Grammars and Logics Of Partial Information
This paper is an informal survey of models of grammatical categories in unification-based formalisms from computational linguistics and their relationship to current logic programming concepts. The basic notion of partiality…

Reasoning and Planning In Dynamic Domains: An Experiment With A Mobile Robot
In this paper, the reasoning and planning capabilities of an autonomous mobile robot are described. The reasoning system that controls the robot is designed to exhibit the kind of behavior…
-
Implicature and Definite Reference
An account is given of the appropriateness conditions for definite reference, in terms of the operations of inference and implicature. It is shown how a number of problematic cases noticed…
-
A Logical Approach To Reasoning By Analogy
We analyze the logical form of the domain knowledge that grounds analogical inferences and generalizations from a single instance. The form of the assumptions which justify analogies is given schematically…

The Synthesis Of Digital Machines With Probable Epistemic Properties
Researchers using epistemic logic as a formal framework for studying knowledge properties of artificial-intelligence (AI) systems often interpret the knowledge formula to mean that machine encodes in its state as…

Many Agents Are Better Than One
This paper aims to show how much of the frame problem can be alleviated by using domain models that allow for the simultaneous occurrence of actions and events. First, a…
-
Actions, Processes, and Causality
The purpose of this paper is to construct a model of actions and events that facilitates reasoning about dynamic domains involving multiple agents. Unlike traditional approaches, the proposed model allows…

Stereo Matching By Hierarchical, Microcanonical Annealing
An improved stochastic stereo-matching algorithm incorporates two substantial modifications to an earlier version: a new variation of simulated annealing.

The SRI Mobile Robot Testbed: A Preliminary Report
This paper describes a mobile robot designed for experimentation in artificial intelligence (AI). Presented here are details of the robot?s hardware and software architecture. The robot is driven by two…
-
Persistence, Intention, and Commitment
This paper explores principles governing the rational balance among an agent’s beliefs, goals, actions, and intentions. Such principles provide specifications for artificial agents, and approximate a theory of human action…

Procedural Knowledge
Much of commonsense knowledge about the real world is in the form of procedures or sequences of actions for achieving particular goals. In this paper, a formalism is presented for…
