Arguments

...

vocabulary objects created with create_vocabulary.

combine_stopwords

function to combine stopwords from input vocabularies. By default we take a union of all stopwords.

combine_ngram

function to combine lower and upper boundary for n-grams from input vocabularies. Usually these values should be the same, so we take this parameter from first vocabulary.

combine_sep_ngram

function to combine stopwords from input vocabularies. Usually these values should be the same, so we take this parameter from first vocabulary.

Value
