We have developed a method and prototype program for assisting two experts in their attempts to construct a single, consensus knowledge base. We show that consensus building can be effectively facilitated by a debugging approach that identifies, explains, and resolves…

This report elucidates the linguistic representation of temporal relations among events. This involves examining sentences that contain two clauses connected by words like once, by the time, when, and before. Specifically, the effect of the tenses of the connected clauses…

This paper addresses the problem of recovering relative structure, in the form of an invariant, referred to as projective structure, from two views of a 3D scene. The invariant structure is computed without any prior knowledge of camera geometry, or…

The design of the control laws governing the behavior of individual agents is crucial for the successful development of cooperative agent teams. These control laws may utilize a combination of local and/or global knowledge to achieve the resulting group behavior.…

In this note we discuss how recognition can be achieved from a single 2D model view exploiting prior knowledge of an object's structure (e.g. symmetry). We prove that for any bilaterally symmetric 3D object one non- accidental 2D model view…

A key problem in model-based object recognition is selection, namely, the problem of determining which regions in the image are likely to come from a single object. In this paper we present an approach that extracts and uses color region…

This study surveyed the sexual behaviors and knowledge of Acquired Immunodeficiency Syndrome (AIDS) among 117 undergraduate students from McGill University, Montreal. The sample consisted of 32 men and 85 women ranging from 18 up to 24 years of age. The…

This research examined the influence of ability, prior knowledge and knowledge of text structure on expository history text corpora comprehension using a quasi-representative research paradigm. Sixty grade eight students participated in two history units. Hypotheses that ability, prior knowledge and…

The effect of schooling on nutritional knowledge, attitudes and nutritional outcomes in Ethiopia was investigated. Data were obtained in late 1989 in Debre Birhan in Shoa province from three groups: 267 mothers, 114 clinic users and six primary schools with…
