is a collection of research papers covering a range of topics in expert systems and knowledge engineering. The book is edited by Philip Klahr and the late Donald A. Waterman, both of Rand Corporation. The papers are selected from RAND technical reports published from 1977 to 1985. The book is most valuable to people learning knowledge engineering. Four of… (More)
Knowledge engineering has been successfully applied in many domains to create knowledge-based "expert" systems. We have applied this technology to the area of large-scale simulation and have implemented ROSS, a Rule-Oriented Simulation System, that simulates military air battles. Alternative decision-making behaviors have been extracted from experts and… (More)
Systems that interact in dialogs need to understand linguistic actions being used by one another and know which linguistic actions are appropriate for their own uses. We introduce a model based on conversational action patterns to describe and predict speech acts in natural language dialogs and to specify appropriate actions to satisfy the system's goals. A… (More)
Responding to natural language requires performing two major tasks: information processing (cognition), and decision making (conation). In order to motivate and best guide an entity performing such complex tasks, motivation must originate in the self-interest of the entity. This motivation guides cognitive and conative processes at the lowest possible level… (More)
