Error Model
Understand how error models form the core of spellchecker accuracy by estimating the likelihood of misspelling types such as letter errors, homophones, and keyboard mistakes. Learn to develop a simple error model that prioritizes corrections based on edit distance, integrating this approach with candidate selection in spellchecking systems.
We'll cover the following...
What is an error model?
In a spellchecker, an error model is a statistical model that estimates the probability of different types of errors that may occur when a user misspells a word. The error model helps the spellchecker generate a list of candidate corrections that are likely to represent the intended word, despite the error.
The specific approach used to develop an error model can vary, but it generally involves analyzing a corpus of text to identify common patterns of errors. For example, an error ...
