[Corpora-List] ?spam? Time costs between manual pos tagging of English and Chinese corpus

[Oliver Mason]

This of course would support the argument that there are no word
classes, or at least that they are not useful for Chinese. Years ago
John Sinclair mentioned the notion of a 'norb', a word with an
unresolved noun/verb ambiguity, while we were working on a
'context-free' tagger. Maybe you need a tag in your case that can
cover both 'reform' as the nominal concept and 'to reform' as the
verbalisation of that concept. Something along the lines of "process
word", which could be translated into English either as a verb or a
noun.
