"word_feat" (list of string)
tokenized words of last utterance
"raw_word_label" (string)
raw word label
"token_range" (list of tuple)
token ranges of word labels, each tuple contains the start
position index and the end position index
"utterance" (list of string)
raw utterances
"word_label" (list of string)
list of labels of words in last utterance
"doc_label" (string)
doc label for intent classification

"dict_feat" (tuple, optional)
tuple of three lists, the first is the label of each words,
the second is the weight of the feature, the third is the
