概要	Social media network analysis applies social-network methods to the relationships among accounts on platforms — who follows, mentions, replies to, retweets, or shares whom — to reveal the structure of online conversation. By representing interactions as a graph and computing measures of centrality and community, it identifies influential actors, cohesive clusters, and the overall shape of public discourse around a topic.	Hyperlink network analysis (HNA) treats the hyperlinks among websites as social and communicative ties and applies social-network methods to the resulting web graph. Developed within webometrics by Park, Thelwall, and others, it reads a link from one organization's site to another's as a signal of endorsement, affiliation, or attention, and maps how actors — governments, NGOs, companies, media — are connected online.
