We present WebAnno, a general pur- pose web-based annotation tool for a wide range of linguistic annotations. Web- Anno offers annotation project manage- ment, freely configurable tagsets and the management of users in different roles. WebAnno uses modern web technology for visualizing and editing annotations in a web browser. It supports arbitrarily large documents, pluggable import/export filters, the curation of annotations across various users, and an interface to farming out annotations to a crowdsourcing plat- form. Currently WebAnno allows part-of- speech, named entity, dependency parsing and co-reference chain annotations. The architecture design allows adding addi- tional modes of visualization and editing, when new kinds of annotations are to be supported.
