We developed Planet as part of our work in the DARPA High Performance Knowledge Bases (HPKB) program. Planet is a middle-level theory that represents planning knowledge. We worked with personnel from Cycorp to integrate Planet into CYC, which resulted in an extension to the CYC IKB.

We used Planet to develop a system for Course of Action (COA) Critiquing for the DARPA HPKB Battlespace Challenge Problem.

We have demonstrated using Planet in this approach to integration in our work on the Rosetta project, an ISO Technology Integration Experiment between High Performance Knowledge Bases and Control of Agent-Based Systems exploring ontology-based agent communication. We also use Planet in our work on a problem-solving method for plan evaluation (see here for details).

Planet is available in Loom, KIF, and CycL. Send email to Jim Blythe (blythe@isi.edu) or Yolanda Gil (gil@isi.edu) if you would be interested in seeing the latest version.
