 All the resources (such as: annotation file, parsed tweet file, the bing liu sentiment lexicons...) should be placed in a folder named `data` inside this project.
 This is because it is the default value in the parser. It is annoying to add all those options!
 
+In order to reproduce the results run:
+
+    python classify_tweets.py --tweets-file ./data/dataset/tweet_for_dp.txt.predict --annotations ./data/dataset/TweetsAnnotation.txt -c lr_h
+    --rm-url --stem --bingliusent --depsent --negwords --bigramsent --unigramsent --subjscore --sentnet --argscores --scale --class-weights --optim-single
