Hierarchical Semantic Community Detection in Information Networks: A Complete Information Graph Approach

2019 Tehnički Vjesnik  
In order to detect the hierarchical semantic community which is helpful to discover the true organization of information network,we propose a complete information graph approach.  ...  Experiment results show the hierarchical community detected by the simLV algorithm performs better than the Louvain in measuring the consistency of semantic content for our approach takes into account  ...  In fact, the study of hierarchical community reinforces the concept of community, for it performs a hierarchical analysis of the original detected communities.  ...
