科研团队竞争力可视对比分析方法

学术文献数据的爆炸增长使得找出重要的科研团队变得十分困难.如何评估团队的科研竞争力,比较不同的科研团队的科研成果,发现核心团队等问题变得越来越重要.为此,基于文献数据,构建了科研团队竞争力分级指标体系;通过引入派系强度改进了派系过滤算法,用于寻找合作网络中的科研团队;基于科研团队竞争力分级指标体系,设计了可视化对比分析方法,用于对比同一领域中不同的科研团队的科研竞争力.以天文领域真实的科研团队数据为例,实验结果和专家验证,证实了方法的实用性和有效性.

Visual Comparison Analysis of the Competitiveness of Scientific Research Groups

The explosive growth of academic publication data makes it very difficult to study research groups.How to evaluate and compare the competitiveness of research teams,and identify core groups is becoming more and more important.By leveraging the publication data,this paper proposes a hierarchical index system for depicting the competitiveness of research groups.We introduce an enhanced clique percolation method(CPM)by using the clique-strength to find research groups in co-author network.We design and implement a visual comparison approach to support interactive exploration of the competitiveness of different research groups in a field.Experiments and expert reviews on the case in the field of astronomy demonstrate the usefulness and effectiveness of our approach.
