Annotation tools features overview. Each of the selected twenty annotation tools is evaluated based on 24 criteria: 7 technical (T) criteria, three criteria about input and output data formats (D), and 15 criteria concerning the functionalities (F) provided by each tool. The first 22 criteria are taken from [10], while we added the last two. Each criterion is marked in blue for each tool if the feature is fully satisfied, light blue if partially satisfied, and white if not satisfied
