A Hierarchical Approach to the Line-Line Topological Relations
Zhilin Li,Min Deng +1 more
TL;DR: A hierarchical approach is proposed for the description and determination of basic relations between two lines in IR 2.0, which is an application of the line-line topological relations in traffic planning.
Elaboration d'un moteur de traitement des données spatiales massives vectorielles optimisant l'indexation spatiale
TL;DR: The objective was to find a scalable way of indexing vectorial massive data, ensuring their compatibility with ISO-19125 and its extensions, and making them accessible from GIS, and the result is the Elcano system which provides increased performance compared to current market solutions.

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.

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.
