## 项目历史与用法

CRFsuite is Naoaki Okazaki's fast implementation of Conditional Random Fields for labeling sequential data. It provides command-line training/tagging, C++ and SWIG APIs, and training algorithms such as L-BFGS, OWL-QN, SGD, averaged perceptron, passive aggressive, and AROW.

### 项目历史

The official changelog records internal releases beginning with CRFsuite 0.1 on 2007-10-29 and a first public release, 0.4, on 2008-03-05. The 0.4 release added the website, documentation, a tutorial, and a CoNLL 2000 chunking performance comparison.

### 采用历史

The project page presents CRFsuite as a faster and more flexible CRF package than older template-oriented tools, with a simple data format, benchmark results, and model storage based on CQDB. Version 0.12 added Python SWIG modules and sample programs, including named entity recognition and part-of-speech tagging examples.

### 使用方式

CRFsuite users train and tag sequence-labeling models with a feature-per-line data format. The official documentation emphasizes speed, training-method choice, performance evaluation during training, and programmatic use through C++ and SWIG APIs.

### 为什么软件包爱好者会关心

For package maintainers, CRFsuite is a compact C/C++ NLP toolkit with historical source and binary releases, a BSD license, and a small command-line surface. It is also useful as a contrast point with CRF++ because its official page calls out data-format flexibility that CRF++ lacks.

### 时间线

- 2007-10-29: CRFsuite 0.1 internal release
- 2008-03-05: CRFsuite 0.4 first public release
- 2009-03-07: Version 0.6 added SGD and reduced training memory usage
- 2011-08-11: Version 0.12 optimized training, added more algorithms, revised APIs, and added Python SWIG support

### Related projects

- The official page links CRFsuite's data-format comparison to CRF++, and also points to libLBFGS and CQDB as implementation-related software.
