## What it is
SCWS (Simple Chinese Word Segmentation) is a dictionary-based mechanical Chinese word segmentation engine written in pure C, with no external dependencies, supporting GBK and UTF-8 encodings. It ships as a C library (libscws), a command-line tool, and a PHP extension for fast tokenization of Chinese text.

## Use cases
- segment Chinese text into words for search indexing
- extract keywords from Chinese documents in PHP
- tokenize Chinese text from the command line
- build a small Chinese full-text search engine
- split Chinese strings into words for NLP preprocessing
- embed a lightweight C segmentation library into an application

## When to choose
- you need fast, dependency-free Chinese word segmentation in C or PHP
- you are building a small search engine or keyword extractor for Chinese text
- you want a mature, lightweight tokenizer without heavy ML dependencies

## When to avoid
- you need state-of-the-art accuracy on complex modern Chinese text
- you want a pure PHP solution without compiling C extensions
- you need segmentation for languages other than Chinese

## Facets
- artifact type: library
- maturity: maintenance
- function: nlp, search-engine, parser, cli
- domain: developer-tools
- platform: windows, php, cpp, c, cli
- tags: chinese-word-segmentation, text-segmentation, php-extension, dictionary-based, keyword-extraction, full-text-search, natural-language-processing, search, linux, macos
