Towards geologically reasonable lithological classification from integrated geophysical inverse modelling: methodology and application case
TL;DR: In this paper, a methodology for the recovery of lithologies from geological and geophysical modelling results and applying it to field data is proposed, which relies on classification using self-organizing maps (SOM) paired with geoscientific consistency checks and uncertainty analysis.

A Framework for the Description of Spatiotemporal Relationships
Peiquan Jin,Lihua Yue +1 more
TL;DR: This paper first proposes a systematic classification on spatiotemporal relationships, and then a framework for the representation of different types of spatiotmporal relationships is presented, which is further divided into two types: time-varying topology and history topology.

Les états spatiotemporels d’existence et de présence - Vers une définition des relations entre objets absents ou inexistants
TL;DR: Ce travail presente une nouvelle approche visant a caracteriser les relations spatiotemporelles qui existent entre objets geographiques qui sont absents ou inexistants au moment of l’analyse.

Interconnexion et visualisation de ressources géoréférencées du Web de données à l’aide d’un référentiel topographique de support
TL;DR: Les applications de visualisation cartographique des ressources georeferencees du Web de donnees ne fournissent pas une visualisation lisible a toutes les echelles, nous proposons un vocabulaire pour formaliser les connaissances sur les caracteristiques de chaque geometrie dans un jeu de donnes.

A computational model for direction relations between spatial objects in GIS
TL;DR: A novel model named Radial model is proposed to obtain both quantitative and qualitative direction relations based on the principle of the ray transmitting as a straight line to calculate direction relations on the vector and raster spatial data model in GIS.

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.
