Dissertation
Modélisation ontologique des connaissances expertes pour l'analyse de comportements à risque : application à la surveillance maritime
TL;DR: In this paper, the authors propose OntoMap, an ontology spatial model for the surveillance maritime domain, which caracterises par des menaces heterogenes, par une zone d'action tres vaste and par un reseau important d'acteurs.

Querying Geographical Data Warehouses with GeoMDQL
Joel da Silva,Ausberto S. Castro Vera,Anjolina Grisi de Oliveira,Robson do Nascimento Fidalgo,Ana Carolina Salgado,Valéria Cesário Times +5 more
TL;DR: This paper presents GeoMDQL, which is a geographical-multidimensional query language, specifically been designed for SOLAP environments, based on well-known standards such as the MDX language and OGC Simple Features Specification for SQL.

Enhancing Spatio-Temporal Identity: States of Existence and Presence
Pierre Hallot,Roland Billen +1 more
TL;DR: A formal analysis of the spatio-temporal states of presence and existence of a geographical object and a combination of these states in order to define a set of life and motion configurations is proposed.

A Model for Representing Topological Relations Between Simple Concave Regions
TL;DR: A more expressive model of topological relations between concave regions is constructed and the Conceptual Neighborhood Graph (CNG) and the Closest Topological Relation Graph (CTRG) of RCC62, which is more expressive than RCC23.
Dissertation
Ontology driven multi-agent systems : an architecture for sensor web applications.
TL;DR: The research proposes an ODMAS framework and an implemented middleware platform, i.e. the Sensor Web Agent Platform (SWAP), which aims to guide and ease the design, development and deployment of dynamic alerting and monitoring applications.

Metaphors We Live By
George Lakoff,Mark Johnson +1 more
TL;DR: Lakoff and Johnson as mentioned in this paper suggest that these basic metaphors not only affect the way we communicate ideas, but actually structure our perceptions and understandings from the beginning, and they offer an intriguing and surprising guide to some of the most common metaphors and what they can tell us about the human mind.
Journal ArticleDOI
Metaphors We Live by
TL;DR: Lakoff and Johnson as discussed by the authors present a very attractive book for linguists to read, which is written in a direct and accessible style; while it introduces and uses a number of new terms, for the most part it is free of jargon.
Journal Article
Maintaining knowledge about temporal intervals
TL;DR: An interval-based temporal logic is introduced, together with a computationally effective reasoning algorithm based on constraint propagation, which is notable in offering a delicate balance between space and time.

The Theory of Parsing, Translation, and Compiling
Alfred V. Aho,Jeffrey D. Ullman +1 more
TL;DR: It is the hope that the algorithms and concepts presented in this book will survive the next generation of computers and programming languages, and that at least some of them will be applicable to fields other than compiler writing.
