Edit Distance Algorithms
You can help improve this README with extra snippets and advice by using the GitHub wiki.
To just install the library:
runghc Setup.lhs configure runghc Setup.lhs build sudo runghc Setup.lhs install
If you want to build the tests, to check it’s all working:
runghc Setup.lhs configure -ftests runghc Setup.lhs build dist/build/edit-distance-tests/edit-distance-tests
Edit distances algorithms for fuzzy matching. Specifically, this library provides:
They have been fairly heavily optimized. Indeed, for situations where one of the strings is under 64 characters long I use a rather neat “bit vector” algorithm: see the authors paper and the associated errata for more information. The algorithms could be faster, but they aren’t yet slow enough to force me into improving the situation.
