Looking for Java spell checker library

Question

I am looking for an open source Java spell checking library which has dictionaries for at least the following languages: French, German, Spanish, and Czech. Any suggestion?

Solution 1

Another good library is JLanguageTool http://www.languagetool.org/usage/ It has a pretty simple api and does both spelling and grammar checking/suggestions.

JLanguageTool langTool = new JLanguageTool(Language.AMERICAN_ENGLISH);
langTool.activateDefaultPatternRules();

List<RuleMatch> matches = langTool.check("Hitchhiker's Guide tot he Galaxy");
for (RuleMatch match : matches) {
    System.out.println("Potential error at line " +
        match.getEndLine() + ", column " +
        match.getColumn() + ": " + match.getMessage());
    System.out.println("Suggested correction: " +
        match.getSuggestedReplacements());
}

You can also use it to host your own spelling and grammar web service.

Solution 2

Check out JSpell by Page Scholar, http://www.jspell.com.

Solution 3

Another possible alternative is JOrtho http://jortho.sourceforge.net

I haven't used it yet, but I'm evaluating the current Java Open Source spellcheckers to figure out which one to use.

Solution 4

Look at this: http://code.google.com/p/google-api-spelling-java/

This is a simple Java API that makes it very easy to call Google's spell checker service from Java applications.

I tried it and it works very well.

Solution 5

Have a look at JaSpell. It comes with an internal spell checking engine or you can use aspell. Since the source is available, you can also attach aspell-like engines easily (like Hunspell).

It comes with filters for TeX and XML and it has support for suggestion engines like keyboard distance, common misspellings (where you can define words and their replacements for common typos), Levenshtein distance, and phonetic distance.

This service is not working any more. Seems like Google shut it down.

It looks, Google spell checker doesn't work anymore. When you open the link, It is written on web page that "This project will soon be migrated to Github" - not sure when.

This has a ton of dependencies and is powered by hunspell, which is mentioned in another answer.
