The morphological annotation includes lemmas. The syntactic annotation is mostly identical to that of the Corpus Gesproken Nederlands (CGNSpoken Dutch Corpusas described in the file ''syn_prot.pdf'' (Dutch only). An attempt to describe number of differences between the CGN and Alpino annotation practice is given in the file ''diff.pdf'' (which is heavily out of date, but the number of differences has been reduced)Conversion issueshead selection, multi-word units, discourse units.
  
-The morphological analysis in the CoNLL 2006 version does not include lemmas (the original DTAG version does contain them). The morphosyntactic tags have been assigned (probably) manually. +Multi-word expressions have been concatenated into one token, using underscore as the joining character (e.g. "Economische_en_Monetaire_Unie"). They have special part-of-speech tags ''MWU'', their subparts of speech and features may describe the individual parts of the unit. E.g. "aan_het" has CPOS ''MWU'', (sub)POS ''Prep_Art'' and features ''voor_bep|onzijd|neut''.
- +
-Some multi-word expressions have been collapsed into one token, using underscore as the joining character. This includes adverbially used prepositional phrases (e.g. i_lørdags = on Saturdaysbut not named entities.+
