Cooperative Plan Reasoning for Dialogue Systems
نویسندگان
چکیده
For several years, we have been studying collaborative, dialogue-based interaction between humans and between humans and a computer system as part of the TRAINS project [Allen and Schubert, 1991]. The goal of the project is an intelligent planning assistant that is conversationally proficient in natural language and that will assist a human manager (the user) formulate and execute plans. The domain of discourse is a transportation world that includes trains, cities, connections between them, warehouses and factories, and different types of commodities, all of which are part of a simulated world in which the mutually-decided-upon plans are executed. Work in the TRAINS project consists of developing both formal models of the various tasks involved in collaborative dialogue and programs that implement these theories. Both will be described in this report. This work is of direct relevance to all three stated areas of interest for the symposium:

Generic Plan Recognition for Dialogue Systems
We describe a general framework for encoding rich domain models and sophisticated plan reasoning capabilities. The approach uses graph-based reasoning to address a wide range of tasks that typically arise in dialogue systems. The graphical plan representation is independent of but connected to the underlying representation of action and time. We describe types of plan recognition that are neede...
متن کاملThe Architecture of a Cooperative Respondent
If natural language question-answering (NLQA) systems are to be truly effective and useful, they must respond to queries cooperatively, recognizing and accommodating in their replies a questioner's goals, plans, and needs. Transcripts of natural dialogue demonstrate that cooperative responses typically combine several communicative acts: a question may be answered, a misconception identified, a...
متن کاملInteroperability and Knowledge Representation in Distributed Health and Fitness Companion Dialogue System
As spoken dialogue systems move beyond task oriented dialogues and become distributed in the pervasive computing environments, their growing complexity calls for more modular structures. When different aspects of a single system can be accessed with different interfaces, knowledge representation and separation of low level interaction modeling from high level reasoning on domain level becomes i...
متن کاملGoal Formulation based on Communicative Principles
The paper presents the Constructive Dialogue Model as a new approach to formulate system goals in intelligent dialogue systems. The departure point is in general communicative principles which constrain cooperative and coherent communication. Dialogue participants are engaged in a cooperative task whereby a model of the joint purpose is constructed. Contributions are planned as reactions to the...
متن کاملA Temporal Argumentation Approach to Cooperative Planning Using Dialogues
In this paper, we study a dialogue-based approach to multi-agent collaborative plan search in the framework of t-DeLP, an extension of DeLP for defeasible temporal reasoning. In t-DeLP programs, temporal facts and rules combine into arguments, which compare against each other to decide which of their conclusions are to prevail. By adding temporal actions for multiple agents to this argumentativ...
