Semantic Grid Research Group (SEM-GRD) - Mailing list archive
The goal of the Semantic Grid Research Group (SEM-GRD) is to realise the added value of Semantic Web technologies for Grid users and developers. We provide a forum to track Semantic Web community activities and advise the Grid community on the application of Semantic Web technologies in Grid applications and infrastructure, to identify case studies and share good practice. Tasks:

Track semantic web activities and inform the Grid community on what tools and ideas to use now and which to watch

Provide a forum to discuss and share best practice in 'semantic grid' projects

Create links with other RG and WG to both push Semantic Grid expertise and to offer a service of expertise. For example, participation in the proposed working group on scheduling ontology

Operate a community web portal

Encourage engagement between the Grid and Semantic Web communities
In due course we plan to produce a primer (document and Web Site) to help Grid developers find out about and make use of Semantic Web technologies. This web page is a collection links to documents and sites which we believe may be useful in this regard.

Grid Scheduling Ontology Working Group (GSO-WG): a concrete instantiation of an ontology.
The working group will create an ontology of the Grid Scheduling domain (usage and hierarchy of terms from the Grid Scheduling Dictionary) supporting the scheduling of Grid resources done by local and distributed instances of software subsystems like schedulers, brokers or corresponding Grid services. The ontology will overcome the shortcomings of a dictionary allowing classification of schedulers, reasoning about schedulers or mapping semantics of different scheduling systems for example. Using the ontology generated by the working group when designing and implementing the next generation of Resource Management Systems and their corresponding Grid services may further lead to ontology-driven systems.

Cognitive Grids: Cognitive grids aim to provide intelligent middleware for Grid computing infrastructure. Our work uses a wide-range of AI technology to improve current Grid middleware, such as planning techniques to generate job workflows for execution in a Grid environment, ontology-based matchmaking for computing resources, reasoning about meta-data to automate the composition of distributed problem-solving components based on the user's desired end products, and dynamic planning and scheduling techniques for robust execution of job workflows.

Knowledge Grid (papers list, ppt): in our project Knowledge Grid, an environment for the design and deployment of grid-based distributed data mining applications, we are developing a two layer metadata system:

		An ontology for the Data Mining domain, in DAML+OIL (RDF Schema) plus a DAML API-based tool for the browsing and querying of the ontology, that will be used to assist the designer of the data mining application over of the Knowledge Grid
		A set of metadata describing specific information about installed data sources to be mined, data mining software, extraction tools and so on, that is used when accessing the installed resources

Current work regards the development of a reasoning system over the ontology, in future we plan to introduce such an approach in the authoring system of Grid-based Problem Solving Environments.
