Size

The CoNLL 2006 version contains 35140 tokens in 1936 sentences, yielding 18.15 tokens per sentence on average (CoNLL 2006 data split: 28750 tokens / 1534 sentences training, 6390 tokens / 402 sentences test).

Inside

The original morphosyntactic tags have been converted to fit into the three columns (CPOS, POS and FEAT) of the CoNLL format. There should be a 1-1 mapping between the BTB positional tags and the CoNLL 2006 annotation. Use DZ Interset to inspect the CoNLL tagset.

The morphological analysis includes lemmas. The morphosyntactic tags have been assigned (probably) manually.

Parsing

Nonprojectivities in SDT are not frequent. Only 675 of the 35140 tokens in the CoNLL 2006 version are attached nonprojectively (1.92%).

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 Slovene:
