2. Spelling Correction: On Spelling Correction and the Collective Knowledge of Web Users
Silviu Cucerzan, Eric Brill - Microsoft Research
This is a very nice paper on how spelling correction works on search engines. An extremely nice paper which starts of with very simple techniques based on a language dictionary and then refines it on and on and finally you have techniques that are very less dependent on a language dictionary. The final technique simply uses the collective knowledge of the web users.
