Machine-processable Descriptions for interop and
automation
Grid and Pervasive share issues in large scale
distributed systems. e.g. service description,
discovery, composition autonomic computing.
These can be aided with semantics.
Pervasive applications need the Grid, e.g.
Sensor Networks
Grid applications need Pervasive Computing e.g.
Smart Laboratory

Envisense

• The Centre for Pervasive Computing in the
  Environment is one of the seven national centres
  in the DTI Next Wave Technologies and Markets
  Programme
• Current projects FloodNet, GlacsWeb and SECOAS

Medical Devices
Sensor bus

• ECG, Oxygen saturation
• Body movement
• Accelerometers
• GPS

GPS aerial
16
Blood Glucose Monitoring

• Self-reporting - Patient takes measurement
• Measurement sent via mobile phone to remote
  infrastructure
• Series of lifestyle questions asked as part of
  the clinical trial
• Users promoted for compliance
• Current trial involves 100 patients

Two infrastructure enablers

• On demand transparently constructed
  multi-organisational federations of distributed
  services
• Distributed computing middleware
• Computational Integration

Semantics in and on the Grid
23
Semantics in e-Science
Ontology-aided workflow construction

• RDF-based service and data registries
• RDF-based metadata for experimental components
• RDF-based provenance graphs
• OWL based controlled vocabularies for database
  content
• OWL based integration

RDF-based semantic mark up of results, logs,
notes, data entries

CombeChem Semantic Datagrid

• Existing datastores linked by RDF triplestores
• Around 80 million triples in 3store
• A social experiment! e.g. Chemists built
  ontology for units
• Chemists appreciate powerful queries and
  flexibility
• Metadata infrastructure is in place

Reflections

• This is about the intersection of the digital and
  physical worlds
• Proof of concept
• Best practice is emerging through case studies
  in the wild
• Lots still to be done the real world is messy!
• Information perspective
• Anticipated vs. unanticipated re-use
• Key principle is Semantic Annotation
• Capture contextual metadata at source
• Maintain provenance
• Can use Semantic Web technologies
