08:26 pm - Google's Context-Sensitive Spell Checker

Wikipedia includes as an example: "Their coming too sea if its reel", a phrase that has 5 spelling mistakes, even though all the words can be found in the dictionary. If you enter this text in Gmail's editor and click on "Check spelling", Gmail won't find any error. Type the same text in Google's search box, and you'll get a "did you mean" message that suggests to search for "Their coming to see if its real". As you can see, Google's search box has a better spell checker than Gmail since it doesn't rely on a dictionary, it uses a huge amount of searches to determine what are the most probable sequences of words that follow a certain pattern. Unfortunately, the spell checker available at Google.com is optimized for searches, which are usually short, so you can't use it to spell check an email message or a blog post.
