  Editor
Khanh Duy Nguyen Zixuan Zhang Reece Suchocki Sha Li Martha Palmer Susan Brown Jiawei Han Heng Ji
In this paper, we present RESIN-EDITOR, an interactive event graph visualizer
and editor designed for analyzing complex events. Our RESIN-EDITOR system
allows users to render and freely edit hierarchical event graphs extracted from
multimedia and multi-document news clusters with guidance from human-curated
event schemas. RESIN-EDITOR's unique features include hierarchical graph
visualization, comprehensive source tracing, and interactive user editing,
which is more powerful and versatile than existing Information Extraction (IE)
visualization tools. In our evaluation of RESIN-EDITOR, we demonstrate ways in
which our tool is effective in understanding complex events and enhancing
system performance. The source code, a video demonstration, and a live website
for RESIN-EDITOR have been made publicly available.
