利用Web搜索引擎表征研究者和研究主题的跨学科性
Characterizing Interdisciplinarity of Researchers and Research Topics Using Web Search Engines
摘要：
研究人员的网络一直受到积极的建模和分析。早期的文献主要集中在引用或合作作者网络重建注释的科学出版物数据库，有几个局限性。近来，通用网络搜索引擎也被用于收集关于社交网络的信息。在这里，我们重建，使用网络搜索引擎，网络代表研究人员的相关性，他们的同行以及各种研究主题。研究者与研究主题的相关性表现为研究者关注某一特定主题，从而提高研究者的知名度。据观察，研究人员谁有高知名度提升了相同的研究主题往往是接近对方在他们的网络。我们计算了研究主题与研究人员在个人层面（与研究人员相关的主题多样性）和社会层面（他/她在研究人员网络中的中心地位）的跨学科性之间的相关性。我们发现，某些研究主题的知名度提升与研究人员的个人层面的跨学科性呈正相关，尽管它们与研究人员的普遍受欢迎程度呈负相关。研究还发现，网络相关主题的知名度提升与研究人员的社会层面跨学科性呈正相关。研究主题的相关性与研究人员的个人和社会层面的跨学科被发现是几乎相互独立的。这些发现表明，研究者的“跨学科性”的概念应该被理解为一个多维度的概念，应该使用多种评估手段进行评估。
英文摘要：
Researchers' networks have been subject to active modeling and analysis. Earlier literature mostly focused on citation or co-authorship networks reconstructed from annotated scientific publication databases, which have several limitations. Recently, general-purpose web search engines have also been utilized to collect information about social networks. Here we reconstructed, using web search engines, a network representing the relatedness of researchers to their peers as well as to various research topics. Relatedness between researchers and research topics was characterized by visibility boost-increase of a researcher's visibility by focusing on a particular topic. It was observed that researchers who had high visibility boosts by the same research topic tended to be close to each other in their network. We calculated correlations between visibility boosts by research topics and researchers' interdisciplinarity at individual level (diversity of topics related to the researcher) and at social level (his/her centrality in the researchers' network). We found that visibility boosts by certain research topics were positively correlated with researchers' individual-level interdisciplinarity despite their negative correlations with the general popularity of researchers. It was also found that visibility boosts by network-related topics had positive correlations with researchers' social-level interdisciplinarity. Research topics' correlations with researchers' individual- and social-level interdisciplinarities were found to be nearly independent from each other. These findings suggest that the notion of "interdisciplinarity" of a researcher should be understood as a multi-dimensional concept that should be evaluated using multiple assessment means.
