New Algorithm Recognizes Both Good and Bad Fake Reviews (thestack.com) 59

An anonymous reader writes: Researchers from the university of Sao Paolo have developed an algorithm able to identify both good and bad online reviews in the massive daily chatter of millions of peer-community posts, and in lateral mendacities at social network sites such as Google+ and Facebook reposts and 'likes'. Two of the datasets tested in the research were from Amazon, which has a vested interest in restoring the reputation of its community reviews, and has recently taken action on the matter.

  • With Siskel and Ebert now gone, my bot is picking up the slack: it gives this concept two thumbs down.

    While I have spent a lot of time studying algorithms, I still like to look for new algorithms from time to time. This algorithm is definitely one of the better algorithms I have come across in my life.

    When I first started studying the algorithm, I wasn't sure whether it was for me. However, after the first few pages, the algorithm began to grab my attention, and soon I was finding its average and worst case complexity and formally proving the correctness of several subroutines. I was astounded to find that it was at least as good as all the other algorithms I'd found over my twenty years' experience.

    While I wouldn't recommend this algorithm to a beginner without guidance, the journeyman will soon find themselves reaching master by applying this algorithm. The master cannot fail to learn something new from it.

    • Hey, that's pretty good! But it seems just a bit too...well...polished if you're actually satirizing something like this:

      hey mama bebs, first of all thanks for drppion on my super unattended blogs and I may not be the perfect person to send replies back the soonest its better late than not doing it all. Anyhoo..we have our disagreements in life,perspectives etc etc..but nevertheless when it concerns to friendship it is always seemed hard to explain. Whether we like it or not, the truth hurts. But just do what you love to do and don’t expect things turn out that way it supposed to be is a great thing to do..let’s talk. have a great one!

      The preceding is actual comment spam from one of my websites. Evidently, the bot was programmed by someone who doesn't speak English very goodly.

      I bought this algorithm based on Anonymous Cowards review; and while I was at first disjointed I persisted until it gave results like no other algorithm before it. While parts of me may still be unhappy, the rest of me is feeling very fulfilled that I made the right algorithm choice. Thanks Anonymous.

    • Algorithm contained bobcat. Would not implement again, although I could only be impressed by how they managed to get it to fold up so small.

  • New Algorithm Recognizes Both Good and Bad (Fake Reviews): The algorithm recognizes good fake reviews and bad fake reviews, but not real reviews.
    New Algorithm Recognizes Both Good and (Bad Fake) Reviews: The algorithm recognizes good reviews and bad fake reviews, but no real bad reviews or fake good reviews.

    Just return true all the time. Sure there will be a few false positives but not enough to throw the results off by much.

    It combines orgasmic whitefish essences and loud mustard overtones with a stale nacho aftertaste.
  • Part of what makes me come back to Amazon's site to buy products is the humorous fake reviews for things that are absurdly expensive or seems like it shouldn't exist.

      Don't worry Amazon is just interest in rebuilding the 'reputation' of their reviews and not in the actual real genuiness or accuracy of the reviews, they just want to believe the reviews and buy junk. So they are basically engaging in a public relations exercise to give their reviews a positive review because so many people have given up on IMDB because the publicly accepted default review is a 10 out of 10 by a one off 'er' reviewer, so bad that it IMDB unusable as a movie review system. Basically skip the first bunch of pages (seriously up to and over 10 pages) as PR bullshit to get to real actual reviews.

  • If you haven't seen this, there is a service that looks at reviews to find if they are fake or not: http://fakespot.com/ [fakespot.com] From what I can gather about them, they also use clustering algorithms to detect the fake Amazon reviews.
    • Useless. I directed it to a book with 467 reviews. It claimed where were not enough reviews to analyse.

    actually "Universidade de São Paulo", located in the city and state of the same name. I get that you anglophones don't go well with tildes [and for that you are excused], but don't change so drastically the name of my town/state.

  • The only way Amazon could restore the reputation of their reviews would be to change from the bad it's always been to something better (because it couldn't get any worse), then make it bad again.
