Instruments

Sensors

and the

Semantic

Grid

David De Roure


Semantic

Pervasive

Grid


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

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

Semantics in and on the Grid

Scientific Instruments and Sensors on the Grid


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

Scientific Instruments and Sensors on the Grid


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

Scientific Instruments and Sensors on the Grid


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
