PageRank: An Improvement • Let P be the Markov matrix of the web graph W • What is the sum of entries in the i-th row of P T • The sum of weights of links pointing to node i • This is precisely the importance of node (web page) i • Computing the importance of every node is just computing x = P T J where J is the vector of all 1’s
Exercise 4 • Compute the importance of all the nodes in the “web graph” 1 2 3 4 5 6
