Pure-ruby spell checker and suggestion engine
The goal of this project is to create a pure-ruby spell checker and suggestion engine. The code is based on the Python code provided by Google's Peter Norvig.
This code is a work in progress. When the rspec tests pass with a > 75% accuracy rate I'll know we have a decent enough word frequency list to make this particular implementation plausible for use. Until then it's more of a toy project.
Right now I provide a script to build a dictionary from either a text file containing words, or a whitespace-delimited file containing words and their associated frequencies. This is in misc/create_dictionaries.rb right now. All it does is load the files into a ruby Hash, and marshal the object out to disk. This dramatically reduces startup time of the speller object as opposed to parsing the entire text file on instantiation.
The main thing is to get the rpsec tests to pass. Then this needs to be formatted to return some decent JSON to throw inside of a web service (such as my toy site, isitaword.com). I also need to morph the create_dictionaries.rb script into a full-blown command line spell checker. Then all I have to do is create the gem and push to gemcutter.
If you have any suggestions, fixes, or whatnot, please submit me a pull request.
