Stupid Filter is a open source code that detects and filters stupid or impertinent remarks on websites, is now available. The creators, who have managed to mount a finance company, on July 29, 2008 launched the first version.
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 or similar 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.
