Situation Description Language

Abstract

SDL is a Situation Description Language intended for use in situation assessment problems. SDL provides knowledge modelling and inference facilities for reasoning with information. The SDL includes an object-oriented data model with single inheritance. It provides a forward-chaining inference system using a RETE-based pattern matcher. SDL includes special data types to deal with time, space, and uncertainty. A hypothesis system allows the system to deal with multiple concurrent hypotheses in a systematic way. This document provides details required by programmers or knowledge engineers intending to use the SDL system.
