History to Myths: Social Network Analysis for Comparison of Stories over Time

We discuss on how related stories can be compared by their characters. We investigate character graphs, or social networks, in order to measure evolution of character importance over time. To illustrate this, we chose the Siegfried-Sigurd myth that may come from a Merovingian king named Sigiberthus. The Nibelungenlied, the Volsunga saga and the History of the Franks are the three resources used.
