Method of extracting community and system for the same
First Claim
1. A community extracting method to be executed by an information processing apparatus including at least data storing means for storing data and data processing means for processing the data stored in said data storing means, the community extracting method comprising steps of:
- forming a human relationship network indicating relationships of users and storing said human relationship network in said data storing means;
forming a dendrogram formed by clustering relationship data of said users in accordance with a similarity degree and storing said dendrogram in said data storing means;
extracting one or more communication cores each including at least a portion of said users as constituent members, from said human relationship network;
mapping said communication core to said dendrogram to extract a community including at least the portion of said constituent members.

Abstract
A community is extracted by executing steps of: clustering relationship data; extracting a communication core of a relationship network; mapping the communication core to a dendrogram of relationship data; forming a community by using the dendrogram in accordance with a similarity degree of relationship data while the cluster is expanded; and aggregating communities. A community of a set of persons having high density relationships based on common topics and interests can be extracted from a set of human relationships and relationship data representative of the human relationships.
