There are four typs of noise: Shuffle, Blank, Repetition and Synthetical Noise.
In each folder, the number in the file name represent the level of the noise.
For example,
ce_shuffle_2_hypo.txt: shuffle count is 2
ce_blank_0.5_hypo.txt: blank noise ratio is 5%
ce_rep_5_hypo.txt: repetition noise ratio is 5%
ce_rsbs_5_hypo.txt: synthetical noise ratio is 5% ( corresponds to noise level 1 in the paper)
