The Logical Foundations Of Evidential Reasoning
The approach proposed by Carnap for the development of logical bases for probability theory is investigated by using formal structures that are based on epistemic logics. Epistemic logics are modal…

How To Clear A Block: A Theory Of Plans
Problems in commonsense and robot planning are approached by methods adapted from program synthesis research; planning is regarded as an application of automated deduction. To support this approach, we introduce…

Inferring Domain Plans In Question-Answering
The importance of plan inference in models of conversation has been widely noted in the com-putational-linguistics literature, and its incorporation in question-answering systems has enabled a range of cooperative behaviors.…

On The Imaging Of Fractal Surfaces
We examine the imaging of standard Brownian Fractal surfaces.

A Representation Of Parallel Activity Based On Events, Structure, and Causality
Most AI domain representations have been based on state-oriented world models. In this paper we present an event-based model that focuses on domain events (both atomic and nonatomic) and on…

Evidential Reasoning For Geographic Evaluation For Helicopter, Route Planning
In order to plan operations where knowledge of significant elements is imprecise and uncertain, a means of characterizing the situation in terms of the various factors that may influence those…

Hierarchical Warp Stereo
This paper describes a new technique for use in the automatic production of digital terrain models from stereo pairs of aerial images.
-
Automating Argument Construction
Over the past five years the Artificial Intelligence Center at SRI has been developing a new technology to address the problem of automated information management within real-world contexts. The result…
-
An Architecture For Intelligent Reactive Systems
Any intelligent system that operates in a moderately complex or unpredictable environment must be reactive — that is, it must respond dynamically to changes in its environment. A robot that…
-
An Algorithm For Generating Quantifier Scopings
The syntactic structure of a sentence often manifests quite clearly the predicate-argument structure and relations of grammatical subordination. But scope dependencies are not so transparent. As a result, many systems…

Epipolar-Plane Image Analysis: A Technique For Analyzing Motion Sequences
A technique for unifying spatial and temporal analysis of an image sequence taken by a camera moving in a straight line is presented. The technique is based on a "dense"…

Shading Into Texture
The fractal surface model provides a formalism that is competent to describe such natural 3-D surfaces and, in addition, is able to predict human perceptual judgments of smoothness versus roughness.
