Abstract:
Methods for improving sponsored search revenue are often
tested or deployed within a small submarket of the larger
marketplace. For many applications, the ideal submarket
contains a small number of nodes, a large amount of spending
within the submarket, and a small amount of spending leaving
the submarket. We introduce an efficient algorithm for
finding submarkets that are optimal for a user-specified tradeoff
between these three quantities. We apply our algorithm
to find submarkets that are both dense and isolated in a
large spending graph from Yahoo! sponsored search.
