While various claims have been made about text in social media text being noisy, there has never been a systematic study to investigate just how linguistically noisy or otherwise it is over a range of social media sources. We explore this question empirically over popular social media text types, in the form of YouTube comments, Twitter posts, web user forum posts, blog posts and Wikipedia, which we compare to a reference corpus of edited English text. We first extract out various descrip-tive statistics from each data type (includ-ing the distribution of languages, average sentence length and proportion of out-of-vocabulary words), and then investigate the proportion of grammatical sentences in each, based on a linguistically-motivated parser. We also investigate the relative similarity between different data types. 1
