A single two-dimensional image is an ambiguous representation of the three-dimensional world–many different scenes could have produced the same image–yet the human visual system is extremely successful at recovering a qualitatively correct depth model from this type of representation.
The goal of this project was to enable knowledge engineers to construct knowledge bases faster. We investigated two techniques: knowledge reuse and axiom templates. The results were demonstrated by developing a question-answering system for the crisis management challenge problem.
Computational and theoretical linguists and computer scientists interested in the computer processing of natural language have converged on a class of grammar formalisms for describing the well-formedness conditions of natural languages.

This report describes the goals and plans for a five-year project to develop a computer-based system that will serve as an expert consultant to a human apprentice.
Applicability of existing industrial robot systems is limited; truly flexible automation must make use of significant sensory feedback to respond appropriately to each new stimulus. This requires fundamental research in problem solving and the monitoring of plan execution.
A preliminary version of QLISP is described. QLISP permits free intermingling of QA4-like constructs with INTERLISP code. The preliminary version contains features similar to those of QA4 except for the backtracking of control environments.
This paper describes the basic strategies of automatic problem solving, and then focuses on a variety of tactics for improving their efficiency. An attempt is made to provide some perspective on and structure to the set of tactics.

This paper describes the procedures for integrating knowledge from different sources in the SRI speech understanding system. A language definition system coordinates–at the phrase level–information from syntax, semantics, and discourse in the course of the interpretation of an utterance.
Rule-based systems are being applied to tasks of increasing responsibility. Deductive methods are being applied to their validation, to detect flaws in these systems and enable us to use them with more confidence.
