Overview of Sentiment and Intent Analysis
- Sentiment Analysis is termed as contextual mining of text to identify and extract information, understand social sentiment of a brand. It is text classification tool to analyze incoming messages and to depict positive, negative or neutral sentiments.
- Sentiment Analysis using Natural Language Processing involves Supervised Learning, Neural Network Approach. Sentiment Analysis using Deep Learning will include Visual Keras Deep Learning Approach.
- Intent Analysis involves understanding emotions and intent of a user.It involves choosing the right events, tracking behaviour against retention, identification of user's need, bringing Real-Time Data Insights deriving value from Predictive Analytics.Intent Analysis using Automated Text Classification with Machine Learning involves Supervised Text Classification, Unsupervised Text Classification. Intent Analysis using Deep Learning involves Convolutional Neural Networks.
