Automatic Annotation Suggestions and Custom Annotation Layers in WebAnno

In this paper, we present a flexible approach to the efficient and exhaustive manual annotation of text documents.For this purpose, we extend WebAnno (Yimam et al., 2013) an open-source web-based annotation tool. 1 While it was previously limited to specific annotation layers, our extension allows adding and configuring an arbitrary number of layers through a web-based UI.These layers can be annotated separately or simultaneously, and support most types of linguistic annotations such as spans, semantic classes, dependency relations, lexical chains, and morphology.Further, we tightly integrate a generic machine learning component for automatic annotation suggestions of span annotations.In two case studies, we show that automatic annotation suggestions, combined with our split-pane UI concept, significantly reduces annotation time.
