One concern in working with a dictionary of predefined sentiment scores is the situation of context. Basic scores are usually derived from significant corpuses, but topic-specific studies could be sensitive to how certain terms are utilized. Applying a far more customised dictionary with improved semantic algorithms could support produce much more correct sentiment scores.Division of Preventive Medicine, University of Southern California, Los Angeles, California, USA Correspondence to Dr Kar-Hai Chu; karhaichusc.eduINTRODUCTION Info and communication technologies have turn into part of our each day lives.
