  • Interpreting Natural-Language Utterances In Dialogs About Tasks

    This paper describes the results of a three-year research effort investigating the knowledge and processes needed for participation in natural-language dialogs about ongoing mechanical-assembly tasks.

  • Random Sample Consensus: A Paradigm for Model Fitting with Applications to Image Analysis and Automated Cartography

    RANSAC is capable of interpreting/smoothing data containing a significant percentage of gross errors, and is thus ideally suited for applications in automated image analysis where interpretation is based on the data provided by error-prone feature detectors.

  • A D-Ladder User’s Guide

    D-LADDER (DIAMOND-based Language Access to Distributed Data with Error Recovery) is a computer system designed to provide answers to questions posed at the terminal in a subset of natural language regarding a distributed data base of naval command and control information. The system accepts natural-language questions about the data.

  • Diagram: A Grammar For Dialogues

    This paper presents an explanatory overview of a large and complex grammar, DIAGRAM, that is used in a computer system for interpreting English dialogue.

  • The Interpretation Of Verb Phrases In Dialogs

    Presented and discussed are the kinds of knowledge necessary for interpreting references to actions, as well as algorithms for using that knowledge in interpreting dialog utterances about ongoing tasks and for drawing inferences about the task situation that are based on a given interpretation.

  • Crisis In Ushasa: A Simulation Activity For Government Classes

  • Metaphor, Metaphor Schemata, and Selective Inferencing

    Three examples of metaphors are examined in detail in this light–a simple metaphor, a spatial metaphor schema, and a novel metaphor.

  • Conversation As Planned Behavior

    In this paper, a framework for investigating conversation, which for convenience will be called the Planning Approach, is developed from this hypothesis. It suggests a style of analysis to apply to conversation, analysis in terms of the participants’ goals, plans, and beliefs, and it indicates a consequent program of research to be pursued.

  • Natural Language Processing

    Natural Language Processing

    PARC, which is now part of SRI, invented computational linguistic technologies based on understanding the structure of language.

  • Handling Complex Queries In A Distributed Data Base

    As part of the continuing development of the LADDER system, we have substantially expanded the capabilities of the data base access component that serves as the interface between the natural-language front end of LADDER and the data base management systems on which the data is actually stored.

  • Theoretical Foundations Of Linguistics and Automatic Text Processing

    The interdisciplinary research required to design such systems have a common center, conceptually, in the development of new kinds of lexical information, since words are not only linguistics objects, they are also psychological objects that evoke experiences from which meanings can be inferred.

  • An Iconic Transform For Sketch Completion and Shape Abstraction

    This paper shows how a simple label propagation technique, in conjunction with some novel ideas about how labels can be applied to an image to express semantic knowledge, lead to the simplification of a number of diverse and difficult image analysis tasks.
