Call for Participation

LSDS-IR 2011
The 9th International Workshop on
Large-Scale and Distributed Systems for Information Retrieval
Co-located with ACM CIKM'11 (October 28, 2011)
Glasgow, United Kingdom

Invited Talks:
- Aristides Gionis (Yahoo! Research), "Efficient algorithms for large-scale social dissemination"
- K. Selcuk Candan (Arizona State University), "RanKloud: Scalable multimedia and social media retrieval and analysis in the cloud"

Research Papers:
- George Tsatsaronis, Matthias Reimann, Iraklis Varlamis, Orestis Gkorgkas, Kjetil Nørvåg, "Efficient community detection using power graph analysis"
- Jan Sedmidubsky, Vlastislav Dohnal, Pavel Zezula, "On investigating scalability and robustness in a self-organizing retrieval system"
- Yasemin Avcular, Torsten Suel, "Scalable manipulation of archival web graphs"
- Ke Zhou, Ronan Cummins, Mounia Lalmas, Joemon Jose, "Evaluating large-scale distributed vertical search"
- Nicola Tonellotto, Craig Macdonald, Iadh Ounis, "Query efficiency prediction for dynamic pruning"
- Veronica Costa, Mauricio Marin, "Approximate distributed metric-space search"

Community Update:
In addition to these presentations, there will be a "community update" session where different research groups will present their recent or on-going works. A representative researcher from each group will make a 10 minute presentation about the works in his/her group. This session will take place before the lunch so that different groups are engaged to potential collaborations during the workshop. The currently scheduled list of presentations include the following researchers/institutions:

Hao Wan, Baidu
Fabrizio Silvestri, ISTI-CNR
Craig Mcdonald, University of Glasgow
Alexander Stupar, Saarland University
B. Barla Cambazoglu, Yahoo! Research Barcelona
Jan Sedmidubsky, Masaryk University
Veronica Gil-Costa, Yahoo! Research Latin America
Iraklis A. Klampanos, University of Glasgow

The entire technical program and more details are available at

Aims & Topics of Interest:
The growth of the Web and user bases lead to important performance problems for large-scale distributed information retrieval systems. Scalability and efficiency of these systems also have an impact on their effectiveness. As the premium venue on the topic, the LSDS-IR'11 workshop aims to bring together high-quality research contributions on scalable and efficient large scale IR systems. The workshop also hosts contributions that propose different ways of leveraging diversity and multiplicity of resources available in distributed systems. The topics of interest include, but are not limited to:

- applications of cloud computing to IR
- IR algorithms on novel computing architectures (GPUs, etc.)
- distributed crawling, indexing, and query processing
- large-scale multimedia IR
- heterogeneous resources and data integration
- P2P approaches in distributed and personalized IR
- search engine caching and replication in large scale systems
- standards and benchmarks for large scale and distributed IR
