EasyTree: A Graphical Tool for Dependency Tree Annotation
Alexa Little, Stephen Tratz · 2016
This paper introduces EasyTree, a dynamic graphical tool for dependency tree annotation.With EasyTree, annotators can incrementally construct and label trees by manipulating an interactive graphical tree representation and then exporting the internal data representation as JSON (JavaScript Object Notation).This intuitive animated interface has a number of customizable features to assist annotators, including color-coded part-of-speech indicators and optional translation displays.It can be adapted to suit a range of different projects.Edge labels, part-of-speech categories, and many other settings can be edited from within the GUI.EasyTree uses the standard UTF-8 encoding internally and properly handles both left-to-right and right-to-left scripts.In providing a user-friendly annotation tool, our aim is to significantly reduce the time spent transforming data or learning to use software, to improve the overall user experience for annotators, and to make annotation approachable even for inexperienced users.EasyTree is built entirely with standard web technologies-JavaScript, HTML, and CSS.Thus, it is well-suited for web-based annotation efforts such as crowdsourcing efforts.
