No, really, they're serious:
The solution we're creating is simple: an open-source filter software that can detect rampant stupidity in written English. This will be accomplished with weighted Bayesian analysis and some rules-based processing, similar to spam detection engines. The primary challenge inherent in our task is that stupidity is not a binary distinction, but rather a matter of degree. To this end, we're collecting a ranked corpus of stupid text, gleaned from user comments on public websites and ranked on a five-point scale.
Eventually, once the research is completed, we plan to release core engine source code for incorporation into content management systems, blogs, wikis and the like. Additionally, we plan to develop a fully implemented Firefox plugin and a WordPress plugin.
The Stupid Filter Project is the brainchild of Albuquerque's Gabriel Ortiz and Honolulu's Paul Starr. Do read their FAQ, in which they confront the issue of irony in online comments:
What about ironic uses of “stupid” diction?
The StupidFilter is blind to irony. Our intent is that one or two instances of “lol” or “ur dum” in several paragraphs of otherwise-cogent text won't result in a false positive. However, we consider the StupidFilter's irony-ignorance to be a feature, insofar as even if an allegedly-smart person makes a short, stupid comment, their smartness doesn't make the comment any less stupid. If your mom had designed the StupidFilter, she might say “If you can't say anything smart, don't say anything at all.”
To Gabriel and Paul, I say: Good luck, men!
