Uncertainty in a situation analysis perspective
Anne-Laure Jousselme, Patrick Maupin, Éloi Bossé · 2003
This paperproposes a discussion on the role of iincerfainty in situation analysis. An overview of the princi- pal typologies of uncertainty foundin the recent literuture is presented. This wide array of uncet-tainty conceptions is a consequence of the intrinsic richness and ambiguity of nat- ural language, but also a consequence of the complexplivs- ical nature of information. Definitions of a liniited number of concepts are proposed in order to better understand the diflerent facets of uncertainty. The benefits sought are: (I) the avoidance of untimely uses of dejniriorls and models of uncertainty. (2) clarifications allowing links with the al- ready well developed logics of knowledge and belief; and (3) guidelines for the selection of the appropriate mathe- matical model to process uncertainty-based information.
