Emoji-nized log browser: visualization of server-logs by emoji for system administrators

We propose a log data visualization system by Emoji (pictorial symbol). A log inspection and its monitoring are essential task for system administrators to be aware of anomalous status of the IT systems and security incidents. Information visualization is a promising approach to assist the task. However, there is no visualization work to support understanding the textual data more directly. We, then, propose a text visualization by replacing text data with emoji based on a user-defined rule. In this paper, we explain an idea of visualization by emoji, and we also introduce a prototype system based on the idea for an access log of a web server. We also discuss about expected advantages and future work.
