clf: classifier

The clf relation is used in noun phrases where a cardinal numeral (1,3), an ordinal numeral (2), or a determiner (4) modifying the head noun is accompanied by a classifier. The classifier is attached to the numeral if a numeral is present, or else to the determiner. Note that ordinal numerals are tagged ADJ and labeled amod in relation to the noun; they are the only words tagged ADJ that can be accompanied by a classifier.

Non-clf functions of Mandarin classifiers

In other constructions involving classifiers, they are annotated with other syntax relations. First, in Mandarin a classifier may also be considered to function as an indefinite determiner when a noun phrase consisting of a bare classifier accompanying a noun is in post-verbal position, as in (4).

1	切	_	VERB	_	_	0	root	_	cut
2	個	_	NOUN	_	_	3	det	_	CL:generic
3	梨子	_	NOUN	_	_	1	obj	_	pear

1	"cut	_	_	_	_	0	_	_	_
2	a	_	_	_	_	0	_	_	_
3	pear"	_	_	_	_	0	_	_	_

Second, if a noun phrase does not have a regular noun, then the classifier is promoted to head of the noun phrase and any numeral or determiner would depend on the classifier, such as in (5) and (6).

1	給	_	VERB	_	_	0	root	_	give
2	我	_	PRON	_	_	1	iobj	_	1SG
3	三	_	NUM	_	_	4	nummod	_	three
4	分鐘	_	NOUN	_	_	1	obj	_	minutes

1	"Give	_	_	_	_	0	_	_	_
2	me	_	_	_	_	0	_	_	_
3	three	_	_	_	_	0	_	_	_
4	minutes."	_	_	_	_	0	_	_	_

1	哪	_	DET	_	_	2	det	_	which
2	位	_	NOUN	_	_	3	nsubj	_	CL:person
3	找	_	VERB	_	_	0	root	_	look-for
4	馬	_	PROPN	_	_	5	compound	_	Ma
5	先生	_	NOUN	_	_	3	obj	_	Mr.

1	"Who	_	_	_	_	0	_	_	_
2	(which	_	_	_	_	0	_	_	_
3	person)	_	_	_	_	0	_	_	_
4	is	_	_	_	_	0	_	_	_
5	looking	_	_	_	_	0	_	_	_
6	for	_	_	_	_	0	_	_	_
7	Mr.	_	_	_	_	0	_	_	_
8	Ma?"	_	_	_	_	0	_	_	_

If there is a genitive 的 de between the classifier and the noun, then the classifier is also treated as a head noun for the numeral, and it is labeled as an nmod dependent of the noun.

1	我	_	PRON	_	_	2	nsubj	_	1SG
2	買	_	VERB	_	_	0	root	_	buy
3	了	_	AUX	_	_	2	aux	_	PERF
4	一	_	NUM	_	_	5	nummod	_	one
5	磅	_	NOUN	_	_	7	nmod	_	CL:pound
6	的	_	PART	_	_	5	case	_	GEN
7	肉	_	NOUN	_	_	2	obj	_	meat

1	"I	_	_	_	_	0	_	_	_
2	bought	_	_	_	_	0	_	_	_
3	a	_	_	_	_	0	_	_	_
4	pound	_	_	_	_	0	_	_	_
5	of	_	_	_	_	0	_	_	_
6	meat."	_	_	_	_	0	_	_	_

Note that classifiers are tagged as NOUN. The feature NounType=Clf is recommended for distinguishing classifiers from regular nouns.
