Structural Equivalence

Structural equivalence is as simple as Amazon.com reporting that “People who bought books A and B also
bought books C and D.” Here we consider both people and books as members of a single network. Links in this network join people to the books they have purchased. People who own many of the same books
have a high value of structural equivalence; people with different books have low structural equivalence. For WiserEarth we would be looking at the connections between people and AoFs and people and content (wikipages, resources, solutions, events, jobs).
