"Contextualized VGI" Creation and Management to Cope with Uncertainty and Imprecision
This paper investigates the causes of imprecision of the observations and uncertainty of the authors who create Volunteer Geographic Information (VGI), i.e., georeferenced contents generated by volunteers when participating in some citizen science project. Specifically, various aspects of imprecision and uncertainty of VGI are outlined and, to cope with them, a knowledge-based approach is sugge...

Very significant technical problems had to be solved in those early days: how did one convert the contents of a paper map to digital form (by building an optical scanner from scratch); how did one store the result on magnetic tape (in the form of a linear sequence of records r...
متن کاملMeasuring Uncertainty with Imprecision Indices
The paper is devoted to the investigation of imprecision indices, introduced in [8]. They are used for evaluating uncertainty (namely imprecision), which is contained in information, described by fuzzy (non-additive) measures, in particular, by lower and upper probabilities. We argue that there exist various types of uncertainty, for example, randomness, investigated in probability theory, impr...
