Knowledge Based Workflow Building Architecture Construction Use ontology & ontology service to facilitate method selection & instantiation Advising Use workflow knowledge & workflow services to advise and critique Storage and query Add semantic to databases & workflow automatically, thus facilitate content-based search and query © Geodise Project, University of Southampton, 2002.

© Geodise Project, University of Southampton, 2002. Application Scenario Drag and drop tasks from task ontology Ontology assisted task configuration State monitoring, reasoning and advising based on best practices in the domain Generating executable scripts from the finished workflow found state panel with user_skill_level low in fact list. So Switching ON Advisor... ("fluent_jou_file" "gambit_jou_file") is now available. You may be able to do analysis by using ("fluent_jou_file") but still need input:("mesh_file") mesh can produce the resource mesh_file © Geodise Project, University of Southampton, 2002.

Deployment of the Knowledge Advising System Service orientated workflow advising mechanism Conceptual level of the knowledge base is maintained by using ontology XML used in middleware for easy data transference Rule based reasoning of system state using JESS © Geodise Project, University of Southampton, 2002.
