 Morphological annotation includes lemmas. Morphosyntactic tags were probably disambiguated manually.

+There are special derivational nodes. Derived words have been split into several tokens (see also the sample below). Typical pattern (maybe the only pattern but I have not confirmed that) is as follows: There are two nodes connected with a dependency link. The head node corresponds to the surface word. It has the word form, part of speech and morphological features but it has no lemma (lemma is '_'). The surface word is a result of a derivational morphological process. It has been derived from another word, often a different part of speech (e.g. a noun was derived from a verb). The dependent node represents the source of the derivation. It has no word form but it has a lemma. Its part-of-speech tag describes the source word and thus it can differ from the part-of-speech tag of the head node. The FEAT column says just 'Pos'. The dependent node need not be a leave. Other nodes may depend on it, instead of depending on the parent node. If we have a noun derived from a verb, i.e. we have a verbal node depending on the nominal node, and there is a dependent filling a verbal valency slot of the derived noun, we can expect the dependent to be attached to the verbal node.
+Occasionally there are derivational chains longer than two nodes. An example is in the sentence No. 82 of the test data:
+lemma azal / Verb -> _ / Verb / Caus -> _ / Verb / Pass|Pos -> azaltılması / Noun / NInf / A3sg|P3sg|Nom
+According to Google Translate, //azal// means “to decrease” and //azaltılması// means “reduced”. TRmorph gives the following four analyses:
+<code>
+analyze> azaltılması
+azal<v><caus><pass><vn_ma><p3s>
+azal<v><caus><pass><vn_ma><p3s><3s>
+azal<v><caus><pass><vn_ma><p3s><3p>
+azal<v><caus><pass><cv_ma><p3s>
+</code>

-SzTB is a mildly nonprojective treebank. 4032 of the 139,143 tokens of the CoNLL 2007 version are attached nonprojectively (2.9%).
+Nonprojectivity rate in METU-Sabanci is relatively high. 3716 of the 69695 tokens of the CoNLL 2007 version are attached nonprojectively (5.33%).
-The results of the CoNLL 2007 shared task are [[http://nextens.uvt.nl/depparse-wiki/AllScores|available online]]. They have been published in [[http://aclweb.org/anthology-new/D/D07/D07-1096.pdf|(Nivre et al., 2007)]]. The evaluation procedure was changed to include punctuation tokens. These are the best results for Hungarian:
