Abstract
In this paper, we propose a user interface for text and non-text classification. The user interface helps a user revise incorrect classification results without rewriting. The user interface automatically switch between writing mode and revising mode without any interruption, which makes a better interaction between the user and the system. We compare the proposed user interface with a simple interface using check-box for switching between the writing and revising modes. The experimental results show that the average time for revising of the touch interface is shorter than checkbox interface. Users also evaluated the touch interface better than the checkbox interface, since they have to do less step when misclassifications occur.
