# RAW_TRAIN is the input of AutoPhrase, where each line is a single document.
RAW_TRAIN=${RAW_TRAIN:- data/DBLP.txt}
# When FIRST_RUN is set to 1, AutoPhrase will run all preprocessing. 
# Otherwise, AutoPhrase directly starts from the current preprocessed data in the tmp/ folder.
FIRST_RUN=${FIRST_RUN:- 1}
# When ENABLE_POS_TAGGING is set to 1, AutoPhrase will utilize the POS tagging in the phrase mining. 
# Otherwise, a simple length penalty mode as the same as SegPhrase will be used.

# A hard threshold of raw frequency is specified for frequent phrase mining, which will generate a candidate set.

# You can also specify how many threads can be used for AutoPhrase
