Generating and Revising Hierarchical Multi-turn Text Plans in an ITS
نویسندگان
چکیده
CIRCSIM-Tutor v. 3 is a natural-language based ITS for cardiac physiology. In this paper, we describe TIPS, a new text planning engine for CIRCSIM-Tutor based on current research in text generation. Since conversations cannot be completely planned in advance, TIPS plans and executes iteratively. It maintains a goal hierarchy for the tutor while carrying on a conversation with the student. It can handle multi-turn plans on the part of the tutor, and it can back up and replan when the student gives an unexpected answer. In this paper we sketch the design of TIPS using an analysis of human-to-human tutoring transcripts to shape the requirements.

The Behavior-Oriented Design of Modular Agent Intelligence
Behavior-Oriented Design (BOD) is a development methodology for creating complex, complete agents such as virtual-reality characters, autonomous robots, intelligent tutors or intelligent environments. BOD agents are modular, but not multi-agent systems. They use hierarchical reactive plans to perform arbitration between their component modules. BOD provides not only architectural specifications...
متن کاملInterdiction problem as a tool to identify an effective budget allocation to quality improvement plans
In the face of budgetary limitations in organizations, identifying critical facilities for investing in quality improvement plans could be a sensible approach. In this paper, hierarchical facilities with specified covering radius are considered. If disruption happens to a facility, its covering radius will be decreased. For this problem, a bi-objective mathematical formulation is proposed. Crit...
متن کاملRobot Plans During Their Execution
We describe how our planner, xfrm, carries out the process of anticipating and forestalling execution failures. xfrm is a planning system that is embedded in a simulated robot performing a varying set of complex tasks in a changing and partially unknown environment. xfrm revises plans controlling the robot while they are executed. Thus whenever the robot detects a contingency, xfrm projects the...
متن کاملUsing a Reactive Planner as the Basis for a Dialogue Agent
This paper describes APE (the Atlas Planning Engine), the reactive planner at the center of the Atlas dialogue management system. The goal of Atlas is to build conversation-based systems, where turns in the “conversation” may include graphical actions and/or text. Since APE can be used to generate a dialogue involving arbitrarily nested discourse constructs, it is more powerful than dialogue pl...
متن کاملUncertainty analysis of hierarchical granular structures for multi-granulation typical hesitant fuzzy approximation space
Hierarchical structures and uncertainty measures are two main aspects in granular computing, approximate reasoning and cognitive process. Typical hesitant fuzzy sets, as a prime extension of fuzzy sets, are more flexible to reflect the hesitance and ambiguity in knowledge representation and decision making. In this paper, we mainly investigate the hierarchical structures and uncertainty measure...
