37. 37 What is introduced: (A): object (screw; terminologically round head bolt) (B): direction (screwing bolt into port from designated top of fuselage) Dialogue example & situation c'td Introduction

38. 38 What is introduced: (A): object (screw; terminologically round head bolt) (B): direction (screwing bolt into port from designated top of fuselage) Observations: 1.Cooperativity: Inst and Cnst produce a directive together. Stages in (A) : Inst starts production of an indirect speech act. Cnst wants to contribute the object-NP. Similarly in (B): Inst demands a put-through-action. Cnst contributes the direction-AvP. Dialogue example & situation c'td Introduction

39. 39 2.Repair-construction in (A): Inst adds repair to Cnst’s contribution. Repair-construction can be seen as a sub-dialogue initiated by Inst and completed by Cnst’s reply. Dialogue example & situation c'td Introduction

40. 40 2.Repair-construction in (A): Inst adds repair to Cnst’s contribution. Repair-construction can be seen as a sub-dialogue initiated by Inst and completed by Cnst’s reply. 3. Repair ++ : Confirmation of contribution of Cnst’s by Inst and extension of contribution (in B). Confirmation can be seen as a sub-dialogue initiated by Inst and completed by Cnst’s reply. Motivation for sub-dialogue assumption: (A) and (B) can basically be seen as two conjoined speech acts etc.; precond., grounding Dialogue example & situation c'td Introduction

Motivation for sub-dialogue assumption: (A) and (B) can basically be seen as two conjoined speech acts etc.; precond., grounding 4. Coordination: Inst and Cnst have to coordinate their grammar. Especially clear from (A).  Cnst continues production (application of rule) of Inst’s. Dialogue example & situation c'td Introduction

43. 43 5. Common knowledge concerning the domain: Inst and Cnst have common knowledge concerning the properties of objects like bars, bolts, nuts, and aggregates 6. Common knowledge of how to produce a stable bolt-nut- combination. Hence: Cnst can complete speech act on the basis of such knowledge. Additional source of common knowledge: aggregate built so far.

Recognition of intention on part of Cnst’s: Believe(Cnst, intend(Inst, intend(Cnst, take (Cnst, bolt)))) 10.Cooperativity on part of Cnst due to recognition of intention. Cnst takes over intention of Inst’s: intend(Cnst, take (Cnst, bolt) Similarly for the (B)-case. Dialogue example & situation c'td Introduction
