| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Using decision tree analysis, we analyzed the growth of 1,200 active SNSs in So-net SNS (beta version). As a result, we could find a decision rule to distinguish rapidly growing SNSs in coming 3 months. Moreover, variable about network structures could improve the precision of the decision tree analysis. So, it was suggested from this result that network structure has affected growth of SNS. Furthermore, we classified rapidly growing SNSs into 4 groups based on their features. By analyzing transition of community structure about two typical SNSs, it was suggested that detailed analysis of network structure was promising. |
