Call for Papers

Peer-to-peer (P2P) systems have emerged as a popular way to share huge volumes of data. The P2P paradigm holds many promises: it couples naturally with the Internet, the universal knowledge and service exchange medium; it favors scalability, by allowing the seamless plugging of data, services and computational resources into the global system; it increases system resilience, by avoiding unique points of failures; it can speed up global access by distributing the indexing and query processing tasks to multiple computing nodes. However, retrieval methods for P2P systems are still at their infancy. P2P networks are prone to congestion when messages are not routed intelligently. Many of the most effective routing or data placement methods developed recently rely on relatively simple retrieval methods and homogeneous network environments.

This workshop will focus on new methods of resource representation, resource selection, and data fusion in peer-to-peer networks. The workshop particularly encourages papers that address heterogeneous peer-to-peer networks (e.g., a variety of data types and service providers), as well as papers about methods that cope with partial and uncertain information. However, more broadly, papers are solicited on any topic related to information retrieval in peer-to-peer networks, including the topics listed below.

• Resource construction methods
• Resource selection
• Query routing
• Data fusion
• Metadata management
• Multimedia retrieval
• Heterogeneous services
• Index structures
• Specific architectures

Goal of the workshop:

This workshop will discuss current retrieval methods of P2P systems, as well as the adaptation of distributed IR methods for P2P systems.

Planned Activities:

• 1-3 invited presentations
• paper presentations by workshop participants
• Closing discussion: P2P IR - achievements and open issues

Submissions:

Authors should submit full papers (not exceeding 5000 words) in PDF format through the online submission tool.
