Since HP-Obj had produced roughly 17,000 objective sentences used for training, we used the 9,500 new subjective sentences along with 7,500 of the previously identified subjective sentences as our new training set.
the training set that we used during the second bootstrapping cycle contained exactly the same objective sentences as the first cycle, half of the same subjective sentences as the first cycle, and 9,500 brand new subjective sentences.
