Semantics in and on the Grid

The Semantic Grid is an extension of the current Grid in which information and services are given well-defined meaning, better enabling computers and peopleto work in cooperation

New ways of discovery: e-Science

• A large part of scientific discovery is now a joint human machine endeavour

• Distributed, collaborative community endeavour

• Virtual organizations include people

• With this will come new ways of accessing and understanding results

• We need new tools and methods to understand the knowledge landscape


Message

Using community to map knowledge

Using knowledge to map community

• e-Science is a distributed, collaborative community endeavour, i.e. virtual organizations

• We need to focus on both…

Butanone dried via silica column andmeasured into 100ml RB flask.

Used 1ml extra solvent to wash outcontainer.

Started reflux at 13.30. (Had tochange heater stirrer) Only reflux

for 45min, next step 14:15.

Inorganics dissolve 2layers. Added brine

~20ml.

Organics are yellowsolution

Washed MgSO4 withDCM ~ 50ml

Future Questions

Whether to have many subclasses of processes or fewer with annotations

How to depict destructive processes

How to depict taking lots of samples

What is the observation/process boundary? e.g. MRI scan

CombeChem Semantic Datagrid• Existing datastores

linked by triplestores• Harvested data• 150 million triples

available, 84 million in store

• Chemists appreciate powerful queries and flexibility

• Metadata infrastructure is in place

• A social experiment! e.g. Chemists built ontology for units

The CS AKTive Space:International Semantic Web Challenge Winner

• 24/7 update of content• Content continually

harvested and acquired against community agreed ontology

• Easy access to information gestalts - who, what, where

• Hot spots– Institutions– Individuals– Topics

• Dynamic Communities of Practice…

• Impact of research– citation services etc– funding levels – Changes and deltas


AKT Community of Practice Tool• Based on the AKT

reference ontology

• Integrates a range of information from different sources – mediated via the ontology

• Can see the CoP change through time

• Can have CoPs of people, projects – any object in the ontology NB FOAF


Summary

• e-Science is a distributed collaborative community endeavour– Community maps knowledge– Knowledge maps community

• Semantic Web technologies facilitate both– Social networks for virtual organizations

• Cyberinfrastructure environments need tools to study and support communities of practice
