| Abstract(in English) | In this paper, to improve in query processing on a peer-t(>peer (P2P) system, we introduce a new distributed index, named Direct Index (DI), where a peer stores other peer information such as a usefulness of a peer in own DI. When a peer starts a query using a DI, because effective query message routing besed on the usefulness of peers can be achieved, a DI enables to improve in scalability. To enable the discovery of a useful document, we also introduce replication methods besed on dynamic peer grouping, which are expected of an improvement in query success rate. To ensure effects by proposal methods, we show experimental results on query processing. |
