Detecting spatio-temporal topological relationships between boundary lines of parcel
TL;DR: Taking the cadastral data of two different years at the same area as example, experimental program is developed to query change types of boundary lines by their spatio-temporal topological relationships according to rules above.
Proceedings ArticleDOI
Formal Qualitative Spatial Augmentation of the Simple Feature Access Model
Shirly Stephen,Torsten Hahmann +1 more
TL;DR: This work formalizes the semantics of SFA's geometric features and mereotopological relations by defining or restricting them in terms of the spatial entity types and relations provided by CODIB, a first-order logical theory from an existing logical formalization of multidimensional qualitative space.
Book ChapterDOI
Description of combined spatial relations between broad boundary regions based on rough set
TL;DR: The rough set theory is introduced into describing combined spatial relations between broad boundary regions and the combination of the topological and direction relations betweenbroad boundary regions is used to describe Combined spatial relations.
Journal ArticleDOI
A Generalized 9-Intersection Model for Topological Relations between Regions with Holes
TL;DR: A generalized 9-intersection model is proposed, which can completely describe detailed topological relations between regions with holes and detailed topology relations between objects of different complexities with the same major categories of topological Relations.
Book ChapterDOI
Automatic Extraction of Complex Objects from Land Cover Maps
TL;DR: An approach to give a semantic characterization to complex objects and a functional strategy to identify complex objects in an image and to build a visual representation compatible with the scale and resolution of the original map is developed.

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.
