Instructions: Given an input stream, the objective of this task is to classify whether words in the stream are grammatically correct or not. The input to this task is a stream of words, possibly from captions generated by a speech-to-text engine, and the output is a classification of each word from the labels (reason) = [NO_DIFF (correct), CASE_DIFF (case error), PUNCUATION_DIFF (punctuation error), CASE_AND_PUNCUATION_DIFF (both case and punctuation error), STEM_BASED_DIFF (stem word error), DIGIT_DIFF (digit error), INTRAWORD_PUNC_DIFF (intra-word punctuation error), and UNKNOWN_TYPE_DIFF (an error that does not corrrespond to the previous categories)].
Input: ['currently', 'a', 'local', 'newspaper', 'company', 'sells', 'print', 'subscriptions', 'for', '$9', '30', 'cents', 'a', 'month', 'and', 'has', '2400', 'subscribers', 'based', 'on', 'a', 'survey', 'conducted', 'they', 'expect', 'to', 'lose', '20', 'subscribers', 'for', 'each', '10', 'cent', 'increase', 'from', 'the', 'current', 'monthly', 'subscription', 'price', 'all', 'right', "that's", 'interesting', 'what', 'should', 'the', 'newspaper', 'company', 'charge', 'for', 'a', 'monthly', 'subscription', 'in', 'order', 'to', 'maximize', 'the', 'income', 'in', 'order', 'to', 'maximize', 'the', 'income', 'from', 'the', 'print', 'newspaper', 'subscriptions', 'so', "let's", 'take', 'a', 'little', 'bit', 'about', 'their', 'income', 'but', "it's", 'actually', 'their', 'revenue', 'how', 'much', 'money', "they're", 'bringing', 'in', 'but', 'I', 'get', 'what', "they're", 'talking', 'about', 'so', 'their']
