Practical Natural-Language Processing by Computer
This paper describes the state of the art in practical computer systems for natural-language processing. We consider why one would want to use natural language to communicate with computers at…

The Database As Model: A Metatheoretic Approach
This paper presents a method of formally representing the information that is available to a user of a relational database. The intended application area is deductive question-answering systems that must…

An Inference Technique for Integrating Knowledge from Disparate Sources
This paper introduces a formal method for integrating knowledge derived from a variety of sources for use in "perceptual reasoning". The formalism is based on the "evidential propositional calculus"- a…

Recognizing Intended Meaning and Speakers’ Plans
This paper presents a new model for recognizing the speaker's intended meaning in determining a response.
-
A Simple Sensor to Gather Three-Dimensional Data
In this paper straightforward procedures are presented for calibrating a camera, computing the equation of a plane, and combining a camera calibration and an equation of a light plane to…

Artificial Intelligence: Engineering, Science Or Slogan?
This paper presents the view that artificial intelligence (AI) is primarily concerned with propositional languages for representing knowledge and with techniques for manipulating these representations.

Computational Strategies For Analyzing The Organization and Use Of Information
A program of research is presented that is producing systems that make it possible to study the organization and use of information and, at the same time, provide more effective…
-
Deductive Synthesis Of The Unification Algorithm
The task of deriving a unification algorithm automatically is beyond the power of existing program synthesis systems. We will identify some of the capabilities required of a theorem-proving system to…
-
Machine Learning for Information Management
The core idea is that of a compiler system that can hold a conversation with a user in English about his specific domain of interest, subsequently retrieve and display information…
-
Natural-Language Processing Part One: The Field In Perspective
The intent of the authors is to demonstrate that natural-language processing techniques are useful now, to reveal the richness of the computations performed by human natural-language communicators, and to explain…
-
Knowledge-Engineering Techniques and Tools in the Prospector Environment
Techniques and tools to assist in several phases of the knowledge-engineering process for developing an expert system are explored.

Random Sample Consensus: A Paradigm for Model Fitting with Applications to Image Analysis and Automated Cartography
A major portion of this paper describes the application of RANSAC to the Location Determination Problem (LDP): Given an image depicting a set of landmarks with known locations, determine that…
