Human encouragement and responses to tail-chasing in dogs on YouTube™.

The percentages of videos are arranged in order of magnitude for each general category. The words that were accepted as valid synonyms for comment categories were shown. These were accepted only if they were consistent within the context of the whole comment, e.g. a comment was not included in the counts for ‘funny’ if the comment actually stated that the video was ‘not funny’, even though the keyword was present in the comment.
