CHARTextract is a rule-based information extraction tool with the ability to quickly and easily refine rules on-the-fly.

By combining physician knowledge and keyword-based pattern matching, we can extract patient attributes (e.g., diagnosis, country of birth, procedures, etc.) from free-form text notes.
