Measures of contextuality and non-contextuality [PDF]

open access: yesPhilosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2019
We discuss three measures of the degree of contextuality in contextual systems of dichotomous random variables. These measures are developed within the framework of the Contextuality-by-Default (CbD) theory, and apply to inconsistently connected systems (those with ‘disturbance’ allowed).

Probabilistic foundations of contextuality

open access: yesFortschritte Der Physik, 2017
Contextuality is usually defined as absence of a joint distribution for a set of measurements (random variables) with known joint distributions of some of its subsets.

Hypergraph Contextuality

open access: yesEntropy, 2019
Quantum contextuality is a source of quantum computational power and a theoretical delimiter between classical and quantum structures. It has been substantiated by numerous experiments and prompted generation of state independent contextual sets, that is,

Histogram Contextualization

IEEE Transactions on Image Processing, 2012
Histograms have been widely used for feature representation in image and video content analysis. However, due to the orderless nature of the summarization process, histograms generally lack spatial information. This may degrade their discrimination capability in visual classification tasks.

Norm Contextualization

2013
Agents interact with each other regulating by a set of norms which is expressed at different levels of abstraction that capture different contexts and operationalizations. Current normative frameworks deal with norm operationalization, yet few consider the contextual aspects of norms.

Contextual logic of change and contextual proofs

Proceedings of TIME '97: 4th International Workshop on Temporal Representation and Reasoning, 2002
We discuss CLOC, an alternative approach to reasoning about action and change, which is neither based in the Situation Calculus nor in Circumscription. In our approach, inspired by the Possible Worlds Approach, change is modeled as changing the theory that models the world.

Contextual and contextualized knowledge: an application in subway control

International Journal of Human-Computer Studies, 1998
The control of the subway line traffic is a domain where operators must deal with huge quantities of pieces of knowledge more or less implicit in the control itself. When an incident occurs on a subway line, the operator must choose the best strategy applicable for moving from the incidental context to the operational one.
