The MINERVA Project: Towards Collaborative Search in Digital Libraries Using Peer-to-Peer Technology
[chapter]
2005
Lecture Notes in Computer Science
Preserved Fulltext
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. ...

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 ...

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] . ...

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. ...

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. ...
