Connections between topic areas Semantic bridges
Semantic bridges connect parts of the graph that would otherwise be more separate. A bridge is a structural signal in this analysis, not a claim that the two topic areas are equivalent.
For Zenith Data Systems, one of the stronger structural bridges in this analysis connects Zenith Data Systems with History. Bridges highlight paths between different parts of the map and can reveal research angles that are easy to miss in a flat list.
