Experimental Evaluation of Subject Matter Expert-oriented
R. Schrag, M. Pool, Vinay K. Chaudhri, R.C. Kahlert, J. Powers, Philip R. Cohen, J. Fitzgerald, & S. Mishra

We describe a large-scale experiment in which non-artificial intelligence subject matter experts - with neither artificial intelligence background nor extensive training in the task - author knowledge bases following a challenge problem specification with a strong question-answering component.

Fast Parallel Surface Interpolation With Applications To Digital Cartography
Richard Szeliski

The manipulation of two dimensional elevation maps is an important part of digital cartography. In many situations, these maps are computed by interpolating sparse data such as isolated elevation points obtained from stereo matching.

Formal Constraints On Metarules
Stuart M. Shieber, Susan U. Stucky, Hans Uszkoreit, & Jane J. Robinson

Metagrammatical formalisms that combine context-free phrase structure rules and metarules (MPS grammars) allow concise statement of generalizations about the syntax of natural languages.

Getting on the Same Page using Scenario-Based Learning: An Alignment of Education and Industry Goals for Technician Education
Carolyn Dornsife, Geneva Haertel, Bladimir Lopez-Prado, Eric Snow, & Louise Yarnall

This report examines how community college and industry experts rated a problem-based learning curriculum. The report indicates that industry experts and instructors diverge in their expectations about how "real-world," problem-based learning curriculum needs to be.

IDA: An Intelligent Data Access Program
Daniel Sagalowicz

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 the data base itself.

Image-To-Image Correspondence: Linear-Structure Matching
Grahame B. Smith, & Helen C. Wolf

We examine the task of matching images of a scene when they are taken from very different vantage points, when there is considerable scale change, and when the image orientations are unknown.

Interpretation As Abduction
Jerry R. Hobbs, Mark E. Stickel, Douglas E. Appelt, & Paul Martin

Abduction is inference to the best explanation. In the TACITUS project at SRI we have developed an approach to abductive inference, called "weighted abduction," that has resulted in a significant simplification of how the problem of interpreting texts is conceptualized.

Language Access To Distributed Data With Error Recovery
Earl D. Sacerdoti

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 described that provides access to multiple instances of a data base management system over the ARPANET in real time.
