摘要：Whatsapp is the most popular social media platform that allows users to interact with each other by sending texts, emoji, images, voice notes, videos etc. Whatsapp users spend hours chatting with each other exchanging information and also sharing intimate feelings that are often touted as deep meaningful conversations. This paper focuses on the study of online social behavior of Whatsapp users which are primarily students in the age group of 18-25 years. 300Whatsapp chats from 30 university students have been collected and scrutinized to determine their online behavior in terms of being expressive on Whatsapp or not and also identifying their general mood on Whatsapp based on their emotional manifestation in the chats. This analysis can be of compelling interest to various psychological researchers, social media influencers and counselors.
