Enabling Knowledge Discovery Services on Grids

The Grid is mainly used today for supporting highperformance compute intensive applications. However, it is going to be effectively exploited for deploying data-driven and knowledge discovery applications. To support this class of applications, high-level tools and services are vital. The Knowledge Grid is an high-level system for providing Grid-based knowledge discovery services. These services allow professionals and scientists to create and manage complex knowledge discovery applications composed as workflows that integrate data sets and mining tools provided as distributed services on a Grid. They also allow users to store, share, and execute these knowledge discovery workflows as well as publish them as new components and services. This paper presents and discusses how knowledge discovery applications can be designed and deployed on Grids. The contribute of novel technologies and models such as OGSA, P2P, and ontologies is also discussed.
