About proprocessing code

the proprocessing code is written in Java. The downloaded datasets were in form of SQLite, that is why we initially statblish connection with database [com.yelp.database]. A customize engine [com.engine.*] is develop to extract features from text data. The code of overall number of feature extraction can be found in [com.yelp.rest.FeatureExtractor].
