A Task-Specific Ontology for Design and Execution of time-oriented skeletal plans Academic Article uri icon

abstract

  • : Skeletal plans are a powerful way to reuse existing domain-specific procedural knowledge while leaving room for execution-time flexibility. Generic plan schemata can be instantiated and refined dynamically by the executing agent over significant periods of time and in highly dynamic environments. In the Asgaard project, we are investigating a set of tasks that support the execution of skeletal plans by a human executing agent, other than the original plan designing agent. We are developing task-specific problem-solving methods that perform these tasks in multiple clinical domains, given an instance of a clinical guideline plan and an electronic medical patient record. We point out the domain-specific knowledge roles required by each problemsolving method, and present a text-based, machine-readable language, called Asbru, to represent and to annotate execution plans. We represent explicitly the intentions underlying these plans, as temporal patterns to be achieved or avoided....
