A Java toolkit for computing text similarity at word, phrase, sentence, and paragraph levels, offering algorithms like Cilin-based similarity, edit distance, cosine similarity, Jaccard, SimHash, and more. It also includes Chinese sentiment analysis, lexicon-based word tendency scoring, and word2vec-based near-word lookup.

Use cases

• compute similarity between two Chinese words or sentences in Java
• find duplicate or near-duplicate paragraphs with SimHash or cosine similarity
• score the sentiment polarity of Chinese words
• compare strings with edit distance or Jaro-Winkler in a JVM app
• find semantically similar words using a Chinese thesaurus
• build a deduplication or matching feature for Chinese text

When to choose

• you need text similarity computation in a Java/JVM project
• you work with Chinese text and want thesaurus- or Hownet-based semantic similarity
• you want multiple similarity algorithms behind one simple API
• you need lightweight, dictionary-based sentiment tendency scoring

When to avoid

• you need neural embedding-based similarity (e.g., BERT/sentence transformers) rather than lexical/semantic-dictionary methods
• your primary language is not Chinese and you need multilingual semantic similarity
• you work in Python or another non-JVM stack
