+### [Dataset Summary](#dataset-summary)
+
+The goal of the style change detection task is to identify text positions within a given multi-author document at which the author switches. Detecting these positions is a crucial part of the authorship identification process, and for multi-author document analysis in general.
+
+Access to the dataset needs to be requested from zenodo.
