Online platforms allow users to masquerade themselves; making virtual interactions anonymous or misleading recipients of the interactions. It also facilitates
an environment for cybercrimes, allowing users to take advantage of others and
commit heinous acts. An important concern on social media usage, in particular,
has to do with the security of under-age users that have access to the Internet.
Children are more vulnerable to threatening situations, such as harassment,
cyberbullying, and inappropriate conversations. Natural language processing (NLP) techniques can be used to process and understand social media data. In the area of sociolinguistics, there is evidence that links natural word use to
personality and social fluctuations. In NLP, the term burstiness is used to describe the tendency of word recurrence. The burstiness phenomenon is frequently
exhibited in real text, in which an informative word is more likely to occur if it
has already appeared in the text. State-of-the-art NLP models, such as the
multinomial Naive Bayes model, are often used to model text documents.
