## Introduction

The Potsdam Commentary Corpus or PCC was assembled by Dr. Manfred Stede and his colleagues at the Department of Linguistics, University of Potsdam. The PCC contains 176 German newspaper commentaries, which are annotated with syntax trees and three layers of discourse-level information: nominal coreference, connectives and their arguments (similar to the PDTB), and trees reflecting discourse structure according to Rhetorical Structure Theory (Mann and Thompson, 1988).

In the RST framework (Mann and Thompson, 1988), a text's discourse structure can be represented as a tree in four aspects: 

  1. the leaves correspond to text fragments called elementary discourse units (the mininal discourse units); 
  2. the internal nodes of the tree correspond to contiguous text spans; 
  3. each node is characterized by its nuclearity, or essential unit of information; and 
  4. each node is also characterized by a rhetorical relation between two or more non-overlapping, adjacent text spans.

## DISRPT 2019 shared task information

For the DISRPT 2019 shared task on elementary discourse unitsegmentation, the data was divided into train, test and dev partitions, comprising 142, 17 and 17 documents, respectively.

Syntactic (automatic) dependency parses are made available using UDpipe with the 2.3 model for German.
