    摘要： A dense data-set mining system and method is provided that directly exploits all user-specified constraints including minimum support, minimum confidence, and a new constraint, known as minimum gap, which prunes any rule having conditions that do not contribute to its predictive accuracy. The method maintains efficiency even at low supports on data that is dense in the sense that many items appear with high frequency (e.g. relational data).

    摘要： A mechanism for information retrieval in fully decentralized, distributed, peer-to-peer network systems. Peer profiles are aggregated and collected in real-time by each peer. Each peer uses and integrates knowledge that it collects during query-reply cycles for each future query received, thereby learning over time and making information retrieval a more intelligent and rapid process. Each peer then autonomously decides which of its peers are most likely to have an answer to a given query. A routine is provided for monitoring the messages and profiling each peer, building a local peer profile for each node exchanging messages in the peer-to-peer network based on messages passing through the node.
