Domain-Independent Task Specification In The Tacitus Natural Language System
We have defined and implemented a schema specification and recognition language for the TACITUS natural language system. We give examples of the use of this schema language in a diagnostic…
-
Incremental Interpretation
We present a system for the incremental interpretation of natural-language utterances in context. The main goal of the work is to account for the influences of context on interpretation, while…

Introducing The Tileworld: Experimentally Evaluating Agent Architectures
We describe a system called Tileworld, which consists of a simulated robot agent and a simulated environment which is both dynamic and unpredictable. We describe our initial experiments using Tileworld,…

Task-Oriented Dialogues As A Consequence Of Joint Activity
The purpose of this paper to show how a number of difficult-to-explain features of these dialogues follow from the joint or team nature of the underlying task. Specifically, the paper…

Translation By Abduction
This approach overcomes the common machine translation bottleneck by allowing mapping of information from the source to the target language at a variety of levels from the most superficial to…
-
Prosody, Syntax and Parsing
We describe the modification of a grammar to take advantage of prosodic information provided by a speech recognition system. This initial study is limited to the use of relative duration…
-
Backwards Phonology
This paper makes "reversibility" explicit and demonstrates by means of examples from Tunica and Klamath that two-level phonology does have certain desirable capabilities that are not found in grammars of…

Two Principles Of Parse Preference
Our aims in this paper is first to present a compendium of many of these heuristics and secondly to propose two principles that seem to underlie the heuristics.

Interpretation As Abduction
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…

Decision-Making In An Embedded Reasoning System
This paper describes some of the features of a Procedural Reasoning System (PRS) that enables it to operate effectively in such environments.
-
Discovery Learning And Transfer Of Problem Solving Skills
A framework for understanding the effects of discovery learning on the transfer of problem-solving skill is presented.

Real-Time Reasoning: The Monitoring and Control Of Spacecraft Systems
This paper describes research concerned with automating the monitoring and control of spacecraft systems. In particular, the paper examines the application of SRI’s Procedural Reasoning System (PRS) to the handling…
