Abstract. In this demo we introduce ESub, a tool aimed at visualizing the outcome provided by a frequent subgraph mining algorithm, i.e. SUBDUE. Such a tool has been developed as a supporting tool for a methodology we proposed in previous works for analyzing unstructured processes, based on the use of graphs. By exploiting graphs-based techniques, it is possible to provide the user with a different perspective on a process, where only the most relevant subprocesses (i.e., subgraphs) are displayed, rather than the complete, end-to-end process schema, which often results very chaotic in unstructured domains. Our tool allows the user to visualize and interact with such subgraphs. Furthermore, it allows for visualizing the original graphs of the set, and compress them by means of the most relevant subgraphs, in order to obtain a simplified view of the overall process. 1 SubProcesses Analysis Process Mining (PM) methods are aimed at extracting from an event log a process schema describing...
