Abbreviation result from a highly productive type of term variation which substitutes fully expanded terms (e.g., retinoic acid receptor alpha) with shortened term-forms (e.g., RARA). Even though no generic rules or exact patterns have been established for dealing with abbreviation creation, abbreviations often appears in documents without the expanded form explicitly stated. Thus, an abbreviation dictionary is necessary for advanced text-mining tasks to establish associations between abbreviations and their expanded forms.

Acromine is an abbreviation dictionary automatically constructed from the whole MEDLINE as of April, 2009. Acromine identifies abbreviation definitions by assuming a word sequence co-occurring frequently with a parenthetical expression to be a potential expanded form. Applied to the whole MEDLINE (9,635,599 abstracts), the implemented system extracted 68,007 abbreviation candidates and recognized 467,402 expanded forms. The current Acromine achieves 99% precision and 82-95% recall on our evaluation corpus that roughly emulates the whole MEDLINE.
