HanLP 是由一系列模型和算法组成的Java工具包。目标是普及自然语言处理在生产环境中的应用。它不仅是分词，还提供了词法分析、句法分析、语义理解等完整的功能。HanLP 具有功能齐全、性能高效、结构清晰、语料最新、功能可定制等特点。  
HanLP 是完全开源的，包括字典。不依赖其他jar，底层使用了一系列高速数据结构，如双数组Trie树、DAWG、AhoCorasickDoubleArrayTrie等，这些基础组件都是开源的。  
通过工具类HanLP，可以一句话调用所有函数，文档详细，开箱即用。底层算法经过精心优化，极速分词模式下每秒可达2000万字，内存仅需要120MB。IO方面，字典加载速度极快，快速启动仅需500ms
