Interactive Games, Dialogues and the Verbalization

This note is devoted to an interactive game theoretic formalization of dialogues as psycholinguistic phenomena and the unraveling of a hidden dialogue structure (the “verbalization”) of 2-person differential interactive games. In the field-theoretic description of interactive games the dialogues are defined näıvely as interactive games of discrete time with intention fields of continuous time; the correct mathematical formulation of such definition is proposed. The states and the controls of a dialogue correspond to the speech whereas the intention fields describe the understanding. In the case of dialogues the main inverse problem of interactive game theory is to describe geometrical and algebraical properties of the understanding. On the other hand, a precise mathematical definition of dialogues allows to formulate a problem of the unraveling of a hidden dialogue structure of any 2-person differential interactive game. Such procedure is called the verbalization. It means that the states of a differential interactive game are interpreted as intention fields of a hidden dialogue and the problem is to describe such dialogue completely. If a 2-person differential interactive game is verbalizable one is able to consider many linguistic (e.g. the formal grammar of a related hidden dialogue) or psycholinguistic (e.g. the dynamical correlation of various implications) aspects of it.
