Oatlal delxls In the r e p o r t of problem solving as reflec~ir~ an underlying allocation of effort (or attention). Pew errors occur with problem elements that •re given processing effort, while constraints that •re given little attention are more often violated. %n this way, these reports are reflecting changes Zn the organization of the problem element• that occur over the course of reaching a solution. | DRSIGN FOR DIALOGUE COMPREHENSION William c. Mann use Information Sciences Institute Marina del Rev CA April 1979 This paper describes aspects of the design of a dialogue comprehension system DCS currently being Implemented. It concentrates on a few design Innovations rather than the description of the whole system. The three areas of innovation discussed are 1. The relation of the DCS design to speech Act theory and Dialogue Game theory 2. Design assumptions about how to identify the best interpretation among several alternatives and a method called Preeminence Scheduling for implementing those assumptions 3. A new control structure Hcarsay-3 that extends the control structure of llearsay-II and makes Preeminence Scheduling fairly straightforward. I. Dialogue Games Speech Acts and DCS -- Examination of actual human dialogue reveals structure extending over several turns and corresponding to particular issues that the participants raise and resolve. Our past work on dialogue has led to an account of this structure. Dialogue Game theory Levin Moore 1978 Moore Levin Mann 1977 This theory claims that dialogues and other language uses as well are comprehensible only because the participants are making available to each other the knowledge of the goals they are pursuing at the moment. Patterns of these goals recur representing language conventions their theoretical representations are called Dialogue Games. If a speaker employs a particular Dialogue Game that fact must be recognized by the hearer if the speaker is to achieve the desired effect. In other words Dialogue Game recognition is an essential part of dialogue comprehension. Invoking a game Is an act and terminating the ongoing use of a game is also an act. Dialogue game theory has recently been extended Mann 1979 in a way makes those game-related acts explicit Acts of Bidding a game. Accepting a bid and Bidding termination are formally defined as speech acts comparable to others In speech act theory. So for .
