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: ['a', 'cellphone', 'producer', 'distributes', 'boxes', 'of', 'units', 'to', 'retail', 'stores', 'a', 'unit', 'is', 'either', 'a', 'cell', 'phone', 'or', 'an', 'accessory', 'and', 'each', 'box', 'can', 'have', 'up', 'to', '24', 'units', 'composed', 'of', 'C', 'cell', 'phones', 'and', 'a', 'accessories', 'in', 'addition', 'each', 'box', 'must', 'have', 'at', 'least', 'as', 'many', 'cell', 'phones', 'as', 'accessories', 'at', 'least', 'as', 'many', 'cell', 'phones', 'as', 'accessories', 'which', 'are', 'the', 'following', 'systems', 'of', 'inequalities', 'best', 'models', 'the', 'situation', 'described', 'above', 'so', "let's", 'just', "let's", 'just', 'think', 'it', 'through', 'so', 'each', 'box', 'can', 'have', 'up', 'to', '24', 'units', 'composed', 'of', 'C', 'cell', 'phones', 'and', 'a', 'accessories', 'so', 'that', 'means']
