Community partition based chat system easy to join for new members

In a chat system, an increase of the participants leads to confusion of topics and makes it difficult to continue an orderly conversation. Moreover, senior participants tend to be familiar with each other and form a so-called community. This behavior of the senior users consequently makes newcomers hard to participate in the existing rooms. To cope with these problems, this paper proposes a community partition based chat system which divides overcrowded rooms to keep the proper number of participants. The system frequently estimates relationship between participants and separates the community members from the chat room. The separated members thus can continue to communicate with each other in another room newly generated, while the remained participants unacquainted with each other can make a beginning of the conversation. We had made an evaluation experiment on the proposed chat system and could obtain results which agree with the aim of our research
