How to use

The model works at the token level, so you must put it after tokenization. The model can change the length of the tokes when correcting words, so keep this in mind when using it before other annotators that may work with absolute references to the original document like NerConverter.

assembler = DocumentAssembler()\
 .setInputCol("value")\
 .setOutputCol("document")

tokenizer = RecursiveTokenizer()\
 .setInputCols("document")\
 .setOutputCol("token")\
 .setPrefixes(["\"", """, "(", "[", "\n", ".", "l'", "dell'", "nell'", "sull'", "all'", "d'", "un'"])\
 .setSuffixes(["\"", """, ".", ",", "?", ")", "]", "!", ";", ":"])

spellChecker = ContextSpellCheckerModel("spellcheck_dl", "it").\
    setInputCols("token").\
    setOutputCol("corrected")
