jieba.NET is a C# port of the popular jieba Chinese word segmentation library, supporting .NET Framework and .NET Core. It offers precise, full, and search-engine segmentation modes, traditional Chinese support, custom dictionaries, and a FlashText-inspired KeywordProcessor.

Use cases

• segment Chinese text into words in a .NET application
• tokenize Chinese sentences for text analysis
• split Chinese text for search engine indexing
• add custom domain words to a Chinese tokenizer dictionary
• extract keywords from Chinese text with case-insensitive matching
• handle traditional Chinese segmentation

When to choose

• you need Chinese word segmentation in C# or any .NET language
• you want API compatibility with Python's jieba
• you need search-engine-mode tokenization for Lucene or full-text search
• you require custom user dictionaries or traditional Chinese support

When to avoid

• you need the latest jieba paddle-mode deep learning segmentation
• you are not on the .NET platform
• you need actively developed features beyond the 2022 release
• you need segmentation for languages other than Chinese
