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.

A Knowledge-Based Architecture For Organizing Sensory Data
This paper describes an architecture for an information manager that is at the core of a sensor-based autonomous system. The architecture provides the means by which sensor-based data can be…
-
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 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.
-
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…
-
A Morphological Recognizer With Syntactic and Phonological Rules
This paper describes a morphological analyzer which, when parsing a word, uses two sets of rules: describing the syntax of words, and rules describing facts about orthography.
-
Stereo Integral Equation
A new approach to the formulation and solution of the problem of recovering scene topography from a stereo image pair is presented.

A Model Of Plan Inference That Distinguishes Between The Beliefs of Actors and Observers
I describe a model of PI that rests on an analysis of plans as mental phenomena. I show that the content of an appropriate response to a query is affected…
