Word detection without separating spaces


Sandor Szatmari
 

You know how apple apps can turn ‘itwas’ into ‘it was’ as your typing in a text field? Is there an API for this? I’d like to be able to take something like AREALLYLONGSTRING and turn it into ‘a really long string’ or ‘a_really_long_string’ or basically insert whatever separator I want.

Something like -(NSString*)componentsSeparatedByDictionaryWord:(NSString*)string;

Does my magical imaginary API exist? I’d imagine it’s part of autocorrection functionality…

Thanks,
Sandor

Some quick googlage suggests that UITextChecker (iOS) and NSSpellChecker (Mac OS) might fit the bill...?

Yes, thanks! I have been playing with NSSpellChecker but haven’t been able to configure it with the magic sauce to get it to tokenize the way I am describing.

You could try taking the first n characters of a word (where n is 1 to maximum word length) and spell checking that string. When you a string that spell-checks, continue for the next n characters, and so on. If you get to a point where you can’t find a word for the remaining characters, backtrack and look for a longer word in the previous characters.

Some strings might have multiple answers:

findale could be find ale or fin dale

NSLinguisticTagger provides a lot of operations like finding word boundaries and identifying parts of speech. I don’t know if it can be made to identify English words without spaces between them.* Apple has added some newer APIs that use machine-learning to analyze natural language, but I can’t remember what the framework is called; maybe it has some support for that?

* It does, however, detect word breaks in East Asian languages that don’t put any separator characters between words.
