Social Behaviours Applied to P2P Systems: An efficient Algorithm for Resource Organisation [article]

V. Carchiolo, M. Malgeri, G. Mangioni, V. Nicosia
2007 arXiv   pre-print
Such a network smoothly evolves to a small--world graph, where queries for resources are efficiently and effectively routed.  ...  Peers in PROSA self--organise in social groups of similar peers, called "semantic--groups", depending on the resources they are sharing.  ...  In a flooding network queries are routed using a classical flooding algorithm; in a random walk network query are forwarded through randomly chosen links.  ...

p2pDating: Real life inspired semantic overlay networks for Web search

Josiane Xavier Parreira, Sebastian Michel, Gerhard Weikum
2007 Information Processing & Management  
In the spirit of the natural notion of autonomous peers participating in a P2P system, our strategy creates semantic overlay networks based on the notion of "peer-to-peer dating": Peers are free to decide  ...  A challenging task in such systems is to efficiently route user queries to peers that can deliver high quality results and be able to rank these returned results, thus satisfying the users' information  ...  Finding New Friends Friend lists, besides defining the links in the SONs, can also be used to find new friends in a very intuitive manner, by routing over semantic routing tables of different peers: if  ...

Ontology-based peer exchange network(OPEN)

Hui Dong, Zhimin Wang, Robert A. Morris, Jun Huang
2007 2007 International Symposium on Collaborative Technologies and Systems  
Peer-to-peer systems represent a widely accepted approach to sharing massive data and services among large, diverse and varying sets of nodes in the network.  ...  In this paper, we introduce an overlay network which constructs the logical network topologies using a global ontology and peer ontological characteristics.  ...  In addition to those structural links which reflect logical network topologies, there are semantic links which serve as shortcuts for query routings discovered by past successful query results.  ...

OntoZilla: An Ontology-based, Semi-structured, and Evolutionary Peer-to-Peer Network for Information Systems and Services

Feng-Yuan Chuang, Yuh-Jzer Joung
2007 Proceedings of the 2nd International ICST Conference on Scalable Information Systems  
Therefore, a query belonging to a specific concept can be routed to the suitable group of peers in a systematic way, thus supporting efficient concept search.  ...  In OntoZilla, peers supporting the same concept are grouped into the same cluster, and the relationships between clusters are modeled according to the concepts they specialize in.  ...  Using semantic links to reflect the relationships among peers, queries can be routed to the peers with suitable information or services in a systematic way.  ...

Distributed Semantic Overlay Networks [chapter]

Christos Doulkeridis, Akrivi Vlachou, Kjetil Nørvåg, Michalis Vazirgiannis
2009 Handbook of Peer-to-Peer Networking  
Semantic Overlay Networks (SONs) have been recently proposed as a way to organize content in peer-to-peer (P2P) networks.  ...  As a result, less peers need to be contacted, in order to answer a query.  ...  In this respect, a P2P network is organized into SONs, in order to enable efficient routing of queries only to relevant peers.  ...

Using taxonomies for content-based routing with ants

Elke Michlmayr, Arno Pany, Gerti Kappel
2007 Computer Networks  
This paper presents SemAnt, a distributed content-based routing algorithm based on the Ant Colony Optimization meta-heuristic and adapted for deployment in peer-to-peer networks.  ...  Although the ant metaphor has been successfully applied to routing of data packets both in wireless and fixed networks, little is known yet about its appropriateness for search in peer-to-peer environments  ...  SemAnt uses a probabilistic model, in which every query leaves a small trace in the overlay network, and the summation of all traces can be used for subsequent queries as a hint which link to follow in  ...
