Teoretická část:
Získat základní přehled v oblasti modelování dialogu, zejména co se týče přístupu k managementu dialogu a reprezentaci kontextu. Získat podrobný přehled v problematice zajištění vzájemného porozumění a modelování tohoto procesu prostřednictvím verifikačních a klarifikačních sub-dialogů v existujících dialogových systémech. Vyhodnotit vhodnost a použitelnost stávajících modelů pro použití v situovaném systému. Navrhnout potřebné úpravy, případně rozšířit stávající modely o aspekty situované komunikace. Praktická část: Seznámit se s architekturou systemu COSY-Explorer a zde používanými nástroji. Zejména CAST (The CoSy Architecture Schema Toolkit), DFKI modul pro komunikaci v přirozeném jazyce (COMSYS) a Brennerův plánovač včetně simulačního prostředí (MAPSIM). Integrovat plánovač v rámci modulu COMSYS. Implementovat verifikační a klarifikační strategie prostřednictvím plánovacích operátorů, s využitím možnosti kontinuálního plánování. Realizovat rozhraní mezi plánovačem a ostatními částmi modulu COMSYS zajišťujícími interpretaci vstupu a generování výstupu. Podle potřeby realizovat aktualizaci reprezentace kontextu. |

Preliminary scope of work |
The domain for the thesis is spoken situated dialogue for human-robot
interaction. Characteristic for such dialogue, as with any spoken dialogue, is that the involved dialogue participants may fail to understand each other. This may regard what is being said, or how what is said refers to the situation(s) the dialogue is about. To resolve uncertainty and/or break-downs in conversation, participants typically resort to phrasing clarification requests. The goal of the thesis is to develop a continuous planning-based approach to handle clarification for communicative grounding. Planning will enable the formulation of a dialogue plan to address a clarification need, and monitor the execution of that plan. (We assume this need may be raised by the robot or by a human user.) Should the plan (or the dialogue based on it) fail to fully address the need, the continuous nature of the approach will make it possible to adapt the plan until the intended goal has been achieved. The resulting steps in the dialogue plan should provide input to a existing utterance content planner. Within the scope of this thesis, resources will be formulated for this content planner to turn dialogue plan action steps into logical forms of utterance content. The work for this thesis will be based in existing approaches to clarification and communicative grounding. Theoretically, the thesis is to extend this work to cover situated dialogue. Practically, the thesis work is to yield an implementation integrated into an existing system for spoken situated dialogue in human-robot interaction. |
