Fuzzy sets in database and information systems: Status and opportunities
TL;DR: Fuzzy set approaches have been applied in the database and information retrieval areas for nearly 30 years and aspects of these areas that seem to afford the greatest potential for further development are considered.

Jan Caha,Veronika Nevtípilová,Jiří Dvorský +2 more
- 11 Jun 2014
TL;DR: The study presents utilization of Possibility theory for modelling constraints and preferences for spatial data and the main aim is focused on providing more information to the decision maker that will allow him to select the most suitable alternative.
Representation of and reasoning with vagueness in spatial information : a system for handling vague objects
Arta Dilo
TL;DR: This research presents a system for handling vague objects in spatial information, demonstrated through real-world applications, including environmental monitoring and land cover change analysis, to facilitate reasoning with uncertainty and vagueness in spatial data.
A system of types and operators for handling vague spatial objects
TL;DR: In this paper, the authors present a method for representing and analysing vague spatial phenomena, which requires vague objects and operators, whereas current GIS and spatial databases can only handle c...
On Place-Based GIS
刘瑜,谢昆青,方裕,潘懋,邬伦 +4 more
TL;DR: This paper discusses place-based GIS (PB-GIS), which leverages spatial cognition to support spatial decision-making, and proposes a 3-layered software architecture, comparing its applications and advantages with conventional coordinate-based GIS (CB-GIS).

PRUF—a meaning representation language for natural languages
TL;DR: In addition to serving as a foundation for approximate reasoning, PRUF may be employed as a language for the representation of imprecise knowledge and as a means of precisiation of fuzzy propositions expressed in a natural language.

Note on fuzzy languages
E. T. Lee,Lotfi A. Zadeh +1 more
TL;DR: An explicit expression for the membership function of the language L(G) generated by a fuzzy grammar G is given, and it is shown that any context-sensitive fuzzy grammar is recursive.

Some approaches for relational databases flexible querying
Patrick Bosc,Olivier Pivert +1 more
TL;DR: It is shown that the approach based on fuzzy sets is powerful enough to answer a wide range of imprecise queries in an appropriate way and to support the expression of the capabilities available in the other classes of solutions.

Towards a natural language user interface: an approach of fuzzy query
TL;DR: A fuzzy query approach is presented which is aimed at introducing more natural language expressions into GIS user interfaces and enables modification-type, composition-type and quantification-type fuzzy formulae to be used for data retrieval.
