The BC3 Annotation Software: An open-source tool for annotating email thread or other conversations

The BC3 corpus was annotated using a web-based annotation framework. This framework is open-sourced and is available for download for conversation annotation. The framework is built with Ruby on Rails and a MySQL database so that a web server can be set up that lets researchers import and manage an email corpus. It also lets users annotate emails threads for summaries and label email features.
