Semantic dialogue modeling

This paper describes an abstract model for the semantic level of a dialogue system. We introduce mathematical structures which make it possible to design a semantic-driven dialogue system. We describe essential parts of such a system, which comprise the construction of feature-values relations representing meaning from a given world model, the modeling of the flow of information between the dialogue strategy controller and speech recogniser by a horizon of comprehension and the horizon of recognition results, the connection of these horizons to wordings via utterance-meaning pairs, and the incorporation of new horizons into a state of information. Finally, the connection to dialogue strategy controlling is sketched.

A Fock Space Toolbox and Some Applications in Computational Cognition.

We present a Matlab toolbox, called “FockBox”, handling Fock spaces and objects associated with Fock spaces: scalars, ket and bra vectors, and linear operators. We give brief application examples from computational linguistics, semantics processing, and quantum logic, demonstrating the use of the toolbox.
