Content distribution networks (CDNs) increase the capacity of individual Web sites and attempt to deliver content from caches that are located “closer” to end-users than the origin servers that provide the content. CDN brokering provides CDNs a way to interoperate by allowing one CDN to intelligently redirect clients dynamically to other CDNs. This paper describes the goals, architecture, and p...

At present many outsourcing organizations need sharing of the information via on-demand access. Information Brokering System (IBS) have been already proposed to connect large-scale loosely-federated data sources via brokering overlay. But there are some attacks with these traditional IBS, namely attribute-correlation attack and inference attack. To overcome these attacks here we are proposing t...

Query reenement in information retrieval over repositories on the Web faces problems when trying to adapt a purist database approach. Needed semantics and brokering facilities diier signiicantly when compared, for instance, with traditional SQL-like query schemes. Therefore, we propose an interaction model, adapted to Web sources, and based on constraints and on the notion of so-called \virtual...

Recent emerging technologies such as internetworking and the World Wide Web (WWW) have signiicantly expanded the types, availability, and volume of data accessible to an information management system. In this new environment it is imperative to view an information source at the level of its relevant semantic concepts. We propose that these semantic concepts be chosen from pre-existing domain sp...

Existing knowledge base resources have the potential to be valuable components of the Semantic Web and similar knowledge-based environments. However, from the perspective of these environments, these resources are often under-characterised, lacking the ontological characterisation that would enable them to be exploited fully. In this chapter we discuss a technique which can be applied to identi...
