A classical measure is essentially a set function satisfying nonnegativity and countable
additivity axioms. However, the additivity axiom of classical measure theory has been …

Some information and knowledge are usually represented by human language like “about
100km”,“approximately 39° C”,“roughly 80kg”,“low speed”,“middle age”, and “big size”. How …

In this chapter we argue, both from a theoretical (Situational Action Theory) and
methodological (homogeneity of environmental conditions) point of view, that …

Patterns in crime vary quite substantially at different scales of aggregation, in part because
data tend to be organized around standardized, artificially defined units of measurement …

Although the region connection calculus (RCC) offers an appealing framework for modelling
topological relations, its application in real-world scenarios is hampered when spatial …

The scientific literature on fuzzy numbers and arithmetic calculations is rich in several
approaches to define fuzzy operations having many desired properties that are not always …

We propose a fuzzy qualitative (FQ) version of robot kinematics with the goal of bridging the
gap between symbolic or qualitative functions and numerical sensing and control tasks for …

This paper proposes a fuzzy qualitative approach to vision-based human motion analysis
with an emphasis on human motion recognition. It achieves feasible computational cost for …

Broad boundary is generally used to replace one‐dimensional boundary for spatial objects
with vague shape. For regions with broad boundary, this concept should respect both …

Qualitative spatial information plays a key role in many applications. While it is well-
recognized that all but a few of these applications deal with spatial information that is …
