Analysis on characteristics of structural hole for weighted co-author networks
Zhao Sh · Computer Engineering and Applications Journal · 2016
The scientific research cooperation is becoming more and more popular. There are a large number of complex networks, such as citation networks, co-citation networks and co-author networks and so on. Mining the structural hole in a co-author network is helpful to improve a team's innovation ability of the scientific research cooperation. Most of the analysis on the structural hole is the unweighted network. In order to study the closeness on the characteristics of structural hole, it focuses on the weighted co-author networks. By introducing the weight into the constraint function of structural hole, and then improving the existing algorithm HIS for structural hole, it proposes a weighted algorithm for structural hole(W_CIHIS algorithm). With constraint as measurement for mining structural hole spanners and the public datasets, it compares the W_CIHIS algorithm and the original one. The experimental results show that W_CIHIS algorithm works better.
