Each folder is dedicated to one group of verbs and contains seveal inner folders, one for each verb. Each inner folder contains three files. For example:
filter_start.py
results_start.tsv
sample_start.tsv
The .py file contains the filters for this particular verb (in this case, "start"); the "results" file contains all the phrases with this verb downloaded from wikisearch; and the "sample" file contains a random sample of 100 phrases that result from application of the filters to the "results" file.
