6. Emotion Detection
Emotion Detection , is the synergistic association of emotions also
and technology. Emotion detection seeks to extract finer-grained
emotions such as happy, sad, angry, and so on, from human
languages rather than coarse-grained and general polarity
assignments in Sentiment Analysis, in order to provide fine-grained
decision-making.
Emotions play a very vital role in decisions that people make. To
understand these emotions can open new opportunities for any
business including the consumer goods industry.
Emotions can form the basis to provide recommendations and
improve customer experience at every touchpoint, in-turn
maximizing revenue for the company.
