Semantic Network Representation In Rule Based Inference System
Rule-based inference systems allow judgmental knowledge about a specific problem domain to be represented as a collection of discrete rules. We describe a rule-based system that uses a partitioned semantic…

Procedures for Integrating Knowledge in a Speech Understanding System
This paper describes the procedures for integrating knowledge from different sources in the SRI speech understanding system. The system uses these contextual constraints in assigning priorities to alternative interpretations, combining…
-
Human Engineering For Applied Natural Language Processing
Human engineering features for enhancing the usability of practical natural language systems are described. Such features include spelling correction, processing of incomplete (elliptical) inputs, interrogation of the underlying language definition…

Language Access To Distributed Data With Error Recovery
This paper discusses an effort in the application of artificial intelligence to the access of data from a large, distributed data base over a computer network. A running system is…
-
Lifer Manual: A Guide To Building Practical Natural Language Interface
This document describes an application-oriented system for creating natural language interfaces between existing computer programs (such as data base management systems) and casual users. The system is easy to use…

Interactive Aids For Cartography and Photo Interpretation
In this report, the application areas of ARPA-supported Machine Vision work at SRI were changed to Cartography and Photointerpretation. This change entailed general familiarization with the new domains, exploration of…

Hendrix’s Model for Simultaneous Actions and Continuous Processes: An Introduction and Implementation
This paper presents a self-contained introduction and implementation description to a simulation system for modeling simultaneous action and continuous processes.

Parametric Correspondence and Chamfer Matching: Two New Techniques for Image Matching
Parametric correspondence is a technique for matching images to a three dimensional symbolic reference map. An analytic camera model is used to predict the location and appearance of landmarks in…

LIFER: a Natural Language Interface Facility
This note describes LIFER, a practical facility for creating natural language interfaces to other computer software. Emphasizing human engineering, LIFER has bundled natural language specification and parsing technology into one…
-
Application Of Interactive Scene Analysis Techniques To Cartography
This paper proposes an interactive graphically generated method for delineation of cartographic and cultural features on a map.

Perceptual Strategies For Purposive Vision
This report describes a computer program that approaches perception as a problem-solving task. The system uses information about the appearances of objects, about their interrelationships, and about available sensors to…

Experiments In Speech Understanding System Control
The main experiment tested the effects on performance of four major choices: focus attention by inhibition or use an unbiased best-first method, ``island-drive’’ or process left or right, use context…
