Abstract

BBN's ARPA project in Knowledge Representation for Natural Language Understanding is aimed at developing techniques for computer assistance to a decision maker in understanding a complex system or situation using natural language control of an intelligent graphics display. The motivating need is that of a military commander in a command and control context both in strategic situation assessment and in more tactical situations -especially in crisis situations. The underlying assumption of this work is that in a crisis situation the commander needs an extremely flexible system, capable of manipulating large amounts of data and presenting it on a graphical display in a variety of ways until the commander feels satisfied that he has a grasp of the situation. Such a system would have abilities to display many kinds of different map overlays, an ability to change the kinds and amounts of detail shown, an ability to conveniently construct unique kinds of displays to suit the situation at hand, as well as the ability to display tabular and graphical information and present textual material in ways that are easily comprehensible.

1. INTRODUCTION

BBN's ARPA project in Knowledge Representation for Natural Language Understanding is aimed at developing techniques for computer assistance to a decision maker in understanding a complex system or situation using natural language control of an intelligent graphics display. The motivating need is that of a military commander in a command and control context both in strategic situation assessment and in more tactical situations -especially in crisis situations. The underlying assumption of this work is that in a crisis situation the commander needs an extremely flexible system, capable of manipulating large amounts of data and presenting it on a graphical display in a variety of ways until the commander feels satisfied that he has a grasp of the situation. Such a system would have abilities to display many kinds of different map overlays, an ability to change the kinds and amounts of detail shown, an ability to conveniently construct unique kinds of displays to suit the situation at hand, as well as the ability to display tabular and graphical information and present textual material in ways that are easily comprehensible.

Techniques to produce such displays on demand, in response to high level specifications of what, they should contain, do not currently exist and will require significant breakthroughs in Bolt Beranek and Newman Inc. Report No. 4513

areas of language understanding, knowledge representation, and knowledge based inference. The work that we have been doing falls into three classes, successively motivated by the initial goal of providing powerful computer assistance to a commander in a complex decision-making task. These areas are: fluent natural language understanding in a graphics context - including helpful systems that go beyond mere passive execution of literal instructions, fundamental
