 **** CALL FOR PAPERS ****

 LSDS-IR 2010
 8th International Workshop on
 Large-Scale Distributed Systems for Information Retrieval

 Friday, July 23, 2010
 University of Geneva, Switzerland
 Co-located with ACM SIGIR 2010 (http://sigir2010.org)

UPDATES (Invited speakers and student grants):

If you are a student and you are interested in attending LSDS-IR 2010,
consider applying for a registration fee waiver. We will be selecting
a few students from all applicants. These scholarships are funded by
Yahoo! Research.
The procedure to apply is simple. First, we require that you are a
student currently enrolled in a graduate program of some university.
Second, we need you to send to lsdsir at ymail.com your resume and a
statement of purpose saying why you believe you’ll benefit from
attending LSDS-IR 2010.
Please send all documents as PDF files, and bundle them with tar
(compressed is fine). The final date for receiving applications is
June 28, 2010.

We are glad to announce that Dr. Abdur Chowdhury, Twitter’s Chief
Scientist will give a keynote talk. Further details will be available
at the Workshop Program web page.


The Web is estimated to contain at least 21 billion Web pages as of
January 2010. In parallel to the growth of the Web, the population of
Web users has also rapidly increased, and the patterns of interaction
of those users with search engines have changed. Today, the main
research challenge is to scale large-scale search engines with the
growth of the Web, without sacrificing
from user satisfaction.

Traditionally, large-scale commercial search engines operate on one or
more data centers, each containing multiple, very large clusters of
computers. Coping with the increasing number of user requests as well
as crawling and indexing more pages requires adding more computational
resources to data centers. There are, however, constraints in the
scalability of such systems, such as financial costs and physical
space constraints. Consequently, distributing the functionality of a
search engine along with improving the utilization of resources in a
single data center becomes of ultimate importance to the success of
future generations of search systems.

Distributed search engines do not only solve the scalability issue,
but they enable new classes of applications that leverage the
distribution of processing units across a geographical area. As
another facet of distributed IR, we are interested in contributions
that propose different ways of using diversity and multiplicity of
resources available in such distributed systems. More specifically, we
are interested in novel applications, models, and architectures that
deal with efficiency and scalability issues as well as data diversity
and community-oriented information sharing.

This workshop aims to bring together both experienced and young
researchers from distributed IR, including work on P2P search and
efficiency of distributed systems for information processing. This
edition of the workshop will favor novel, perhaps even outrageous
ideas as opposed to finished research work, thus strongly encouraging
the submission of position papers in addition to research papers.
Position papers are important to foster discussion upon controversial
and intriguing ideas on new ways of building distributed
infrastructures for information

We thus encourage submissions of position papers in the area of
distributed IR, and we will also accept research papers which have the
potential to generate discussion. Topics of interest will include, but
will not be limited to:

* Novel distributed IR applications
* Web search in the cloud: application of cloud computing to IR
* IR algorithms on novel computing architectures
* Efficiency and scalability in distributed query processing
* Geographically distributed search engines
* Inverted index partitioning and replication models (with
applications to distributed ranking)
* Collection selection and result merging in federated IR
* Distributed Web crawling
* Distributed indexing and retrieval of dynamic information sources
* Search engine caching in large scale systems
* Resource selection and query routing in distributed environments
* Heterogeneous distributed data integration and organization
* Retrieval models for distributed IR Standards and benchmarks for
distributed IR

The authors presenting the most innovative paper will receive the
"Best Idea Award", according to the originality and feasibility of
their contribution.

Paper submission deadline: May 22, 2010
Notification of acceptance: June 25, 2010
Camera ready deadline: July 5, 2010
Workshop date: July 23, 2010

The workshop will accept regular papers and encourages the submission
of position papers as well. Papers should not exceed 5 pages (can be
extended up to 6 pages for regular papers if needed), double column,
including figures, tables and references in the standard ACM
conference format
(http://www.acm.org/sigs/publications/proceedings-templates). Position
papers must rise interesting ideas and intriguing new topics, and they
do not need to include experiments and definitive achievements. Papers
have to present original research contributions not concurrently
submitted elsewhere, and must be submitted electronically in printable
PDF format. Authors should include a sub-title explicitly identifying
their submission as a regular or a position paper. Submitted papers
will undergo a peer review process by at least three members of the
program committee. The review process is single-blind. At least one
author of an accepted paper must register for the workshop.

As for past editions of the workshop, the workshop chairs will
consider the opportunity to
organize a special issue in an international journal with extended
versions of best papers.
