Rule-Based Sentiment Analysis Algorithm
One is Rule-Based Sentiment Analysis Algorithm. Rule-based algorithms require user to define rules which the system uses to classify unstructured text data based on pre-defined tools. Rule-based requires NLP techniques such as tokenization, Parsing, and Lexicon.
Automated Sentiment Analysis Model
Automated Sentiment Analysis Model is another option which uses algorithms us as linear regression, Naïve Bayes and Deep Learning.
Hybrid Analysis Algorithms
The third one is Hybrid Analysis Algorithms which involves combining the desirable elements of both rule-based and automated machine learning-based algorithms to classify unstructured text to positive, negative and neutral categories.
