IARPA’s HIATUS Program, “Seeks to Develop Novel Human-Useable Systems for Attributing Authorship and Protecting Author Privacy”

From an IARPA (Intelligence Advanced Research Projects Activity) Announcement:

The HIATUS program seeks to develop novel human-useable systems for attributing authorship and protecting author privacy through identification and leveraging of explainable linguistic fingerprints. HIATUS Performers will focus on three task areas (TAs). The program will develop novel methods to generate a stylistic feature space in which each author is represented in stable fashion across diverse text types (TA1). Using this feature space, the program will also create human-interpretable algorithms for authorship attribution (TA2) and author privacy (TA3). Technical approaches must scale to other languages.
