The paper offers a new type of approach to the semantic phenomenon of adverbial aspect shift within the framework of finitestate temporal semantics. The heart of the proposal is a supervaluational concept of underspecification, and the idea of treating the meanings of temporal prepositions as dynamic presuppositions. The simple shifting algorithm used in the present approach derives the correct...

This paper1 deals with the definition of a computational semantics for spatial relations between objects in a scene. In particular we examine the effects of the observer's position on the computation of spatial relations, the use of path prepositions, and degrees of applicability for spatial relations. Representational prerequisites and the computational analysis of spatial relations are invest...

Routing and data aggregation are two important techniques for reducing communication cost of wireless sensor networks (WSNs). To minimize communication cost, routing methods can be merged with data aggregation techniques. Compressive sensing (CS) is one of the effective techniques for aggregating network data, which can reduce the cost of communication by reducing the amount of routed data to t...

Abstract We describe two patients who manifested opposite patterns of performance on test batteries that evaluated production, comprehension, and semantic analysis of action verbs on the one hand (e.g. smile, wave, run ) and locative prepositions on the other (e.g. in, on, over ). JP failed all of the verb tests but passed all of the preposition tests, suggesting impaired knowledge of the meani...

The ability to understand and communicate spatial relationships is central to many human-level reasoning tasks. People often describe spatial relationships using prepositions (i.e., in, on, under). Being able to use and interpret spatial prepositions could help create interactive systems for many tasks, including knowledge capture. Here I describe my thesis work modeling the learning and use of...

the relationship between topography, land use, and topsoil moisture storage is investigated for a small catchment with undulating deep loess hilslopes in the south of the netherlands. for a period of 10 months, soil moisture profiles have been measured weekly at 15 locations throughout the catchment. a generalized additive model was employed to find relationships between the various factors inf...
