An Application for Data Using Dear Ma'am, My research is mainly about free-text clinical notes structuring, so I need the i2b2 data set for experiment. Followed the request of https://www.i2b2.org, the "DATA USE AND CONFIDENTIALITY AGREEMENT for Academic Organizations" has been filled and signed, please check the attachment for details. Please consider to distribute me a copy of i2b2 data set. Thanks for your time, and I am very appreciate of the efforts Center for BioMedical Informatics of Harvard Medical School made for impelling the development of clinical data processing. Have a good day! I'd like to phrase more polite and humble, thanks for any help.
