A Network-Based Knowledge Representation and Its Natural Systems
We describe a knowledge representation scheme called K-NET and a problem solving system called SNIFFER designed to answer queries using a K-NET knowledge base. K-NET uses a partitioned semantic net…

A Production System For Automatic Deduction
A new predicate calculus deduction system based on production rules is proposed. The system combines several developments in Artificial Intelligence and Automatic Theorem Proving research including the use of domain-specific…

The Representation and Use Of Focus In Dialogue Understanding
This report develops a representation of focus of attention that circumscribes discourse contexts within a general representation of knowledge. To formalize the notion of focus, the need for and the…

A Framework For Speech Understanding
This paper reports the author’s results in designing, implementing, and testing a framework for a speech-understanding system. The work was done as part of a multi-disciplinary effort based on state-of-the-art…

Managing Network Access to a Distributed Database
This paper describes a program, FAM – for File Access Manager –, used to access to data distributed over a computer network. FAM is a part of a system which…

The Representation and Use of Focus in a System for Understanding Dialogs
As a dialog progresses, the objects and actions that are most relevant to the conversation, and hence in the focus of attention of the dialog participants, change. This paper describes…

IDA: An Intelligent Data Access Program
IDA was developed at SRI to allow a casual user to retrieve information from a data base, knowing the fields present in the data base, but not the structure of…
-
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…

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…
-
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…
