Experimental Robot Psychology
Here I propose an approach that I call it experimental robot psychology because it involves formalizing and reasoning about the design of existing robot agents. It shows promise of yielding…

The Structures Of Discourse Structure
This paper presents the basic elements of a computational theory of discourse structure that simplifies and expands upon previous work. It is concerned with answers to two rather simple questions:…

One-Eyed Stereo: A Unified Strategy To Recover Shape From A Single Image
In this paper we contend that the distinct assumptions made in each of these schemes must be tantamount to providing a second (virtual) image of the original scene, and that…

Reference and Denotation: The Descriptive Model
This paper deals with a specific approach to the problem of reference that I call the descriptive model. In particular, I am going to examine some relations between this model…

On Some Formal Properties Of Metarules
Grammars contain rules for generating sentences. Metarules are statements about these rules. They are metagrammatical devices that can be used to generate rules of the grammar or to encode certain…

Constraints On Order
A modified linear precedence (LP) component of Generalized Phrase Structure Grammar (GPSG) is proposed that accommodates partially free word order. In the revised framework, LP rules are sets of LP…

Evaluation Of Stereosys Vs. Other Stereo Systems
SRI International is implementing a complete, state-of the-art stereo system that will produce dense three-dimensional (3D) data from stereo pairs of intensity images. This system forms a framework for much…

The Stereo Challenge Data Base
As previously reported in Fischler [1984] and Hannah [1984], SRI International is implementing a complete, state-of-the-art stereo system that will produce dense three-dimensional (3-D) data from stereo pairs of intensity…

Linear Precedence In Discontinuous Constituents: Complex Fronting In German
It is shown that the current framework of Generalized Phrase Structure Grammar (GPSG) is not suited for describing the interaction of leftward extractions, scrambling, and constraints on linear order.

Formal Theories Of Knowledge In AI and Robotics
The machine is regarded as knowing a fact if its state either explicitly encodes the fact as a sentence of an interpreted formal language or if such a sentence can…

More Notes From The Unification Underground: A Second Compilation Of Papers On Unification-Based Grammar Formalisms
We study a new corpus of patient-clinician interactions recorded when patients are admitted to a hospital for suicide risk and again when they are released.

Criteria For Designing Computer Facilities For Linguistic Analysis
We discuss several aspects of computer use that are preeminent in establishing the utility for linguistic research of computer tools and describe several factors that must be considered in designing…
