Spatio-Temporal Ontologies and Attention
This paper presents a new proposal for the design of spatio-temporal ontologies which has its origin in cognitively motivated spatial semantics. It is shown that selective attention not only plays a central role in the characterization of spatial relations but that the representation of attentional aspects also leads to the possibility of defining an ontological upper structure which systematic...
متن کاملGranular Spatio-Temporal Ontologies
We propose an ontological theory that is powerful enough to describe both complex spatio-temporal processes (occurrents) and the enduring entities (continuants) that participate therein. The theory is divided into two major categories of sub-theories: (sub-) theories of type SPAN and (sub-)theories of type SNAP. These theories represent two complementary perspectives on reality and result in di...
متن کاملCognitive Semantics and Spatio-Temporal Ontologies
Cognitive semantics has established close ties between semantics and spatial cognition. Yet, applications of cognitive semantics to the design of spatio-temporal ontologies remain difficult and rare. Ideas such as image schemas, prototypes and radial categories, basic level categories, mental spaces, and conceptual blendings are still largely unexplored in their potential for ontology engineeri...
متن کاملAttention modulates spatio-temporal grouping
Dynamic stimuli are ubiquitous in natural viewing conditions implying that grouping operations need to operate, not only in space, but also jointly in space and time. Moreover, in natural viewing, attention plays an important role in controlling how resources are allocated. We investigated how attention interacts with spatio-temporal perceptual grouping by using a bistable stimulus, called the ...
متن کاملSpatio-temporal analysis of feature-based attention.
The cortical mechanisms of feature-selective attention to color and motion cues were studied in humans using combined electrophysiological, magnetoencephalographic, and hemodynamic (functional magnetic resonance imaging) measures of brain activity. Subjects viewed a display of random dots that periodically either changed color or moved coherently. When attention was directed to the color change...
