sego is a Go library for Chinese word segmentation using a double-array trie dictionary and a shortest-path-plus-dynamic-programming algorithm. It supports normal and search-engine segmentation modes, user dictionaries, part-of-speech tagging, and can run as a JSON RPC service.

Use cases

• segment Chinese text into words in Go
• tokenize Chinese documents for full-text search indexing
• add custom words to a Chinese segmentation dictionary
• run Chinese word segmentation as an RPC service
• tag parts of speech for segmented Chinese words

When to choose

• you need fast, pure-Go Chinese word segmentation without external dependencies
• you are building a Chinese search engine and need search-mode tokenization
• you want a simple embeddable segmenter with user dictionary support

When to avoid

• you need actively maintained NLP tooling or modern segmentation models
• you need segmentation for languages other than Chinese
• you want deep-learning-based segmentation accuracy
