The authors argue that utterances, like physical actions, seem coherent when an observer can link them to a shared overall goal. They propose treating speech acts as planning operators. Each operator has preconditions and effects, and those effects fall mainly on… 4. **[Signalling the Interpretation of Indirect Speech Acts](https://md.research.elamur.ai/free/en/papers/cohen-1980-signalling-interpretation-indirect-speech-acts/)** *(1980 · 1 citation)* This short ACL 1980 panel paper asks how plan-based theories of speech acts can be checked against real dialogue. ## All works 8 works of theirs in our library, the most cited first; 4 with a page here, the others link their original until we summarise them. 1. **[Elements of a Plan-Based Theory of Speech Acts ↗](https://doi.org/10.1207/s15516709cog0303_1) Cognitive Science 3(3):177–212 · no summary yet**Philip R.
