Communication channels physically constrain the flow and shape of human language just as irresistably as a river bed directs the river’s current. Escarpments speed the current, sculpting jetties and whirlpools. Meadows encourage evenness, a certain recumbency.
A new form of abduction—least specific abduction—is proposed as being more appropriate to the task of interpreting natural language than the forms that have been used in the traditional diagnostic and design-synthesis applications of abduction.
P-PATR is a compiler for unification-based grammars that is written in Quintus Prolog running on a Sun 2 workstation. P-PATR is based on the PATR-II formalism developed at SRI International. PATR is a simple, unification-based formalism capable of encoding a wide variety of grammars.

An architecture for a rational agent must allow for means-end reasoning, for the weighing of competing alternatives, and for interactions between these two forms of reasoning.
A new coarse-coding technique is presented for labeling image pixels and regions to match exemplars or multivariate material signatures. This multinomial classification method can be used for object cuing and tracking, as well as for material identification and image segmentation.
The KNIFE segmentation algorithm interleaves splitting and merging of regions during mono-chrome or multiband image partitioning. KNIFE splits regions along object boundaries, thus avoiding rectangular quadtree artifacts and establishing a context for good statistical decisions.
This manual describes Rex, a programming language for specifying machines by declaratively describing their behavior. The Rex language consists of a set of Lisp functions that define primitive Rex machines and provides methods for building complex machines out of simpler components.
This report surveys literature and research in the field of distributed artificial intelligence (DAI) and provides an overview of computer architectures particularly suited to such research.
