  • Some Remarks on the Place of Logic in Knowledge Representation

    What is the place of logic in knowledge representation? It is argued that the answer to this question depends on what one means by logic.

  • An Abstract Prolog Instruction Set

    This report describes an abstract Prolog instruction set suitable for software, firmware, or hardware implementation. The instruction set is abstract in that certain details of its encoding and implementation are left open, so that it may be realized in a number of different forms.

  • Planning English Referring Expressions

    This paper describes a theory of language generation based on planning. To illustrate the theory, the problem of planning referring expressions is examined in detail. A theory based on planning makes it possible for one to account for noun phrases that refer, that inform the hearer of additional information, and that are coordinated with the…

  • Metarules as Meta-Node-Admissibility Conditions

    Meta-rule phrase structure grammars (MPS grammars ) have been shown to be an extremely powerful formalism in need of constraints from both the computational and the linguist points of view.

  • A Laser Scanner for Solder Joint Imaging

    This report gives a preliminary account of the construction of a low-cost laser system for providing data on defective solder joints on printed circuit boards.

  • The Relax Image Relaxation System: Description and Evaluation

    The purpose of the IU Testbed is to provide a means for transferring technology from the DARPA-sponsored program to DMA and other organizations in the defense community.

  • Applied Logic – It’s use and implementation as a programming tool

    The ideas are illustrated by describing in detail one sizable prologue program which implements a simple compiler the advantages and practicability of using prologue for real compiler implementation are discussed.

  • Telegram: A Grammar Formalism For Language Planning

    The TELEGRAM system described in this paper solves this problem by annotating a unification grammar with assertions about how grammatical choices are used to achieve various goals, and by enabling the planner to augment the functional description of an utterance as it is being unified.

  • The Relationship Between Image Irradiance and Surface Orientation

    A formulation of shape from shading is presented in which surface orientation is related to image irradiance without requiring detailed knowledge of either the scene illumination or the albedo of the surface material.

  • Providing A Unified Account Of Definite Noun Phrases In Discourse

    This paper focuses on the use of various referring expressions such as definite noun phrases and pronouns and examines their interaction with mechanisms used to maintain discourse coherence.

  • Applied Logic and Its Use and Implementation As A Programming Tool

    The first part of the thesis explains from first principles the concept of “logic programming’’ and its practical application in the programming language Prolog.

  • A Prolegomenon to Situation Semantics

    An attempt is made to compare Computational Linguistics with Situational Semantics.
