A Truth Seal via Predictive Markets

A recent inquiry had me looking at the detection and analysis of 'disinformation'.  Much in and of the news.  That led me to work by Rick Hayes-Roth, who was the CEO of an AI company called Teknowledge that I have written about here before (See tag) .  Teknowledge was one of the AI giants in the late 80s. We used their capabilities, even bought a major equity position with them.  Did some great things, but alas, they are no more.

Around 2011 Hayes-Roth and his colleagues came up with an idea called 'Truth Seals', related to the and driven by Predictive Markets, where you could deliver some measure of the validity of information.  Now needed more than ever.    The startup existed until at 2014 and then folded.  But in my research I noted that Rick, now Prof Emeritus at the Naval Postgraduate School, had written a document that did a post mortem, ala After-Action-Review (AAR) that covered what was done.  Very informative.  Also points to some of the intellectual property developed.    Useful for anyone thinking about the topic.    Reviewing.

I also notice that the idea of 'Predictive Markets' is far less talked about recently, any pointers to work still going on there?
