Compositionality for Tightly Coupled Systems: a New Application of the Propositions-As-Types Interpretation
Although compositional techniques are being successfully employed in practice, the use of such techniques is often rather informal and intuitive, and typically a justification for correct behaviour of the composed…

Conflict Negotiation Among Personal Calendar Agents
We will demonstrate distributed conflict resolution in the context of personalized meeting scheduling. The demonstration will show how distributed constraint optimization can be used to facilitate interaction between cognitive agents…

Computer-Mediated Collaborative Reasoning and Intelligence Analysis
We introduce a framework spanning the entire collaborative thought process using the Angler and SEAS (Structured Evidential Argumentation System) applications. Angler encourages creative brainstorming while SEAS demands analytical reasoning. The…

Combining Prosodic, Lexical and Cepstral Systems for Deceptive Speech Detection
We report on machine learning experiments to distinguish deceptive from nondeceptive speech in the Columbia-SRI-Colorado (CSC) corpus. Specifically, we propose a system combination approach using different models and features for…
