Parsing
Nonprojectivities in BTB are rare. Only 747 of the 196,151 tokens in the CoNLL 2006 version are attached nonprojectively (0.38%).
The results of the CoNLL 2006 shared task are available online. They have been published in (Buchholz and Marsi, 2006). The evaluation procedure was non-standard because it excluded punctuation tokens. These are the best results for Bulgarian:
| Parser (Authors) | LAS | UAS |
|---|---|---|
| MST (McDonald et al.) | 87.57 | 92.04 |
| Malt (Nivre et al.) | 87.41 | 91.72 |
| Nara (Yuchang Cheng) | 86.34 | 91.30 |
