For example, P( teh| the) is relatively high, The probability that w would be typed by a user when the The probability that c appears as a word of English text.įor example, occurrences of "the" make up about 7% of English text, so Thus in this project, we will limit the candidate set \(C\) only to those words that are within edit distance 2 of the user provided input w. A rule of thumb of spelling check is that 75% misspells are within edit distance 1 and 98% are within edit distance 2. When generating the candidate set \(C\), we can make use of the Edit Distance metric. This tells us which candidate corrections, c, to consider. We choose the candidate with the highest combined probability. Since P( w) is the same for every possible candidate c, we can factor it out, giving:

Thus a good way to model the spelling check problem is to use a probabilistic approach we are trying to find the correction \(c\), out of all possible candidate corrections \(C\), that maximizes the probability that \(c\) is the intended correction, given the original word \(w\):

Clearly, given a user input \(w\), there is no way to know its correct spelling \(c\) for sure (for example, should "kives" be "knives" or "hives" or. Given a user-typed word \(w\), the spell checker's job is to find the correct spelling \(c\) of \(w\). In this project, we will learn the basic theory behind how spell checker works and explore different ways of implementing a basic spell checker. With the help of a spell checker, the search engine tries to guess the user's intention and recommends what is likely to be the correct spelling of whatever the user typed.

Many users find that a spell checker is a tool that they cannot live without they mostly know how to spell, but once in a while they experience a time when the correct spelling simply slips their mind. CS246 Project 3: Spell Checker CS246 Project 3 Overview
