CentralityDifferent Influence Models of Node Centrality in Transactional Community

چکیده
This study investigates the various influence models of nodes' network centrality in the context of transactional community. Combining the Social Network Analysis (SNA) with Tobit regression, the research indicates that: i) a node's degree centrality (its followers) and betweenness centrality (the number of the shortest paths in which the node is included) have a positive impact on its network influence, ii) the closeness centrality (physical closeness in network) shows no significant impact on its influence. Theoretically, the results provide insight into the sources of influence and various influence models of different node centralities in transactional community network. In practice, influentials can be better identified according to different centralities, so as to distinguish the opinion leaders in a more accurate way.

متن کاملCommunity Detection using a New Node Scoring and Synchronous Label Updating of Boundary Nodes in Social Networks
Community structure is vital to discover the important structures and potential property of complex networks. In recent years, the increasing quality of local community detection approaches has become a hot spot in the study of complex network due to the advantages of linear time complexity and applicable for large-scale networks. However, there are many shortcomings in these methods such as in...
متن کاملInformation extraction with network centralities: finding rumor sources, measuring influence, and learning community structure
Network centrality is a function that takes a network graph as input and assigns a score to each node. In this thesis, we investigate the potential of network centralities for addressing inference questions arising in the context of large-scale networked data. These questions are particularly challenging because they require algorithms which are extremely fast and simple so as to be scalable, w...

The existing trade models suggest that for tradable goods potential partners can be many, but eventually only one (the one offering the best price) should be selected, therefore relatively few (unidirectional) trade links will appear between countries. If the structure of international trade flows describes as a network, trade link would give rise between countries. This paper exploit recently-...
متن کاملInterplay between Social Influence and Network Centrality: A Comparative Study on Shapley Centrality and Single-Node-Influence Centrality
We study network centrality based on dynamic influence propagation models in social networks. To illustrate our integrated mathematical-algorithmic approach for understanding the fundamental interplay between dynamic influence processes and static network structures, we focus on two basic centrality measures: (a) Single Node Influence (SNI) centrality, which measures each node’s significance by...
