Christina Lioma and Birger Larsen and Hinrich Schütze and Peter Ingwersen
2017 arXiv   pre-print
Specifically, we apply Subjective Logic to model different representations of information needs as beliefs marked by degrees of uncertainty.  ...  The identification and representation of such contexts has been the object of the principle of Polyrepresentation, a theoretical framework for reasoning about different representations arising from interactive  ...  One of the earliest applications of formal logic to IR was Van Rijsbergen's Logical Uncertainty Principle [56] .  ...

The Uncertainty Relation for Quantum Propositions

Paola Zizzi
2012 International Journal of Theoretical Physics  
Logical propositions with the fuzzy modality "Probably" are shown to obey an uncertainty principle very similar to that of Quantum Optics.  ...  In the logical case, the uncertainty relation is about the assertion degree, which plays the role of the phase, and the total number of atomic propositions, which plays the role of the number of modes.  ...  We argue that logical coherence should have both interpretations, respectively at the level of QOL and at the level of QML.  ...

Biological Information Processing Requires Quantum Logic

Tetsu Oi
1988 Zeitschrift für Naturforschung C - A Journal of Biosciences  
This principle corresponds to the microscopic uncertainty principle that holds in quantum physics.  ...  In this system, the macroscopic uncertainty principle holds between observation time Δt and phase space volume ΔΩ determined by this observation.  ...  of the time operator.  ...

Principles of Modern Physics

Robert B. Leighton, W. H. Furry
1960 American Journal of Physics  
The Principle of Uncertainty. This principle was enunciated by Werner Heisenberg at the onset of the quantum theory.  ...  The electron is then not a thing-in-itself; its nature is dependent, in part, on the way in which the macro-observer looks at it! This is an epistemological view of positivism.  ...

Games in Dynamic-Epistemic Logic

Johan van Benthem
2001 Bulletin of Economic Research  
At the 'outcome level', we present suitable notions of game equivalence, plus some simple representation results. 2 Here is a typical modal assertion which is true at the root: [c d]p each of the actions  ...  Consider again the above game, but now with an uncertainty for player E about which move was played by A initially. (Perhaps, A put his move in an envelope.)  ...  look at the more global outcome level, looking for analogues of Sections 2.3, 2.4.  ...

Uncertainty—Its Ontological Status and Relation to Safety [chapter]

Ove Njå, Øivind Solberg, Geir Sverre Braut
2017 SpringerBriefs in Applied Sciences and Technology  
Aiming these questions at uncertainty reveals that interpreting uncertainty as existing in any ontological sense is difficult to defend.  ...  Epistemological understandings of uncertainty encompass, in principle, the whole rationality spectrum from relativism to positivism, thus not excluding any form of analyses or understanding of uncertainty  ...  In relation to the ALARP principle we can see uncertainty in at least two aspects.  ...

Visual representation of rational belief revision: another look at the Sleeping Beauty problem

David R. Mandel

The choice uncertainty principle

Peter J. Denning
2007 Communications of the ACM  
It might be asked whether there is a connection between the choice uncertainty principle and the Heisenberg Uncertainty Principle (HUP) of quantum physics.  ...  CHOICE UNCERTAINTY AS A GREAT PRINCIPLE The choice uncertainty principle is not about how a system reacts to an observer, but how an observer reacts to a system.  ...

Diversity of Logical Agents in Games

Johan van Benthem, Fenrong Liu
2004 Philosophia Scientiæ  
Valid laws of reasoning about agents and plans Universally valid principles of our language include the minimal modal or dynamic logic, plus the epistemic logic matching the uncertainty relations -in our  ...  For, after move a is played, A has learnt nothing that would now enlighten him, so there should be an uncertainty line at the mid-level as well. But in another sense, A has learnt something!  ...

But in another domain, that of the philosophical founding of physics, serious efforts have been made to find a philosophical deduction of certain metaphysical principles, e.g. the axiom of reciprocity,  ...  As we are looking for methods, and as, on the other hand, logic plays a part in the trains of thought to be described, the short digression here into this non-mathematical field may be justified.  ...

The philosophical significance of Cox's theorem

Mark Colyvan
2004 International Journal of Approximate Reasoning  
Of particular interest is the thesis that the only coherent means of representing uncertainty is via the probability calculus.  ...  In this paper I examine the logical assumptions of Cox's theorem and I show how these impinge on the philosophical conclusions thought to be supported by the theorem.  ...  A version of this paper was presented at the Australasian Association of Philosophy Conference at the University of Queensland in July 2000.  ...
