Evaluating profiling and query expansion methods for P2P information retrieval

Hans Friedrich Witschel, Thomas Böhme
2005 Proceedings of the 2005 ACM workshop on Information retrieval in peer-to-peer networks - P2PIR'05  
Experiments with different profile building and query expansion methods show that compression of profiles is possible without losing too much retrieval performance and that query expansion using global  ...  This paper addresses the issue of peer profiles, i.e. compact representations of a peer's locally offered content, and their use in P2P information retrieval and routing.  ...  CONCLUSIONS By analysing various techniques for profiling and query expansion in P2P information retrieval and applying them to structure building and searching, we found support for our claim that query  ...

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  
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.  ...  This paper experimentally studies approaches to the problem of ranking information resources w.r.t. user queries in peer-to-peer information retrieval.  ...  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.  ...

Models and Algorithms of Information Retrieval in a Multilingual Environment on the Basis of Thematic and Dynamic Text Corpora

Aleksey A. Mamchich
2016 Cybernetics and Information Technologies  
The developed algorithms provide the effectiveness of documents information retrieval and notable for universality, i. e., for the independence from topics.  ...  Models and algorithms of information retrieval in the global and local computer networks on the basis of thematic and dynamic text corpora are proposed in this article.  ...  Taking into account that p1P(t 1)  p2P(t 2), let us define the retrieval criterion : (Tin)  (Zin)  R in the following way: for any text t  Tin and any query z  Zin ((t), (z)) = p2P((t, z)  ...

Applying Hebbian Theory to Enhance Search Performance in Unstructured Social-Like Peer-to-Peer Networks

Chester S.J. Huang
2012 ETRI Journal  
First, using the social relation weight, the query peer stores and searches for the appropriate response peers in social-like p2p networks.  ...  To address this issue, previous researchers explored the possibility of building efficient p2p networks by clustering peers into communities based on their social relationships, creating social-like p2p  ...  Thus, this method is relatively inefficient for collecting and storing relevant information on the content of other peers in social-like p2p networks.  ...

Emerging semantic communities in peer web search

R. Akavipat, L.-S. Wu, F. Menczer, A.G. Maguitman
2006 Proceedings of the international workshop on Information retrieval in peer-to-peer networks - P2PIR '06  
To achieve good results for a text query, a peer search system must try to predict which peers are best suited for the query.  ...  The best candidates for the query are the peers whose content is semantically closest to the query. Several studies confirm this observation [8, 27, 31] .  ...  Acknowledgments We are grateful to the Nutch Organization for its open source search engine code and to the Open Directory Project for the data used to model our simulated users.  ...

SEIF: Search Enhanced by Intelligent Feedback in Unstructured P2P Networks

Xiaoyu Yang, Yiming Hu
2009 2009 International Conference on Parallel Processing  
To improve the performance of similarity search and information retrieval is an important research issue in peer-to-peer environment.  ...  In this paper, we propose a distributed architecture for enhancing the performance of similarity search in unstructured P2P networks.  ...  Another future work is to propose different policies for evaluating the relevance of peers to queries and the different methods for measuring a node's satisfaction to the query results.  ...

User modeling for information retrieval has mostly been studied to improve the effectiveness of information access in centralized repositories.  ...  Our approach models a user's persistent, long-term interests based on past queries, and uses the model to improve search efficiency for future queries that represent interests similar to past queries.  ...  In the following section we describe related work on user modeling for information filtering, Web retrieval and federated search in P2P networks.  ...

On the Usage of Global Document Occurrences in Peer-to-Peer Information Systems [chapter]

Odysseas Papapetrou, Sebastian Michel, Matthias Bender, Gerhard Weikum
2005 Lecture Notes in Computer Science  
There exist a number of approaches for query processing in Peer-to-Peer information systems that efficiently retrieve relevant information from distributed peers.  ...  We argue that the additional effort to create and maintain the GDO information is reasonably low, as the necessary information can be piggybacked onto the existing communication.  ...  Information Retrieval Basics Information Retrieval (IR) systems keep large amounts of unstructured or weakly structured data, such as text documents or HTML pages, and offer search functionalities for  ...
