The main goal of our work in this area is to investigate how ontologies help in agent coordination and communication. In the EXPECT framework, agents can be viewed as entities with some problem-solving capability that need to be brought together in order to solve more complex problems. This work is joint with ISI's Loom/Powerloom project.
1. Finding Agents
This work addresses the issue of how to match requests and agent capabilities through ontologies. The hypothesis is that a broad and shallow ontology (such as the HPKB upper ontology or SENSUS) is sufficient for locating agents. This work builds on EXPECT's matcher to find capabilities of problem-solving methods that match a given problem-solving goal.
2. Ontology-Based Agent Communication
Once you have found agents with the right capability (for example through Phosporus), then they need to use richer ontologies for communicating with each other. For this work, we will be using ontologies and tools that we are developing under the HPKB program. These include the PLANET ontology for representing plans, and the Ontomorph ontology mapping toolkit.
