A General, Abstract Model of Incremental Dialogue Processing

Abstract

We present a general model and conceptual framework for specifying architectures for incremental processing in dialogue systems, in particular with respect to the topology of the network of modules that make up the system, the way information flows through this network, how information increments are ‘packaged’, and how these increments are processed by the modules. This model enables the precise specification of incremental systems and hence facilitates detailed comparisons between systems, as well as giving guidance on designing new systems. In particular, the model can serve as a framework for specifying module communication in such systems, as we illustrate with some examples.
