Abstract [en]

Timelines allow to represent temporally-rich informa-tion about plans as well as the current execution statusof plans. Recent work has addressed the related issueof inferring timelines representing contextual informa-tion — often useful for informing planning and/or planexecution monitoring processes. The present article ad-dresses the particular issue of inferring context fromgiven models of how observations relate to context,and representing this context on timelines. We strive toabandon assumptions currently made on context recog-nition, namely that hypotheses are either confirmed ordisproved. We propose a technique which allows to ac-cept the inferred context on a timeline with a degree ofpossibility. The approach is based on fuzzy constraintreasoning, and captures two sources of uncertainty: un-certainty in the model that is used to infer context, anduncertainty in the observations. We also formulate theproblem of searching for the most likely timeline as aConstraint Optimization Problem.
