ConlluEditor: a fully graphical editor for Universal dependencies treebank files

Abstract

In this paper we present the ConlluEditor annotation tool for manual annotation of files in CoNLL-U format, such as Universal Dependencies treebanks. Apart from providing a graphical editor for basic and enhanced dependencies, multi-token words, it also runs validation scripts to find potential errors. ConlluEditor uses a client-server architecture. It is freely-available under the 3-Clause BSD License.
