Call For Papers

7th Workshop on Large-Scale Distributed Systems for Information Retrieval (LSDS-IR'09)

The Web is continuously growing. Currently, there are more than 20 billions pages (some sources suggest 100 billions), compared to less than 1 billion documents in 1998. Traditionally, Web-scale search engines employ large and highly replicated systems, operating on computer clusters in one or few data centers. Coping with the increasing number of user requests and indexable pages requires adding more resources. However, data centers cannot grow indefinitely. Scalability problems in information retrieval have to be addressed in the near future, and new distributed applications are likely to drive the way in which people use the Web. Distributed IR is the point in which these two directions converge. This workshop will provide space for researchers to discuss these problems and to define new directions for the work on distributed information retrieval.

Workshop Activities and Goals
The workshop aims to bring together researchers from the domains of IR and databases working on peer-to-peer information systems and to foster closer collaboration that could have a large impact on future research directions in the area of distributed and P2P IR.

Topics of interest include, but are not limited to:
*Novel P2P IR applications/architectures
*Retrieval models for distributed and P2P IR
*Heterogeneous distributed data integration and organization
*Query routing in distributed environments
*Distributed ranking
*Distributed index structures
*Efficiency in distributed and P2P IR
*Scalability of distributed indexing and retrieval
*Multimedia retrieval for distributed and P2P IR
*Distributed indexing and retrieval of dynamic information sources
*Standards / benchmarks for P2P IR
*Grid IR
*Decentralized reputation management
*Distributed data provenance
*Tools for distributed IR

Workshop Format
The workshop solicits scientific papers that address problems specific to IR in heterogeneous and distributed environments. Additionally, position papers outlining interesting new research domains and approaches are welcome. The selection of papers is based primarily on their potential to influence future research. Papers have to present original contributions not concurrently submitted elsewhere.

Paper Submission
Papers should not exceed 8 pages, double column, including figures, tables and references in the standard ACM Conference style (for LaTeX, use the "Option 2" style). Papers have to present original research contributions not concurrently submitted elsewhere, and must be submitted electronically in printable PDF format (other formats will be rejected) via the online submission system. Submitted papers will undergo a peer review process by at least three members of the program committee.

At least one author of an accepted paper must register for the workshop. Registration must be done at the time when the author sends the camera-ready copy of the paper.

Best papers will be considered for publication on a special issue of an international journal.

Important Dates
Paper submission: June 15, 2009
Notification: June 27, 2009
Camera-ready papers: July 4, 2009
Workshop date: July 23, 2009
