Wayfinding in a natural setting is one of the many complex processes human beings face when acting in the environment. Despite recent developments and applications of wayfinding in urban environments, little research has been oriented and applied to natural environments. The research presented in this article introduces an ontological and language-based(More)
Over the past few years, several alternative approaches have been suggested to represent the spatial knowledge that emerges from natural environments. This paper introduces a rule-based approach whose objective is to generate a spatial semantic network derived from several humans reporting a navigation process in a natural environment. Verbal descriptions(More)
concise and intensional periodic time expressions (Carnap 1947) instead of their extensional counterparts. This point gains in importance with the expansion of mobile and ubiquitous systems, which leads to an increased volume of such space and time located queries. Of course, information about local time and space can directly be captured from the mobile(More)

In this paper, we present a platform we have designed and built in order to generate data and scenario traces that can serve as inputs and references when evaluating our algorithms for detecting cyber security intrusions. Our context is related to civilian and military ships and our research is performed within a strong partnership with industry and(More)
This paper introduces a modelling approach oriented to the representation of urban activities which takes into account several interacting spatio-temporal constraints. An activity is modeled as a constraint-based path with different transportation modalities and points of interest identified in a given urban system. The objective of this spatio-temporal(More)
