==== Domain ====

Mixed: “The text material consists of two sections, the so-called professional prose section (P), with data from textbooks, brochures, newspapers, etc., and a collection of high school students' essays (G).”

==== Size ====

The CoNLL 2006 version contains 197,123 tokens in 11431 sentences, yielding 17.24 tokens per sentence on average (CoNLL 2006 data split: 191,467 tokens / 11042 sentences training, 5656 tokens / 389 sentences test).

==== Inside ====

The morphological analysis in the CoNLL 2006 version does not include lemmas. The part-of-speech tags have been assigned (probably) manually. The tagset is very coarse, there are no morphological features, just the part of speech. Use [[http://quest.ms.mff.cuni.cz/cgi-bin/interset/index.pl?tagset=sv::mamba|DZ Interset]] to inspect the tagset.

==== Parsing ====

Nonprojectivities in Talbanken are not frequent. Only 1928 of the 197,123 tokens in the CoNLL 2006 version are attached nonprojectively (0.98%).

The results of the CoNLL 2006 shared task are [[http://ilk.uvt.nl/conll/results.html|available online]]. They have been published in [[http://aclweb.org/anthology-new/W/W06/W06-2920.pdf|(Buchholz and Marsi, 2006)]]. The evaluation procedure was non-standard because it excluded punctuation tokens. These are the best results for Swedish:
