Title: Communicative Agents for Spatio-Temporal Reasoning Workbench (CoASTeR-WB)
Agency / Branch: DOD / NAVY
Contract: N00014-10-M-0150
Award Amount: $69,561.00


Currently there are no software platforms for developing and evaluating reusable, virtual, communicative spatio-temporal agents. This makes rapid development and meaningful comparative evaluation, critical requirements for military and non-military applications, infeasible. Lack of such a platform also slows down the much needed research in spatio-temporal technologies. We will architect a software workbench called CoASTeR-WB (Communicative Agent for Spatio-Temporal Reasoning) to meet these requirements. In contrast to the state-of-the-art technologies that use disparate and proprietary representation and reasoning technologies, we will investigate a unique framework for plug-and-play open-source virtual worlds and communicative technologies and reusable spatio-temporal reasoning agents. We will investigate automatic methods for achieving semantic interoperability among CoASTeR-WB components. We will investigate the use of a cognitive architecture as a robust foundation for developing spatio-temporal agents for advanced navigation and extra-navigational tasks. Finally, we will develop specifications for a built-in evaluation framework with a library of spatio-temporal reasoning tasks and annotated scenarios to enable rapid, consistent, and comparative evaluations. We will validate our approach by implementing a proof-of-concept prototype and executing an evaluation run with a library of sample spatio-temporal reasoning test-problems.
