Markyt annotation is a Web-based and multi-purpose platform for the annotation of entities and relations. This annotation tool implements the annotation project life cycle and is able to manage interactive and multi-user projects. Novelty lays on the annotation quality assessment tool and the annotation tracking system, which support systematic and on-demand annotation amendment and exhaustive agreement analysis.
