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 Electro-Voice, one of the stronger structural bridges in this analysis connects Electro-Voice 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.
