| The only corpus covered so far is the Sinica Treebank, converted to the CoNLL format. The tag set lacks comprehensive documentation (almost zero supplied with CoNLL data, and only a little found in the web). The tags do not encode any morphological features. Instead, there is a comprehensive (but undocumented) hierarchy of word classes and subclasses. Most of the information encoded in the tags cannot be mapped to Interset. | The only corpus covered so far is the Sinica Treebank, converted to the CoNLL format.

| + | ==== CoNLL (derived from PDT) ==== | ||
| + | |||
| + | The CoNLL 2006 and 2007 Czech treebanks are data from PDT converted to the CoNLL format. The PDT morphological tags have been decomposed into coarse-grained part of speech, detailed part of speech, and a set of feature values. There should be a one-to-one mapping between the original PDT and the CoNLL tagsets, however, the driver cannot be a simple envelope around the driver of the original tagset (as is the case for e.g. Penn Treebank tags) because of the features. | ||

| + | Update: the mapping to the original PDT tags is not one-to-one. Some information, | ||
