○ 제목 : Signed Network Analysis and Its Applications -- Network Embedding and Node Ranking
○ 초록 : Recently, there has been a surge of interest on signed networks with both positive and negative edges between nodes. For example, sites such as Slashdot (a technology news site) or Epinions (a now-defunct consumer review site) allow users to decide whether users trust (i.e., positive edges) or distrust (i.e., negative edges) each other. In such a setting, the edge signs provide rich semantics between nodes. However, many network analysis techniques were designed for (unsigned) networks with only positive edges between nodes. This talk will cover topics related to signed network mining. In this talk, I will briefly share two social theories in signed networks and then introduce our recent works for network embedding (SIGIR'20) and personalized node ranking (SIGIR'21).
