For example, Figure 7 demonstrates how we generate the training instances (right) from a gold DT with four EDUs (left).
in RST-DT, by our count, 7, 321 out of 7, 673 sentences in the training set, 951 out of 991 sentences in the test set, and 1, 114 out of 1, 208 sentences in the doubly-annotated set have a well-formed DT.
