"WebAbstract. This paper proposes a similarity measure to compare cases represented by labeled graphs. We rst de ne an expressive model of directed labeled graph, allowing multiple labels on vertices and edges. Then we de ne the similarity problem as the search of a best mapping, where a mapping is a correspondence between vertices of the graphs. " - Graph similarity measures
