Abstract
Preparing narrative medical records for use outside of their originating institutions requires that protected health information (PHI) be removed from the records. If researchers intend to use these records for natural language processing, then preparing the medical documents requires two steps: (1) identifying the PHI and (2) replacing the PHI with realistic surrogates. In this chapter we discuss the challenges associated with generating these realistic surrogates and describe the algorithms we used to prepare the 2014 i2b2/UTHealth shared task corpus for distribution and use in a natural language processing task focused on de-identification.

Somewhat confusingly, “re-identification” is also sometimes used to refer to determining a person’s true identity from de-identified data [7], so we avoid that term for the remainder of this chapter.
