thesis we try to find or to develop a new text annotation tool.
tool should provide the best opportunities to render annotations and give the
user the possibility to alter the annotations in the way they are shown.
Therefore, we analyze and compare existing natural language processing (NLP)
tools with regard to the visualization components. We try to figure out which
text annotations are commonly used and how they are visualized in modern tools.
Out of this we can derive the requirements for the tools nowadays. As part of
this work we developed a framework for the text annotation visualization, which
fulfills the most requirements. This framework has been added as the practical
work to this thesis in a digital form.
