Task Support on the Semantic Web

S. Potter, A. Tate and J. Dalton, AIAI, School of Informatics, University of Edinburgh, UK

  • Semantic Web Task Support

  • The coordination of resource and activity is a key task in modern organizations - and the Semantic Web will provide increased opportunities for interaction.

  • With this increase comes a greater need for support in managing collaborative activity.

  • I-X technology provides support for mixed-initiative collaborations:

    • Founded on <I-N-C-A> (Issues, Nodes/activities, Constraints, Annotations) ontology.

    • I-X tool suite provides viewers, domain managers and editors, messaging tools, etc, to allow issues to be resolved and activities performed.

  • Example 2: Search and Rescue (SAR)

  • Upon learning of downed aviator, SAR coordinator downloads appropriate SOP.

  • Description of emergency locale – including available medical facilities – found on web as DAML-O ontologies and knowledge bases.

  • An I-Q agent provides reasoning interface to these resources to identify appropriate hospitals for treating aviator.

  • DAML-S matchmaker provides link to ‘in the field’ agents:

    • SAR resources – helicopters, patrol boats, etc – advertised as services.

    • Another I-Q agent constructs and sends queries to matchmaker and interprets results for coordinator.

  • Environment allows coordinator to construct and implement effective rescue plan.

Workshop Organization Support

Process Panel

  • Example 1: Workshop Organization

  • Environment includes downloadable standard operating procedures (SOPs), along with human and computer helper agents.

  • A ‘Triplestore’ repository of RDF facts provides up-to-date domain knowledge.

  • The Organize Workshop SOP provides a decomposition of the task and links to helper agents – for instance:

    • Using RDQL queries to retrieve Triplestore facts, an I-Q agent is able to identify the major players in different fields.

    • The known capability of this agent ensures it is suggested when a relevant sub-task (‘identify steering committee’) becomes the focus of activity.
