Imagery, Context Availability, Contextual Constraint and Abstractness

چکیده

A constraint-based theory of abstractness was investigated according to which abstractness of entities is a function of (i) perceptual observability and (ii) characteristics of contextual constraints. Participants performed ratings of context availability, imagery, and abstractness for 36 nouns that varied in abstractness and familiarity. The ratings were used to compare the predictions of abstractness ratings by context availability, dual coding theory and the constraint-based approach outlined in this paper. We found that only constraints explain variation of perceived abstractness for abstract concepts, whereas context availability and imagery are good predictors of the dichotomous distinction of concrete-abstract, and of variations of concreteness for concrete concepts only. A second study shows that introspection-based constraints are most critical for abstractness ratings. Implications are discussed.

Contextual Characteristics of Concrete and Abstract Words

In this work we investigate commonalities and differences between the semantic representations of concrete and abstract words using human judgments and distributional semantics. We tackle the following questions: a) Does distributional similarity imply similarity in concreteness vs. abstractness? b) How do concrete and abstract context words co-occur with concrete and abstract words? c) Are our...

Relational categories are more mutable than entity categories.

Across three experiments, we explore differences between relational categories-whose members share common relational patterns-and entity categories, whose members share common intrinsic properties. Specifically, we test the claim that relational concepts are more semantically mutable in context, and therefore less stable in memory, than entity concepts. We compared memory for entity nouns and r...

Context–Supported Road Extraction

Contextual information can facilitate automatic extraction of objects from digital imagery. This paper addresses the use of context for the automatic extraction of roads from aerial imagery. Context is restricted to knowledge about relations between roads and other objects and is hierarchically structured. More specific, context is used to guide road extraction on a global and on a local level....

Study of Scheduling Problems with Machine Availability Constraint

In real world scheduling applications, machines might not be available during certain time periods due to deterministic or stochastic causes. In this article, the machine scheduling with availability constraints for both deterministic and stochastic cases with different environments, constraints and performance measures will be discussed. The existing body of research work in the literature wil...
