In particular, we hypothesise that some of our target classes are typified by certain writing styles which differ in their formality and the extent to which they approach informal speech.
we aim to capture the difference between a plainer writing style, with few or no interjections, without abbreviations and/or emojis; and a writing style which more closely approximates speech, making substantial use of exclamation marks and emojis for emphasis, abbreviations, possibly incorrect spelling of words to approximate phonetic form and broad use of direct speech.
