Looking for Java spell checker library [closed]

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?

Answer 1

Hunspell looks like it could be of use. It is written in C++ but a java interface according to the home page. Tri-licensed under GPL, LGPL and MPL so you shouldn't have a problem with it.

Answer 2

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.

Answer 3

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.

Answer 4

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.

Answer 5

You can try Suggester. It is open source, free, and supports all of the above listed languages.
