Dissertation
Putting the past in place : a conceptual data model for a 4D archaeological GIS
TL;DR: In this article, the authors propose a solution to solve the problem of homonymity in homonym identification, i.e., homonym-of-individuals-with-groups.

SNAL: Spatial Network Algebra for Modeling Spatial Networks in Database Systems
TL;DR: A general-purpose abstract model is proposed as a specification for a later implementation of spatial networks in different environments such as spatial database systems and GIS.
Dissertation
Testing native speakers of German and Portuguese on the understanding of topological operators-line-region relations in gvSIG
TL;DR: In the present usability study, natural language terms that describe topological operators in gvSIG software were tested among native speakers of German and Portuguese to find out if users’ understand the operators according to the system designer.
Maintaining Relational Consistency in a Graph-Based Place Database
TL;DR: The study provides a first step into using a graph database to storing and querying qualitative spatial data from NL place descriptions, and provides some insights for the system implementation.

Book
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.
