Abstract

This is a midterm report of the third year of BBN's ongoing effort in Knowledge Representation for Natural Language Understanding. Previous reports have been quarterly and have contained a brief technical summary of quarterly progress followed by one or more technical articles describing some aspect of the project. Starting with this report, we will be changing this practice so that technical articles will be issued as separate reports and semiannual progress reports will provide brief technical progress summaries. In this report, we give a brief overview of the objectives of the project followed by a summary of recent progress. 1

INTRODUCTION

This is a midterm report of the third year of BBN's ongoing effort in Knowledge Representation for Natural Language Understanding. Previous reports have been quarterly and have contained a brief technical summary of quarterly progress followed by one or more technical articles describing some aspect of the project. Starting with this report, we will be changing this practice so that technical articles will be issued as separate reports and semiannual progress reports will provide brief technical progress summaries. In this report, we give a brief overview of the objectives of the project followed by a summary of recent progress.

1. OVERVIEW

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. In such situations, not only does the commander need certain information in order to make his decisions effectively, but in complex situations, this requires the presentation of that information in a form that is matched to the abilities of human comprehension.

RESEARCH IN KNOWLEDGE REPRESENTATION FOR NATURAL LANGUAGE UNDERSTANDING

The underlying assumption of this work is the following: 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 conven...
