Abstract
The talk describes several techniques used to visualize among other aspects the productivity of rule sets in deriving non-standard spellings. The treemap or similar visualizations help find typical replacement sequences depending on the localization of the spellings and their epoch. The study conducted proves that treemaps ease the understanding of rule hierarchies, the detection of productive and non productive rules and the evaluation of a rule’s importance. They also provide better search performance. An interactive visualization over a map is showing isoglosses running between different regions of Germany and clusters text samples of different epochs and their writings. Furthermore, allograph variants are displayed using adequate data types.
