11. The computer system of claim 10 , wherein the provenance-based-on-document-content-determiner is configured for determining a Markov chain based on the reversed-in-time graph wherein documents associated with the reversed-in-time graph represent nodes of the Markov chain and probabilities determined based on normalized similarity values are associated with transitions between the nodes.
