What types of errors arise when converting consistency parse trees to dependency parse trees?

Question

I wonder what types of errors arise when automatically converting consistency parse trees to dependency parse trees, and how frequent they are.

Answer 1

In Hungarian:

Simkó, Katalin Ilona, et al. "An Empirical Evaluation of Automatic Conversion from Constituency to Dependency in Hungarian." Proceedings of COLING. 2014.

The errors made during [the automatic] conversion were categorized manually in 200 sentences selected randomly from the short business news subcorpus of the Szeged Dependency Treebank, and the most typical ones are listed in Table 1, Column convError.
