摘要：We present an implemented machine
learning system for the automatic detection
of nonreferential it in spoken dialog.
The system builds on shallow features extracted
from dialog transcripts. Our experiments
indicate a level of performance that
makes the system usable as a preprocessing
filter for a coreference resolution system.
We also report results of an annotation
study dealing with the classification of
it by naive subjects.
