Effective Implementation of Spatial Topological Operations Based on Anticlockwise Triangle
Peiquan Jin,Jie Zhao +1 more
TL;DR: This paper first divides the vector- based GIS data into a set of non-intersected anticlockwise triangles, and then implements spatial topological operations for common GISData through the sets of anticlock wise triangles.

On Spatial Relations for Non-small Cells Lungs Cancer Interpretation
TL;DR: An algorithm for defining non-small cells lungs cancer stages in lungs images interpretation using topological spatial relations is put forth and an application case study in event motion predictions for lung cancer staging scoring tumor, nodes and metastasis with combined topological and directional relations is shown.

A modeling method of 3D spatial relationship of city construction based on part-whole
TL;DR: The description level and the geometry definition of city construction according to the geometry characteristics of entities in space is presented and a framework for describing three-dimensional spatial relationship of cityConstruction based on the ontology is proposed.

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.

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.
