上,提炼通用性规律,包括：①在"外射星型"拓扑结构的合著团队中,处于中心位置节点有较高概率为导师/指导者,而"内聚星型"拓扑结构合著团队位于网络中心的作者科研能力较强;②在第一作者与其他作者的有向合著网络中,两个节点若同时具备第一作者与通讯作者关系、有相同的所属机构、学术年龄有一定差距,则这两个节点间一定存在指导关系,有较高的概率存在师承关系。 相似文献

The growing complexity of scientific challenges demands increasingly intense research collaboration, both domestic and international. The resulting trend affects not only the modes of producing new knowledge, but also the way it is disseminated within scientific communities. This paper analyses the relationship between the “degree of internationalization” of a country’s scientific production and that of the relevant citing publications. The empirical analysis is based on 2010-2012 Italian publications. Findings show: i) the probability of being cited increases with the degree of internationalization of the research team; ii) totally domestic research teams tend to cite to a greater extent totally domestic publications; iii) vice versa, publications resulting from international collaborations tend to be more cited by totally foreign publications rather than by publications including domestic authors. These results emerge both at overall and at discipline level. Findings might inform research policies geared towards internationalization. 相似文献

Incorporating fresh members into teams is considered a pathway to team creativity. However, whether freshness improves team performance or not remains unclear, as well as the optimal involvement of fresh members for team performance. Focusing on team impact, one important dimension of team performance, this study uses a group of authors on the byline of a publication as a proxy for a scientific team and quantifies team impact by citations of a paper authored by this team, i.e., article team impact. We extend an indicator, i.e., article team freshness, to measure the extent to which a scientific team incorporates new members, by calculating the fraction of new collaboration relations established within the team. Based on more than 43 million scientific publications covering more than a half-century of research from Microsoft Academic Graph, this study provides a holistic picture of the current development of article team freshness by outlining the temporal evolution of freshness, and its disciplinary distribution. Subsequently, using a multivariable regression approach, we examine the association between article team freshness and papers’ short-term and long-term citations. The major findings are as follows: (1) article team freshness in scientific teams has been increasing in the past half-century; (2) there exists an inverted-U-shaped association between article team freshness and papers’ citations in all the disciplines and different periods; (3) article team impact is hampered by article team freshness in small-sized teams, while medium-sized and large-sized teams can benefit more from article team freshness before the fraction of new collaboration reaches its turning point. The findings of this study provide implications for the practice of team formation and team management in science. 相似文献
