Combining CORI and the Decision-Theoretic Approach for Advanced Resource Selection [chapter]

Henrik Nottelmann, Norbert Fuhr
2004 Lecture Notes in Computer Science  
In this paper we combine two existing resource selection approaches, CORI and the decision-theoretic framework (DTF).  ...  Our evaluation shows that precision in the top ranks of this technique is higher than for the existing resource selection methods for long queries and lower for short queries; on average the combined approach  ...  Then, we describe CORI (Sec. 3) and the decision-theoretic framework (DTF, Sec. 4). In Sec. 5, we introduce our new, combined approach for resource selection with CORI and DTF.  ...

Comparing Different Architectures for Query Routing in Peer-to-Peer Networks [chapter]

Henrik Nottelmann, Norbert Fuhr
2006 Lecture Notes in Computer Science  
This paper investigates different building blocks of such architectures, among them the decision-theoretic framework, CORI, hierarchical networks, distributed hash tables and HyperCubes.  ...  Efficient and effective routing of content-based queries is an emerging problem in peer-to-peer networks, and can be seen as an extension of the traditional "resource selection" problem.  ...  Acknowledgements This work is supported by the DFG (grant BIB47 DOuv 02-01, PEPPER).  ...

Decision-Theoretic Resource Selection for Different Data Types in MIND [chapter]

Henrik Nottelmann, Norbert Fuhr
2004 Lecture Notes in Computer Science  
Our approach, decision-theoretic framework (DTF), differs from existing algorithms like CORI in two ways: It computes a selection which minimises the overall costs (e.g. retrieval quality, time, money)  ...  And it allows for other data types beside text (e.g., names, years, images), whereas other resource selection techniques are restricted to text.  ...  Acknowledgements This work is supported by the EU commission under grant IST-2000-26061 (MIND).  ...

Evaluating Document Retrieval Methods for Resource Selection in Clustered P2P IR

Rami Suleiman Alkhawaldeh, Joemon M. Jose, Deepak P
2016 Proceedings of the 25th ACM International on Conference on Information and Knowledge Management - CIKM '16  
This paper empirically benchmarks document retrieval models against the state-ofthe-art resource selection models for the problem of resource selection in the clustered P2P IR architecture, using classical  ...  We observe that semantic heterogeneity is mitigated in the clustered 2-tier P2P IR architecture resource selection layer by way of usage of clustering, and posit that this necessitates a re-look at the  ...  Our empirical analysis indicates that the language modeling approach (LM) should be the preferred resource selection method for both P2P IR and Federated Web Search scenarios; further, BB2 is seen to be  ...

2009 Information retrieval (Boston)  
We describe a number of algorithms for server selection, and consider their effectiveness when collections vary widely in size and are represented by imperfect samples.  ...  In particular, personal metasearch-a novel application of DIR which includes all of a user's online resources-may involve collections which vary in size by several orders of magnitude, and which have highly  ...  Acknowledgements We thank the anonymous reviewers for their helpful comments.

2007 IEEE Data Engineering Bulletin  
We consider the network structure and query processing capabilities of social communities like bookmarks and photo sharing communities such as del.icio.us or flickr.  ...  A common feature of all these networks is that the content is generated by the users and that users create social links with other users.  ...  Here we outline only some straightforward approaches and leave more sophisticated combinations for future work. The goal of peer selection is to identify the top-k peers for a particular query.  ...
