Abstract:
1. A method for ranking pages using DNS data, the method comprising: obtaining ISP DNS data for a particular session; identifying one or more sequences of host requests based on the ISP DNS data; and using a computing device to rank ranking pages and/or hosts based at least in part on the identified sequences of hosts, wherein ranking pages comprises: calculating a global host rank vector for hosts in the session; calculating a local page rank vector for pages of each host in the session by applying the page rank model to only the hosts visited, wherein the local page rank vectors are calculated prior to, subsequent to, or concurrently with the calculation of the global host rank vector, wherein said local Page rank vectors are pre-computed for certain hosts and combined with dynamically obtained host rank vectors to provide a global page rank on-the-fly; and approximating a global page rank vector based on a combination of the global host rank vector and local page rank vector based a dynamic traffic flow model and/or static page ranking model.
