SWAN: an easy-to-use web-based annotation system

We present the Saar Web ANnotation system (SWAN), a lean web-based annotation system, which is optimized for annotator and project management usability.1 SWAN is well-suited for various discourse annotation tasks, as arbitrarily large documents can be annotated seamlessly due to dynamic loading and rendering. A graphbased visualization box supports the user by providing both an overview of the existing annotations and a navigation option through the text. The admin view includes the web-based configuration of projects, annotation schemes and users. SWAN is based on JEE technology and compatible with several web browsers.
