1. Create a tokenizer factory and set the token preprocessor:

TokenizerFactory tokenFactory = new DefaultTokenizerFactory();
tokenFactory.setTokenPreProcessor(new CommonPreprocessor());

2. Add the tokenizer factory to the Word2Vec model configuration:
   

Word2Vec model = new Word2Vec.Builder()
 .minWordFrequency(wordFrequency)
 .layerSize(numFeatures)
 .seed(seed)
 .epochs(numEpochs)
 .windowSize(windowSize)
 .iterate(iterator)
 .tokenizerFactory(tokenFactory)
 .build();

3. Train the Word2Vec model:

model.fit();
