JFastSpell

JFastSpell is a Java wrapper of FastSpell, the most performant, publicly available language detection module by 07/23/2024.

I have no prior knowledge of Java. Please let me know if you have any issue.

Dependencies

• Bazel
• Gson
• JFastText
• HunSpell JNA (This might also work, but it hasn't been maintained for 7 years.)

Setup

1. Download lid.176.bin model from FastText and put it in the src/main/resources folder of your project.

2. Download the fastspell_dictionaries folder and put it in the src/main/resources folder of your project. Make sure the folder name uses an underscore _ instead of -.

3. Make sure that the contents of hunspellCodes.json and similarLangs.json in the src/main/resources folder matches the contents of the .yaml configurations here.

4. Build the aforementioned dependencies and put the .jar files in the dependencies folder at project root:

gson-2.11.0.jar
hunspell-2.2.0.jar
jfasttext-0.5-jar-with-dependencies.jar

5. (optional) Modify your configurations in src/main/resources/config.json if necessary.

Build

Make sure that you have successfully installed Bazel. Go to the project root directory. Build FastSpell:

bazel build //:FastSpell

Then test it with an arbitrary input sentence:

bazel-bin/FastSpell YOUR_SENTENCE_HERE

Usage

FastSpell fs = new FastSpell();
String lang = fs.getLang("Hello world!");
System.out.println(lang);
