Detecting Sarcasm in Multimodal Social Platforms
Table 3: Average number of words, emojis and tags.
['[BOLD] Platform', '[BOLD] #Words', '[BOLD] #Emojis', '[BOLD] #Tags']
Due to its tight character limitation (which also accounts for the hashtags), Twitter is the platform with the shortest text and the lowest number of tags per post. While Tumblr posts are the longest, the average number of tags is similar to that of Instagram, which has in turn the highest tag-to-word ratio. Indeed, Instagram users seem to express heavily through hashtags, especially compared to Twitter users, whose posts have a similar average word count. Both platforms also have a similar emoji-to-word ratio, which is much lower on Tumblr. The fact that there is a character limitation for both Instagram and Twitter might justify the usage of emojis, which are compact representations of concepts and reactions that would be much more verbose if expressed in words.
