More and more people use social media on a daily basis in order to express opinions about various topics such as politics, music, lifestyle, environment, or personal matters. This activity produces a massive number of audio-visual data, and text data that need to be further analyzed according to different criteria set in each case. Text data from social media can provide important information about social media users, their identity and preferences, habits, topics discussed and the trends they follow. Deriving such information from social media text is an intriguing task in the fields of text mining, information visualization and natural language processing (NLP) with a wide range of applications in the social sciences and social media analytics. In this special issue, we invite research papers in the broader field of NLP techniques for social media text analysis. The topics of interest include (but are not limited to): Social media text processing for • Sentiment analysis • Stance detection • Trend analysis • Topic modelling • Gender, age, personality identification • Native/non-native language identification • Language variety identification • Mental health modelling • Dementia and frailty identification • Visualization of social media text • Knowledge discovery from social media text Paper Submission Deadline: January 18, 2019 First Decision Notification: March 31, 2019 Revised Paper Submission: May 30, 2019 Final Paper Submission: June 30, 2019 Final Decision Notification: July 30, 2019 Submissions will be made through IJAIT "Online Submission'" System at http://www.editorialmanager.com/ijait/login.asp.
