Known unknowns: representing uncertainty in historical time
- Historic time is inherently uncertain, with missing, disputed, doubtful or ill-defined dates for objects and events. Yet digital timeline visualisations tend to represent it as exact and of undisputed confidence. This is partly due to a lack of awareness, partly due to a lack of support for ambiguities in digital data types and modes of representation. We outline some of the issues around uncertainty in timeline visualisation and ways of addressing them.
