Measuring Relations Between Concepts In Conceptual Spaces [article]

Lucas Bechberger, Kai-Uwe Kühnberger
2017 arXiv   pre-print
This considerably increases the representational power of our formalization by introducing measurable ways of describing relations between concepts.  ...  The highly influential framework of conceptual spaces provides a geometric way of representing knowledge.  ...  Substitute x = e t and s = −t, then apply the definition of the Γ function.

F-perceptory: an approach for handling fuzziness of spatiotemporal data in geographical databases

Asma Zoghlami, Cyril De Runz, Herman Akdag
2016 International Journal of Spatial Temporal and Multimedia Information Systems  
In this paper, we propose an approach for modelling imprecise data in object and relational databases based on the representation of data using connected and normalised fuzzy sets stored via α-cuts.  ...  All these previous fuzzy conceptual modelling methods are not adapted to fuzzy spatiotemporal data.  ...  Relational database view The possibilistic object representation is a particular case of the fuzzy object representation.  ...

Generating CAD Models from Sketches [chapter]

Sabine Roth-Koch
2002 From Geometric Modeling to Shape Modeling  
The ultimate goal of the application described in this paper is the conversion of two-dimensional sketches into three-dimensional CAD curves and surfaces.  ...  The conceptual designer can develop it into the final concept and into the three-dimensional CAD elements.  ...  The manually prepared initial models (shape models) therefore allow the only truly three-dimensional assessment of the outline and the laying down of the conceptual statement in its entirety.  ...

Level 2/3 Fusion in Conceptual Spaces

John Rickard
2006 2006 9th International Conference on Information Fusion  
This paper presents a novel approach to data fusion knowledge representation using conceptual spaces.  ...  The relative similarity of observations to concepts can then be calculated using the fuzzy subsethood measure.  ...  In the conceptual spaces familiar to humans, some domains are innate and apparently hard-wired in our sensory apparatus, e.g., color, aural pitch and ordinary three-dimensional space.  ...

Proposal of a Document Cluster Representation based on Fuzzy Deformable Prototypes

Francisco P. Romero, José A. Olivas, Pablo J. Garcés
2005 European Society for Fuzzy Logic and Technology  
Therefore, we apply Fuzzy Deformable Prototypes for knowledge representation. Its use allows an easy process to deal with the incoming documents and an efficient update of the structure.  ...  We use fuzzy logic technologies and a KDD based process for automatic classification of large repositories of documents in a fuzzy and hierarchical organization.  ...  Conceptual Representation To get a logical representation is essential to be able to work with the documents in an abstract way.  ...
