    Sam Cottrell



    This paper explores what is understood by common uncertainty terms (e.g., circa, approximately, around) and how the associated date information affects the perceived range of a given date. This is accomplished through a study incorporating an interactive timeline. Participants are presented with a date and associated uncertainty term, and instructed to mark the possible and probable extents. The results from the study have been used to produce guidelines on the capture of dates, in order to include textual uncertainty and represent them visually.
