A Python library for Chinese sentiment polarity analysis offering both lexicon-based scoring and classic ML classifiers (k-NN, Bayes, maximum entropy, SVM) with chi-square feature extraction. It can analyze individual sentences or batch files and report per-clause sentiment explanations.

Use cases

• analyze sentiment polarity of Chinese sentences
• classify restaurant reviews as positive or negative
• compare k-NN, Bayes, maxent and SVM text classifiers
• extract sentiment features with chi-square test
• score sentences using a sentiment dictionary
• batch sentiment analysis of text files

When to choose

• you need lexicon-based, explainable sentiment scoring for Chinese text
• you want to experiment with classic ML classifiers on sentiment datasets
• you need per-clause sentiment breakdowns with conjunction handling

When to avoid

• you need actively maintained code or a license
• you need modern transformer-based sentiment models
• you need non-Chinese language support
