## What it is
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

## Facets
