Summary

Due to the dramatically increasing amount of available data, effective and scalable solutions for data organization and search are essential. Distributed solutions naturally provide promising alternatives to standard centralized approaches. With the computational power of thousands or millions of computers in clusters or P2P systems, the challenges that arise are manifold, ranging from efficient resource discovery to load balancing issues and distributed ranking problems.

This workshop will provide space for researchers to discuss these problems and to define new directions for the work on distributed information retrieval. We will also encourage submissions of position papers, experiences, software demonstrations and posters in the area of distributed information retrieval.

Program

The workshop takes place in Room Cabernet (Grand Ballroom) on October 30, 2008, from 8am to 1pm. Each presentation takes 15 minutes + 5 minutes for questions. The detailed program is below:

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.

This workshop continues the efforts from previous workshops.

Topics

Topics of interest include, but are not limited to:

Workshop chairs

Steering Committee

Program Committee

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 format. 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). Submitted papers will undergo a peer review process by at least three members of the program committee.

Full papers accepted for publication will be included in the proceedings published by ACM. Manuscripts should be formatted using the ACM camera-ready templates. Camera-ready instructions are available here.

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

Papers have to be submitted electronically in printable PDF format (other formats will be rejected) via the online submission system.

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.
