SnowNLP is a Python library for processing Simplified Chinese text, offering word segmentation, part-of-speech tagging, sentiment analysis, keyword extraction, summarization, pinyin conversion, and traditional-to-simplified conversion. It implements its own algorithms with bundled trained dictionaries, inspired by TextBlob but tailored for Chinese.

Use cases

• segment chinese text into words
• analyze sentiment of chinese product reviews
• extract keywords from chinese documents
• summarize chinese articles
• convert traditional chinese to simplified
• get pinyin for chinese characters
• compute tf-idf and text similarity for chinese corpora

When to choose

• you need lightweight, dependency-free Chinese NLP in Python with pretrained models included
• you want simple sentiment analysis or keyword extraction for Chinese text without heavy frameworks
• you need pinyin conversion or traditional-to-simplified conversion

When to avoid

• you need state-of-the-art Chinese NLP accuracy - modern transformer-based models outperform it
• your sentiment analysis domain is not e-commerce reviews, since training data is mostly shopping reviews
• you need actively maintained software - the last release was in 2020
