Definition: 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: ['it', 'begins', 'with', 'a', 'large', 'tortilla', 'cut', 'a', 'strip', 'from', 'the', 'middle', 'where', 'its', 'widest', 'and', 'free', 'this', 'long', 'rectangle', 'from', 'the', 'useless', 'wedges', 'that', 'surround', 'it', 'this', 'is', 'how', 'we', 'start', 'our', 'journey', 'towards', 'creating', 'the', 'perfect', 'food', 'the', 'hardest', 'part', 'is', 'folding', 'an', 'angle', 'of', 'equal', 'thirds', 'but', 'if', 'you', 'folded', 'a', 'piece', 'of', 'paper', 'into', 'thirds', 'for', 'a', 'letter', 'or', 'pamphlet', 'you', 'know', 'the', 'principle', 'approximate', 'and', 'then', 'adjusts', 'until', 'you', 'reach', 'equality', 'in', 'the', 'case', 'of', 'the', 'tortilla', 'to', 'get', 'an', 'equilateral', 'triangle', 'you', 'fold', 'an', 'angle', 'rather', 'than', 'an', 'edge', 'be', 'sure', 'your', 'folds', 'meet']
