基于关键词分布相关性和社区发现的合著者网络专家定位

Expertise localization discovered through correlation of key term distribution and community detection in co-author networks

摘要:

我们提出了一个高效和有效的自动方法来确定合作作者网络中发现的科学社区的研究重点。它利用数据库中的书目数据来形成网络,然后通过快速贪婪社区发现来识别网络中大型连接组件中的社区。文本分析技术被用来识别代表社区主题的社区特定的重要术语。为了大大减少计算时间,对网络中每份出版物的“主题”字段而不是其整个文本进行分析。使用这种文本分析方法需要一定程度的统计置信度,因此使用这种技术分析非常小的社区并不有效。我们发现一个最小的社区规模阈值8合著论文;低于这个值,社区的主题不能可靠地识别与此方法。此外,我们认为这项研究的影响,在合著网络的科学社区的形成所涉及的因素。

英文摘要:

We present an efficient and effective automatic method for determining the research focus of scientific communities found in co-authorship networks. It utilizes bibliographic data from a database to form the network, followed by fastgreedy community detection to identify communities within large connected components of the network. Text analysis techniques are used to identify community-specific significant terms which represent the topic of the community. In order to greatly reduce computation time, the `Topics' field of each publication in the network is analyzed rather than its entire text. Using this text analysis approach requires a certain level of statistical confidence,therefore analyzing very small communities is not effective with this technique. We find a minimum community size threshold of 8 coauthored papers; below this value, the community's topic cannot be reliably identified with this method. Additionally, we consider the implications this study has regarding factors involved in the formation of scientific communities in co-authorship networks.
