19. The system of claim 18 , wherein the operation further comprises: monitoring one of the plurality of users: (i) selecting a third information asset presented in the set of search results and (ii) subsequently selecting a fourth information asset presented in the set of search results; upon determining that the third and fourth information assets were selected within a preconfigured time window of one another, increasing a relationship strength between the third and fourth information assets in the semantic graph; and wherein upon determining that the third and fourth information assets were not selected within a preconfigured time window of one another, no relationship strength between the third and fourth information assets is increased in the semantic graph.
