Managing uncertainty in GIS

‘Effective use of . . . information for analysis and decision-making presupposes that the information is correct or reasonably reliable. Information on the quality of data is essential for effective use of GIS: it affects the fitness for use of data for a particular application, the credibility of data representation and interpolation, and the evaluation of decision alternatives.’ (Beard et al ...

Mechanics of Uncertainty: Managing Uncertainty in Mechanics

Uncertainty is ubiquitous in the natural, engineered, and social environments. Devising rationales for explaining it, strategies for its integration into scientific determinism and mitigating its consequences has been an active arena of rational endeavor where many scientific concepts have taken turn at fame and infamy. Far from being a static concept, uncertainty is the complement of knowledge...

Managing Uncertainty in Semantic Tagging

Low interannotator agreement (IAA) is a well-known issue in manual semantic tagging (sense tagging). IAA correlates with the granularity of word senses and they both correlate with the amount of information they give as well as with its reliability. We compare different approaches to semantic tagging in WordNet, FrameNet, PropBank and OntoNotes with a small tagged data sample based on the Corpu...

Managing Uncertainty in Cue Combination

We develop a hierarchical generative model to study cue combination. The model maps a global shape parameter to local cuespecific parameters, which in turn generate an intensity image. Inferring shape from images is achieved by inverting this model. Inference produces a probability distribution at each level; using distributions rather than a single value of underlying variables at each stage p...
