    There is, for example, a curious evaluation table provided by a modern ML-based spellchecker JamSpell. According to it, JamSpell is awesome—while Hunspell is a mere 0.03% better than dummy ("fix nothing") spellchecker... Which doesn't ring true, somehow!

    That's a huge topic, which I am planning to cover towards the end of the article series please like and subscribe, but in short: yes, my opinion is that spellchecking is actually a "machine learning problem in disguise", and most of existing dictionaries are more a roundabout way of storing something-not-unlike-models than analytical data.

    But ML approach will raise a question of data availability. What good your "deep learning OSS spellchecker" will do if there aren't good (and open) models for it which cover as much languages as existing Hunspell dictionaries do? And what if adding a bunch of new words requires laborous model retraining? It is not unsolvable, but non-trivial.

    I believe all the giants have something like this inside (I don't think spelling correction in Google search bar is handled with Hunspell, right?), but it is much harder to do as an open tool, ready to embedding into other software.

    There are a notable attempts, though: JamSpell for one (https://github.com/bakwc/JamSpell), which has an open "free" models, and more precise commercial ones; source code is open (maybe also only for using "simplistic" models, haven't dug deeper).

    Obviously, there are open-source spellcheckers other than Hunspell. GNU aspell (that at one point was superseded by Hunspell, but still holds its ground in English suggestion quality), to name one of the older ones; but also there are novel approaches, like SymSpell, claiming to be "1 million times faster" or ML-based JamSpell, claiming to be much more accurate.

  • Why I Stopped Using Sorbet in All My Ruby Projects

    In my experience of working on complicated algorithmic project (spylls spellchecker) in Python after 15+ years of Ruby, I really liked the gradual typing experience: you write dynamic code to get a grip of the logic, and then start to add typing here and there - and it does help to clarify design, catch accidental null possibility, and in general make inter-module API more visible.

    Currently, Spylls has ≈1.5k lines of library code in 14 files. It conforms (with some reservations) to all Hunspell's integrational tests. Those tests look like a set of files each, consisting of "test dictionary + what words should be considered good, what words should be considered bad, what should be suggested instead of the bad words", and there are 127 of such sets to pass. There are 2 thousand comment lines in the code, explaining thoroughly every detail of the algorithm and rendered at the Spylls documentation site; note that besides docstrings at the beginning of each class and method, there are also inline comments in code—that's why the documentation site uses custom theme with inline "Show code" feature.
