en-US abbrevations

This is a dataset of abbreviations. Contains examples of abbreviations and regular words. There are two subsets:

wiki - more accurate, manually annotated subset. Collected from abbreviations in wiki and words in CMUdict.
kestrel - tokens that are automatically annotated by Google text normalization into PLAIN and LETTERS semiotic classes. Less accurate, but bigger. Files additionally contain frequency of token (how often it appeared) in a second column for possible filtering.
