HanLP is a natural language processing library and deep learning framework specifically optimized for the Chinese language, while also functioning as a multilingual text processor. It serves as a toolkit for performing linguistic analysis, semantic understanding, and script conversion.
The project distinguishes itself through a dedicated focus on Chinese linguistic structures, including a specialized script converter for transforming text between Simplified Chinese, Traditional Chinese, and Pinyin. It further supports domain-specific model training to improve the recognition of professional terminology within specialized datasets.
Its broader capabilities cover information extraction via named entity recognition and text summarization, as well as comprehensive linguistic analysis including part-of-speech tagging and dependency syntax parsing. The toolkit also provides semantic analysis for sentiment detection and coreference resolution, alongside text transformation utilities for grammar and style conversion.
