document: Communities from seed sets Expanding a seed set into a larger community is a common procedure in link-based analysis . We show how to adapt recent results from theoretical computer science to expand a seed set into a community with small conductance and a strong relationship to the seed , while examining only a small neighborhood of the entire graph . We extend existing results to give theoretical guarantees that apply to a variety of seed sets from specified communities . We also describe simple and flexible heuristics for applying these methods in practice , and present early experiments showing that these methods compare favorably with existing approaches .
