The perceptual coherence of auditory and visual information is achieved by integrative brain processes. Specialized single neurons with spatial and temporal interactions of auditory and visual stimuli have been demonstrated by several neurophysiological studies. The present, psychophysical, study investigates possible perceptual correlates of these neuronal features. Subjects had to indicate th...

* Work partially supported by the TMR CHOROCHRONOS European project. Abstract When authoring multimedia scenarios, and in particular scenarios with user interaction, where the sequence and time of occurrence of interactions is not predefined, it is difficult to guarantee the consistency of the resulting scenarios. As a consequence, the execution of the scenario may result in unexpected behavior...

Temporal information retrieval received a lot of attention during the last years and it is, in the meantime, widely accepted in the IR community that temporal information needs are important to tackle. A particular type of temporal queries are those with explicit temporal constraints, which make almost 15% of today’s Web search queries. Although several approaches to allow textual search combin...

This paper presents a model of the temporal structure of repeating events. This model allows for the representation of quantitative temporal constraints for repeating events, viz., those dealing with their part-whole structure. The temporal structure of repeating events is viewed as being composed of ve properties: number, sub-interval duration, gap duration, period and extent. A set of constra...

The paper presents a novel compilation scheme for temporal integrity constraints and deductive rules expressed in an interval-based rst-order temporal logic. Compilation builds a dependence graph with simpliied forms of the constraints and rules. This permits the compile-time simpliication of the formulae that have to be veriied at run-time, as well as the precomputation of potential implicit u...

The decision to take vaccinations and other protective interventions for avoiding an infection is a natural game-theoretic setting. Most of the work on vaccination games has focused on decisions at the start of an epidemic. However, a lot of people defer their vaccination decisions, in practice. For example, in the case of the seasonal flu, vaccination rates gradually increase, as the epidemic ...

This paper describes a model for temporal reasoning that handles both quantitative and qualitative information affected by vagueness and uncertainty. Starting from two existing models, namely the Meiri’s system [9] and IA fuz [2, 3], the proposed approach generalizes the first to a fuzzy framework and extends the second in order to handle qualitative constraints. The system uses the Fuzzy Const...

This paper investigates how linguistic expressions of time, in particular temporal adverbs and verb tense morphemes, are used to establish temporal reference in the brain. First, a semantic analysis of tense and temporal adverbs is outlined. It is proposed that computing temporal reference amounts to solving a constraint satisfaction problem. Further, the results of an ERP study are presented w...

This study presents the spatio-temporal constraint relationships of moving objects by employing Petri Net technology. The spatial constraints of moving objects are first presented in this study based on the V4I [1] theory, then the temporal constraints for moving objects are presented by applying this theory to temporal aspect. With the proposing of Moving Object Petri Net (MOPN) and Spatial Co...
