This paper reports our recent work to use visualization to present semantic relation for Chinese WordNet. We design a visualization interface, named CWN-Viz, based on "TouchGraph". There are three import design features of this visualization interface: First, visualization is driven by wordform, the most intuitive lexical search unit in Chinese. Second, the CWN-Viz allows visualization of bilingual semantic relations by incorporating Sinica BOW (Bilingual Ontological WordNet) information. Third, the semantic distance of each relation is calculated and used in both clustering and visualization.
