8. A method comprising: under control of one or more processors configured with executable instructions: obtaining web documents based at least in part on a search term; extracting a plurality of entities and entity relationships from the web documents, each of the plurality of entities related to, but distinct from, the search term; clustering relationship data obtained by extracting the entity relationships; causing display of representations indicating each of the plurality of entities, wherein the representations are grouped together on the display based at least in part on the clustering such that representations having the same or similar relationship data are closer together than representations not having the same or similar relationship data; causing display of edges to define pairs of the displayed representations, the edges indicated by the entity relationships; causing display of a representation of the search term and edges from the representation of the search term to each of the representations of the plurality of entities.

The method as recited in claim 8 , wherein the causing display of representations indicating each of the plurality of entities comprises: causing display of representations of entities connected by edges to more entities in a size larger than representations of entities connected by edges t fewer entities; and causing display of the representation of the search term in a size larger than representations indicating each of the plurality of entities.
