“…In some of our own work the importance of integrating hypermedia aspects in an NLcentered system (Stock 1992;Stock & ALFRESCO Team 1993) is emphasized. In sum, integrating NL with hypermedia facilities provides the following advantages:…”

“…Moreover, in multimodality the balance of responsibilities in dialogue can be altered from the one we find in nature. For some cases, in this connection, the active role of the hearer should be enhanced (Stock 1992); in the case presented here in particular something is added to the speaker's part to make the hearer's part easier. Actually in natural dialogues, while the use of anaphora is very convenient for the speaker, the hearer has a much more difficult task in identifying the desired reference; and of course the more so for an artificial NLP system (Cohen 1991).…”

Multimodality is a powerful concept for dealing with dialogue cohesion in a human-computer natural language (NL)-centered system. This work is a modest step toward more effective exploitation of the potentially large bandwidth of communication provided by this situation. The relations between exploration, navigation, and NLbased communication are discussed in general and with reference to two prototypes. Light cognitive load feedback and direct manipulation are proposed so that user and system can cooperate in mutually establishing the structure of the ongoing dialogue. The main points are: (i) use of an appropriate dialogue structure to constrain inference in the anaphora resolution process; (ii) use of a graphical representation of the structure, to limit the problem of opacity; (iii) allowance for the possibility of direct manipulation on this representation, to avoid the necessity of operating linguistically at the metalevel. The context of the work is within NL-centered multimodal information access systems, in which basic entities are pairs (most commonly question and answer). A dialogue model is provided by a modified version of the centering model; it is both sufficiently simple to be displayed in an intuitive fashion on the screen, and sufficiently powerful to give accurate results. An extension of the discourse model, oriented to the treatment of deixis, is also proposed. Finally, steps toward an overall approach to the integration of navigational and mediated aspects of interaction are discussed.
