Identifying Abbreviations in Biomedical Text
Idea
Abbreviations, synonyms and acronyms are heavily used in biomedical literature, for describing names of genes, diseases, biological processes and more. Recognizing short or alternative name forms and mapping them to the full (long) form is important to the full understanding of scientific text. In the context of information extraction tasks, recognizing abbreviated forms can lead to a great increase in recall. This task is especially challenging since abbreviations are often reused, for example, names of genes and systems are shared across species, and since researchers often do not adhere to standard naming conventions. In this project we wish to provide a model for linking an abbreviated or short form biomedical terms to full terms as well as recognize abbreviations that may relate to more than a single entity.
Challenges
- Recognize candidate <short-form, long-form> pairs from text
- Extract possible long-form versions for each of the abbreviated short-forms
- Suggest the most probable long-form of an abbreviation based on the content of a given text document (the base assumption will be that in a single document an abbreviation may only refer to a single long-form - even if it may have many more possible long-forms in other, even closely related, context).

Dataset
MEDSTRACT is a collection of automatically extracted acronym pairs from MEDLINE databases. The data includes:
- Gold Standard Data: Sentences including abbreviations.
- Gold Standard Results: Pairs of <abbreviation, full form name> that appear in the data.
- The data does not seem completely coherent and may need to be "cleaned".
