Reasoning with Mixed Qualitative-Quantitative Representations of Spatial Knowledge
- G. D. Felice
- Computer Science
- 30 June 2013
A hybrid reasoning system is introduced—able to deal with mixed qualitative and quantitative representations of spatial knowledge—combining techniques developed separately for qualitative spatial reasoning and quantitative data analysis.

This paper proposes an extension of existing geographic information systems to support querying-by-sketch, focusing particularly on data management and querying performance, and introduces three different strategies to systematically reduce the information to manage.
Situation awareness in crowdsensing for disease surveillance in crisis situations
The mobile4D smartphone-based disaster reporting and alerting system is extended with a situation awareness data interpretation and integration layer and its application to the problem of tracking cholera outbreaks is demonstrated.

A new qualitative model for visibility relations based on properties of the projective space is proposed and a set of seven ternary relations among convex regions is presented.
A Hybrid Geometric-Qualitative Spatial Reasoning System and Its Application in GIS
We propose a hybrid geometric-qualitative spatial reasoning system that is able to simultaneously deal with input information that is partially given geometrically and partially qualitatively using…
An egocentric semantic reference system for affordances
A theory of egocentric semantic reference systems for human observations of affordances that can be used to semantically account for subjective human observations on the web is suggested.

Reasoning system to derive spatial information out of mixed quantitative-qualitative representations
- G. D. Felice
Spatial data representation and the possibility of making spatial reasoning is essential in the field of Artificial Intelligence. There has been considerable research on spatial representations which…
A Qualitative Perspective on Volunteered Geographic Information
In this paper, we present a novel framework for qualitative spatial information managing, constituting an extension for Geographic Information Systems (GIS), and valuable solutions to several issues…
