Temporal Action Proposal Generation (TAPG) is a promising but challenging task with wide range of practical applications. Although state-of-the-art methods have made significant progress in TAPG, most ignore the impact temporal scales action and lack exploitation effective boundary contexts. In this paper, we propose simple unified framework named Context Modeling Network (TCMNet) that generate...

The objectives of this paper are to present, describe, and explain the foundations and the functionalities of a temporal knowledge acquisition and modeling solution workflow, which aims at acquiring temporal knowledge from texts in order to populate a constrained object model. We are using several models for temporal data, one of which is generic and employed as a pivot model between a linguist...

In this paper, we present two necessary and sufficient theoretical notions that have to be taken into account for an ITS to dynamically build relevant student models: non-monotonicity, and hypothetical reasoning. These notions issue from the following empirical observations: the student’s cognitive state evolves in time, he/she may have contradictions in mind, and to diagnose his/her knowledge ...

─This paper considers a number of properties of space-time covariance functions and how these relate to the spatialtemporal interactions of the process. The processing of five temporal series is presented to show the difficulties to determine and visualize recognized space of object states. This work is focused on the temporal GIS that will be able to examine human activities under various cons...

A spatiotemporal network is a spatial network (e.g., road network) along with the corresponding time-dependent travel-time for each segment of the network. Design and analysis of policies and plans on spatiotemporal networks (e.g., for path planning with locationbased services) require realistic models that accurately represent the temporal behavior of such networks. In this paper, for the firs...

The objective of upcoming research in the field of geoprocessing is to evolve interoperability standards to develop flexible and scalable controlling and simulation services. In order to overcome the limitations of proprietary solutions, efforts have been made to support interoperability among simulation models and geo information systems (GIS). Existing standards in the domain of spatial infor...

The Unified Modeling Language (UML) has received wide acceptance as a standard language in the field of software specification by means of different diagram types. In a recent version of UML, the textual Object Constraint Language (OCL) was introduced to support specification of constraints for UML models. But OCL currently does not provide sufficient means to specify constraints over the dynam...

The textual Object Constraint Language (OCL) is an official part of the Unified Modeling Language (UML). OCL is primarily used to formulate restrictions over UML models, in particular, invariants and operation preand postconditions in the context of class diagrams. However, OCL is missing means to specify constraints over the dynamic behavior of a UML model. We have therefore developed a tempor...

A data modeling perspective on computer support for collaborative writing is given. In particular, the problem is identified as a temporal database application. The solution proposed is based upon a design system architecture the repository of which uses the GENREG historical data model. GENREG uses event graphs to provide a group memory. Nodes represent the design objects (documents, reference...
