Natural Language Processing for State Security

    Yeah, because we need AT&T giving wide-scale, undocumented wiretaps to the NSA, who use voice recognition to generate transcripts of everyone's phone calls, and then DHS can run NLP on those transcripts to compile a list of "persons of interest", who are then automatically added to the TSA no-fly lists.

    Yeah, I can envision the future, and the future sucks.

      It's the "narrow domains" that is the crux of the problem.

      When used successfully over said "narrow domains", the human tendency (especially that set of humanity which makes the high-level choices for groups and organizations) will be to expand the domain in hopes of applying it to ever greater numbers of items.

      Of course, as the search domain is expanded, the effectiveness of the results decline, with no warning to the clueless idiots driving the search. False positives eventually exceed true positives by greater and greater margins.

      In the end, the strategy collapses, as a great many victims are shown to be wrongly targeted -- but until that point, the system does a LOT more harm than good.

      Thank Goodness our leaders are such wise and contemplative souls that they would never, ever misuse such a tool.

    Funny, because neither of the articles state that. In fact, they don't even say that software can do that at all yet: A new research program ... aims to teach computers to scan through text and sort opinion from fact. Or, We're interested in seeing how we would extract information about opinions.

    So yeah, it would be nice if they could sort opinions from facts. Why they're at it, why don't they just recognize lies from truth too, because wouldn't that be doing the exact same thing? Then we can just run statements made by people suspected of committing a crime through the software, which can then sort out all the facts from the opinions, and we'll no longer need judges, juries or attorneys.
