Matthias Bender, Sebastian Michel, Christian Zimmer, Gerhard Weikum
2005 Lecture Notes in Computer Science  
Experiments with the MINERVA prototype testbed study the benefits and costs of P2P search for keyword queries.  ...  We consider the problem of collaborative search across a large number of digital libraries and query routing strategies in a peer-to-peer (P2P) environment.  ...  We have implemented the outlined method in the MINERVA testbed for P2P search.  ...

p2pDating: Real life inspired semantic overlay networks for Web search

Josiane Xavier Parreira, Sebastian Michel, Gerhard Weikum
2007 Information Processing & Management  
In the spirit of the natural notion of autonomous peers participating in a P2P system, our strategy creates semantic overlay networks based on the notion of "peer-to-peer dating": Peers are free to decide  ...  We show how we can greatly benefit from these additional semantic relations during query routing in search engines, such as MINERVA, and in the JXP algorithm, which computes the PageRank authority measure  ...  INTRODUCTION The peer-to-peer (P2P) approach, which has become popular in the context of file-sharing systems such as Gnutella or KaZaA, allows handling huge amounts of data in a distributed and self-organized  ...

Sebastian Michel, Matthias Bender, Peter Triantafillou, Gerhard Weikum
2006 Lecture Notes in Computer Science  
Finally, we conduct a performance evaluation in MINERVA, our prototype P2P Web search engine.  ...  A pivotal issue when designing a peer-to-peer (P2P) Web search engine in this environment is query routing: selecting a small subset of (a potentially very large number of relevant) peers to contact to  ...  P2P Web search has emerged as a new topic only recently. A variety of ongoing research projects are pursuing this direction [2, 37, 4, 14, 15, 30, 36, 22] , including our MINERVA project [5] .  ...

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  
Early experiments indicate that our approach significantly decreases the number of peers that have to be involved in a query to reach a certain level of recall and, thus, decreases user-perceived latency  ...  However, very few of them take into consideration the overlap between peers: as the most popular resources (e.g., documents or files) are often present at most of the peers, a large fraction of the documents  ...  Section 4 presents the architecture of MINERVA, our distributed P2P search engine that was used for our experiments.  ...

Peer-to-peer similarity search over widely distributed document collections

Christos Doulkeridis, Kjetil Nørvåg, Michalis Vazirgiannis
2008 Proceeding of the 2008 ACM workshop on Large-Scale distributed systems for information retrieval - LSDS-IR '08  
Such an application is retrieval of the top-k most similar documents in a widely distributed document collection, as in the case of digital libraries.  ...  This paper addresses the challenging problem of similarity search over widely distributed ultra-high dimensional data.  ...  Some research focuses on providing P2P web search functionalities, like in [15] , where MINERVA∞ is presented, a P2P web search engine that aims at scalability and efficiency.  ...

Distributed Large-Scale Information Filtering [chapter]

Christos Tryfonopoulos, Stratos Idreos, Manolis Koubarakis, Paraskevi Raftopoulou
2014 Lecture Notes in Computer Science  
In the P2P architecture that we envision, resources are annotated using attribute-value pairs, where value is of type text and queried using constructs from Information Retrieval (IR) models.  ...  We study the problem of distributed resource sharing in peer-to-peer networks and focus on the problem of information filtering.  ...  a similar spirit, [49] discusses the feasibility of Web search in a P2P environment and estimates the difficulty of the problem.A straightforward approach to support Boolean searching in P2P networks  ...

Databases, Information Systems, and Peer-to-Peer Computing  
In this paper, we investigate the effectiveness of different database selection and result merging methods in the scope of P2P Web search engine Minerva.  ...  We adapt existing measures for database selection and results merging, all directly derived from popular document ranking measures, to address the specific issues of P2P Web search.  ...  These considerations induced us to launch the Minerva project [1] , a P2P Web search engine. In Minerva, each peer has its own collection of crawled or personal documents.  ...
