Abstract — Real-time visualization of text streams is crucial for different analysis scenarios and can be expected to become one of the important future research topics in the text visualization domain. Especially the complex requirements of real-time text analysis tasks lead to new visualization challenges, which will be structured and described in this paper. First, we give a definition of what we consider to be a text stream and emphasize the importance of different real-world application scenarios. Then, we summarize research challenges related to different parts of the analysis process and identify those challenges that are exclusive to real-time streaming text visualization. We review related work with respect to the question which of the challenges have been addressed in the past and what solutions have been suggested. Finally, we identify the open issues and potential future research subjects in this vibrant area. Index Terms—real-time, text streams, streaming data, dynamic visualization, visual analytics. 1
