A single concern in working with a dictionary of predefined sentiment scores is definitely the concern of context. Basic scores are normally derived from significant corpuses, but topic-specific studies may be sensitive to how certain terms are utilized. Applying a more customised dictionary with improved semantic algorithms could aid create far more precise sentiment scores.Division of Preventive Medicine, University of Southern California, Los Angeles, California, USA Correspondence to Dr Kar-Hai Chu; karhaichusc.eduINTRODUCTION Facts and communication technologies have become part of our daily lives.
