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…

Reduced Resolution Residual Coding for H.264-Based Compression System
This paper describes a macroblock-based mixed resolution video encoding system. By reducing the spatial resolution of some macroblock residuals intelligently, our preliminary experiments show up to 20% improvement in video…

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…

Joint Segmentation and Classification of Dialog Acts in Multiparty Meetings
This paper investigates a scheme for joint segmentation and classification of dialog acts (DAs) of the ICSI Meeting Corpus based on hidden-event language models and a maximum entropy classifier for…

Deductive Discovery and Composition of Resources
We consider the problem of answering a query, where the answer is not provided explicitly by any one resource, but has to be deduced from information provided by many resources;…
