Sanitization's slippery slope: the design and study of a text revision assistant

For privacy reasons, sensitive content may be revised before it is released. The revision often consists of redaction, that is, the “blacking out” of sensitive words and phrases. Redaction has the side effect of reducing the utility of the content, often so much that the content is no longer useful.
