In this paper we present a new personalized approach, which integrates a social profile into
a distributed search system. Most previous studies on distributed information retrieval are …

Selective search is a distributed retrieval technique that reduces the computational cost of
large-scale information retrieval. By partitioning the collection into topical shards, and using …

Clinical Decision Support Systems (CDS) are built to make biomedical literature efficiently
accessible to clinicians. The typical queries submitted to these systems are medical cases …

Resource Selection (or Query Routing) is an important step in P2P IR. Though analogous to
document retrieval in the sense of choosing a relevant subset of resources, resource …

We consider the problem of resource selection in clustered Peer-to-Peer Information
Retrieval (P2P IR) networks with cooperative peers. The clustered P2P IR framework …

Conventional web search engines are centralised in that a single entity crawls and indexes
the documents selected for future retrieval, and the relevance models used to determine …

There are three challenges for a meta-search engine to form the final results. The
challenges are the resource representation, resource selection and result merging. The …

Information retrieval technique assists us to extract information from a huge amount of
information sources. Web search engine is a typically commercial system implementing …

This work is located in the domain of distributed information retrieval (DIR). A simplified view
of the DIR requires a multi-search in a set of collections, which forces the system to analyze …

The search engine discussed in this paper is a directory search engine. It is used to solve
issues of cache and performance optimization. It provides website search services for …
