Qualitative Spatial Reasoning in 3D: Spatial Metrics for Topological Connectivity in a Region Connection Calculus
TL;DR: New metrics are presented to bridge the gap required for integration between topological connectivity and size information for spatial reasoning and should be useful for a variety of applications dealing with 3D objects.
An algebra for opengis ® coverages based on topological predicates
Danilo Palomo,Gilberto Câmara +1 more
TL;DR: This work proposes a specification for an algebra for Open GIS coverages which uses a dimension-extended version of Egenhofer and Herring’s 9-intersection predicates to express spatial operations.
Journal ArticleDOI
An Overview of the Research on Topological Relations and Future Issues in GIScience
TL;DR: An overview of the research on topological relations, especially reporting recent breakthroughs after the introduction of the 9-intersection is given, and basic ideas of two relevant inventions are explained: conceptual neighborhood graphs and qualitative spatial calculi.
Dissertation
Spatial description-based approach towards integration of biomedical atlases
TL;DR: Evaluation, particularly in the context of mouse gene expression data, suggests that the spatial description-based solution can provide good spatial precision, and a compromise solution which captures location in biomedical images via spatial descriptions is proposed.
Dissertation
Dealing with Semantic Heterogeneity in Classifications
TL;DR: MinSMatch is described, a semantic matching tool developed evolving S-Match that computes the minimal mapping between two lightweight ontologies, and a formal definition of minimal and, dually, redundant map-pings is provided, evidence of the fact that the minimal mapped always exists and it is unique and a correct and complete algorithm for computing it.

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.
