Sammanfattning	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.	Network agenda-setting (NAS), also called third-level agenda setting, extends classic agenda-setting theory by proposing that news media transfer to the public not only the salience of issues (first level) and of attributes (second level), but the very web of associations among issues and attributes. Introduced by Lei Guo and Maxwell McCombs, the method represents the media agenda and the public agenda as networks and tests whether the media's bundling of elements is reproduced in the public's mind.
