In this paper, we present and compare various centrality measures for graphbased keyphrase extraction. Through experiments carried out on three standard datasets of different languages and domains, we show that simple degree centrality achieve results comparable to the widely used TextRank algorithm, and that closeness centrality obtains the best results on short documents.

In the US House and Senate, each piece of legislation is sponsored by a unique legislator. In addition, legislators can publicly express support for a piece of legislation by cosponsoring it. The network of sponsors and cosponsors provides information about the underlying social networks among legislators. I use a number of statistics to describe the cosponsorship network in order to show that ...

We investigate the correlation between the information theoretic measure of empowerment and the graph theoretic measure of closeness centrality, to better understand the structural conditions that must exist in a world for learning and adaptation. We examine both measures in both a simple gridworld scenario, represented as a graph, and on a scale-free graph. We show a strong correlation between...

Have you ever wondered what God’s inner emotional life might be like? Within Christian thought, there are conflicting answers to this question. The majority of theologians throughout history have said that God cannot moved by creatures feel anything. does not literally empathy, mercy, or compassion. Instead, only feels pure undisturbed happiness. This view is called divine impassibility. In the...

Cultural differences in individualism and collectivism (I-C) describe important variations in how the self relates to others, but existing scales may be too broadband to precisely measure this aspect of I-C. They also do not distinguish among particular ingroups and types of interdependence with them. The Circles of Closeness scale addresses these limitations. Initial results from Euro-American...
