Book ChapterDOI
Regional Algebra for Spatial Data Management
TL;DR: An extension to the relational model is defined for the management of spatial data that adopts a radically new methodology for the formalization of three spatial data types, point, line and surface, based on a definition for spatial quanta.
Journal ArticleDOI
On Weak and Strong Forms of Fuzzy Soft Open Sets
TL;DR: Fuzzy soft pre-open (closed) sets are defined and discussed, and some properties of fuzzy soft neighborhood system, fuzzy soft basic neighborhood and fuzzysoft neighborhood (nbd) base at fuzzy soft point are studied.
Book ChapterDOI
TerraHS: Integration of Functional Programming and Spatial Databases for GIS Application Development
TL;DR: This paper argues that many of theoretical problems in GIScience can be expressed as algebraic theories, and developing a GIS in a functional language is not feasible, since many parts needed for aGIS are already avaliable in imperative languages such as C++ and Java.
Proceedings ArticleDOI
Topological matrices for topological relations between fuzzy regions
TL;DR: This paper discusses different definitions in fuzzy boundary and their differences and relations, and one of the definitions is selected as the fuzzy boundary for GIS.
Geographical Domain and Geographical Information Systems
TL;DR: In this article, a distinction is made between map and geomap based on the notion of locusobject, and the contribution of the morpho-genetic representation to the comprehension of the cycle: reality, representation, model, reality.

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.
