| Abstract(in English) | Some studies have shown that using by a single scale-free network is not appropriate for modeling social networks that represent human relationships in real world. In the social networks, multiple community networks based on common interests or values exist together. However, there is no study on communication model where multiple community networks are taken into consideration. Moreover, the evaluation that considers the load-balancing of the hub node in the scale-free network is done as an application of the information search by crossing of multiple networks. In this paper, we investigate how the performance of information retrieval is affected by using multiple community networks. To evaluate the performance, we use a degree of density which denotes the processing cost of hub nodes as well as the distance.We show that the performance of information retrieval by crossing different community networks improves in terms of the number of hops and degree of density on any path between two nodes. |
