Sentiment analysis using novel and interpretable architectures of Hidden Markov Models

作者:

Highlights:

• We introduce Hidden Markov Models for sentiment analysis.

• The introduced HMMs have high interpretability and visualize the decisions made.

• They show the way that sentiments change from the start to the end of sentences.

• Different architectures, orders, ensembles and training methods are examined.

• The introduced HMMs outperform traditional HMMs and machine learning methods.
