Norvig Spellchecker

Overview

The Norvig spellchecker is a spelling correction algorithm created by Peter Norvig, a computer scientist and AI researcher at the Stanford Institute for Human-centered AI. His justification behind creating his spellchecker was to create a simple and expandable way to teach his colleagues how spelling correctors like Google work. This example is not meant to be as accurate as a modern method but attains a respectable accuracy of >75%.
