Global resources for peer-to-peer text retrieval

Hans Friedrich Witschel
2007 Proceedings of the 30th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '07  
The thesis presented in this paper tackles selected issues in unstructured peer-to-peer information retrieval (P2PIR) systems, using world knowledge for solving P2PIR problems.  ...  A second part of the work will be dedicated to the question of query routing in unstructured P2PIR systems using peer resource descriptions and world knowledge for query expansion.  ...  INTRODUCTION My thesis aims at solving problems in P2PIR for both precision-and recall-oriented retrieval, the guiding question being to what extent global "world" knowledge can be applied in this context  ...

Beyond Term Indexing: A P2P Framework for Web Information Retrieval

Ivana Podnar, Martin Rajman, Toan Luu, Fabius Klemm, Karl Aberer
2006 Informatica (Ljubljana, Tiskana izd.)  
Our goal is to design scalable techniques for building a global key index in structured P2P overlays for large document collections.  ...  Web search over peer-to-peer (P2P) networks shows promise to become an alternative to the state-of-the-art search engines since P2P overlays offer means for decentralized search across widely-distributed  ...  Acknowledgements The work presented in this paper was carried out in the framework of the EPFL Center for Global Computing and supported by the Swiss National Funding Agency OFES as part of the European  ...

Full-text federated search in peer-to-peer networks

Jie Lu

resources work autonomously and collaboratively to accomplish the retrieval task.  ...  Peer-to-peer (P2P) networks integrate autonomous computing resources without requiring a central coordinating authority, which makes them a potentially robust and scalable model for providing federated  ...  Thus we focus on developing solutions to full-text ranked retrieval for federated search of text digital libraries in P2P networks.  ...

SAPIR: Scalable and Distributed Image Searching

Fabrizio Falchi, Mouna Kacimi, Yosi Mass, Fausto Rabitti, Pavel Zezula
2007 International Conference on Semantics and Digital Media Technologies  
In this paper we present a scalable and distributed system for image retrieval based on visual features and annotated text. This system is the core of the SAPIR project.  ...  We show that the combination of content-based and text search on a large scale can dramatically improve the capability of a multimedia search system to answer the users needs and that the Peer-to-Peer  ...  The Peer-to-Peer engine uses the global directory to identify candidate peers that are most likely to provide good query results. More information about MINERVA can be found in [6] .  ...

Top-k Query Evaluation for Schema-Based Peer-to-Peer Networks [chapter]

Wolfgang Nejdl, Wolf Siberski, Uwe Thaden, Wolf-Tilo Balke
2004 Lecture Notes in Computer Science  
Inspired by the success of ranking algorithms in Web search engine and top-k query evaluation algorithms in databases, we propose a decentralized top-k query evaluation algorithm for peer-to-peer networks  ...  Increasing the number of peers in a peer-to-peer network usually increases the number of answers to a given query as well.  ...  Acknowledgements We especially want to thank Kevin Chang from the DAIS group at Urbana-Champaign for giving valuable input to an earlier draft of this report as well as for providing several very useful  ...

Intelligent knowledge discovery in peer-to-peer file sharing

Yugyung Lee, Changgyu Oh, Eun Kyo Park
2002 Proceedings of the eleventh international conference on Information and knowledge management - CIKM '02  
Emerging peer-to-peer computing provides new possibilities but also challenges for distributed applications.  ...  Despite their significant potential, current peer-to-peer networks lack efficient knowledge discovery and management.  ...  Also, if peer hosts in the P2P networks frequently repeat to join and leave, cost for global resource assignment with the key/value pairs will be increased.  ...

Ranking information resources in peer-to-peer text retrieval

Hans F. Witschel
2008 Proceeding of the 2008 ACM workshop on Large-Scale distributed systems for information retrieval - LSDS-IR '08  
This paper experimentally studies approaches to the problem of ranking information resources w.r.t. user queries in peer-to-peer information retrieval.  ...  In distributed environments, for each given user query and a set of information resources that are available, we need to select the right subset of these resources to forward the query to.  ...  ACKNOWLEDGEMENTS I would like to thank Lee Giles for providing the Cite-Seer query log to me and for his prompt reactions to all my enquiries about it.  ...
