Uncertain Data Integration with Probabilities
Real world applications that deal with information extraction, such as business intelligence software or sensor data management, must often process data provided with varying degrees of uncertainty. Uncertainty can result from multiple or inconsistent sources, as well as approximate schema mappings. Modeling, managing and integrating uncertain data from multiple sources has been an active area ...
متن کاملA Logic for Uncertain Probabilities
In standard logic, propositions are considered to be either true or false. However, a fundamental aspect of the human condition is that nobody can ever determine with absolute certainty whether a proposition about the world is true or false. In addition, whenever the truth of a proposition is assessed, it is always done by an individual, and it can never be considered to represent a general and...
متن کاملModeling Uncertain Self-Referential Semantics with Infinite-Order Probabilities
The notion of a “second-order probability” (a probability distribution defined over a space of probability distributions), while not exactly commonplace, has become less obscure in recent decades due to the advent of imprecise probability theory as developed by Peter Walley [1] and others [2]. It is straightforward to generalize the notion further to thirdorder probabilities and so forth; and t...
متن کاملApproximate Level-crossing Probabilities for Interactive Visualization of Uncertain Isocontours
A major method for quantitative visualization of a scalar field is depiction of its isocontours. If the scalar field is afflicted with uncertainties, uncertain counterparts to isocontours have to be extracted and depicted. We consider the case where the input data is modeled as a discretized Gaussian field with spatial correlations. For this situation we want to compute level-crossing probabili...
متن کاملSecond order probabilities for uncertain and conflicting evidence
1988; Lauritzen & Spiegelhalter 1988) cannot work as there extsts no probability measure that In this paper the elicitation of probabilities from simultaneously meets all constraints. The ratiohuman experts is considered as a measurement process, which may be disturbed by random ·measurement noise'. Using Bayesian concepts a second order probability distribution is derived reflecting the uncert...
