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.

Problem Solving Tactics
This paper describes the basic strategies of automatic problem solving, and then focuses on a variety of tactics for improving their efficiency.

Computational Models Of Beliefs and The Semantics Of Belief-Sentences
We present a semantic interpretation for belief sentences and show how this interpretation overcomes some of the difficulties of alternative approaches, especially those based on possible-world semantics.

Focusing and Description In Natural Language Dialogues
This paper describes focusing mechanisms based on domain structure clues which have been included in a computer system and, from this perspective, indicates future research problems entailed in modeling the focusing process more generally.

Hierarchical Representation Of Three-Dimensional Objects Using Verbal Models
We present a formalism for the computer representation of three-dimensional shapes, that has as its goal to facilitate man-machine communication using verbal, graphic, and visual means. With this method, pieces may be assembled hierarchically using any of several ways of specifying attachment.

Map-Guided Interpretation Of Remotely-Sensed Imagery
Geometric correspondence between a sensed image and a symbolic reference map is established in an initial stage of processing by adjusting parameters of a sensor model so that image features predicted from the map optimally match corresponding features extracted from the sensed image.

A (14C) Deoxyglucose Study of Somatosensory and Associated Cortical Areas in the Monkey
The strategies used by the macaca monkey brain in controlling the performance of a reaching movement to a visual target have been studied by the quantitative autoradiographic 14C-DG method.

Deafnet
National telecommunications system raises awareness within the deaf community of email’s potential.

Prospects For Industrial Vision
This paper builds a case for needed additional levels of representation and outlines the design of a general-purpose computer-vision system capable of high performance in a wide variety of industrial vision tasks.

Why Is Discourse Coherent?
In this paper, it is argued that coherence can be characterized in terms of a set of ‘coherence relations’ between segments of a discourse. It is shown, from an abstract description of the discourse situation, that these relations correspond to the kinds of communicative work that needs to get done in discourse.

Natural Language Access To A Melanoma Data Base
This paper describes ongoing research towards developing a system that will allow physicians personal access to patient medical data through natural language queries to support both patient management and clinical research.

Coherence and Coreference
In this paper, formal definitions are given for several coherence relations, based on the operations of an inference system; that is, the relations between successive portions of a discourse are characterized in terms of the inferences that can be drawn from each.
