I remember hearing about a (proprietary, SaaS) system that could track people's activity on the Internet by analyzing text and attempting to determine the author. However, I can't for the life of me find where I heard this or any link at all. Has anyone heard of something like this? I'd appreciate any links or information that could lead to a link.
