A Java base library from NLPchina that packages common utilities used across NLP projects, such as trie/double-array trie structures, word normalization, sentence splitting, and Viterbi. It also includes components like Chinese-to-pinyin conversion, simplified/traditional Chinese conversion, SimHash similarity, fingerprint deduplication, and in-memory search suggestions.

Use cases

• build a trie or double-array trie in java
• convert chinese characters to pinyin
• convert simplified chinese to traditional chinese
• compute document similarity with simhash
• deduplicate text by fingerprint
• split chinese text into sentences
• word frequency and idf statistics
• in-memory search autocomplete suggestions

When to choose

• you need common Chinese NLP utilities in a JVM project
• you want fast trie-based string lookup structures
• you need pinyin conversion or simplified/traditional Chinese mapping
• you need lightweight text deduplication or similarity without heavy dependencies

When to avoid

• you need modern deep-learning-based NLP pipelines
• you work outside the JVM ecosystem
• you need actively developed features beyond the current utility set
