Who Is the Most Important Character in Frozen? What Networks Can Tell Us About the World

Abstract

How do we determine the important characters in a movie like Frozen? We can watch it, of course, but there are also other ways-using mathematics and computers-to see who is important in the social network of a story. The idea is to compute numbers called centralities, which are ways of measuring who is important in social networks. In this paper, we talk about how diierent types of centralities measure importance in diierent ways. We also discuss how people use centralities to study many kinds of networks, not just social ones. Scientists are now developing centrality measures that also consider changes over time and diierent types of relationships. kids.frontiersin.org July yyyy | Volume ee | Article ee |
