9). If we represent th e probabilities of being at different nodes using a vector b, where the coordinate bi is the probability of being at node i, then this update rule can be written using matrix vector multiplication by analogy with what we did in our earlier analyses: b N T b. (14.10).

What we discover i Code 3 of 9 for .NET s that this is exactly the same as the Basic PageRank Update Rule from Equation (14.6).

Since both PageRank values and random-walk probabilities start out the same (they are initially 1/n for all nodes), and they then evolve according to exactly the same rule, they remain the same forever. This justi es the claim that we made in Section 14.3.

. Claim: The probabi lity of being at a page X after k steps of this random walk is precisely the PageRank of X after k applications of the Basic PageRank Update Rule.. And this claim mak USS Code 39 for .NET es intuitive sense. Like PageRank, the probability of being at a given node in a random walk is something that gets divided up evenly over all the outgoing links from a given node and then passed on to the nodes at the other ends of these links.

In other words, probability and PageRank both ow through the graph according to the same process. A Scaled Version of the Random Walk. We can also formulate an interpretation of the Scaled PageRank Update Rule in terms of random walks.

As suggested at the end of Section 14.3, this modi ed walk works as follows, for a number s > 0: with probability s, the walk follows a random edge as before, and with probability 1 s, it jumps to a node chosen uniformly at random. Again, let s ask the following question: if b1 , b2 , .

. . , bn denote the probabilities of the walk being at nodes 1, 2, .

. . , n, respectively, in a given step, what is the probability it will be at node i in the next step The probability of being at node i is now the sum of sbj / j , over all nodes j that link to i, plus (1 s)/n.

If we use the matrix N from our analysis of the Scaled PageRank Update Rule, then we can write the probability update as bi N1i b1 + N2i b2 + + Nni bn or equivalently b N T b. (14.12) (14.

11). This is the same a s the update rule from Equation (14.8) for the scaled PageRank values. The random-walk probabilities and the scaled PageRank values start at the same initial values, and then they evolve according to the same update, so they remain the same forever.

This argument justi es the following claim.. link analysis and VS .NET USS Code 39 web search Claim: The probability of being at a page X after k steps of the scaled random walk is precisely the PageRank of X after k applications of the Scaled PageRank Update Rule..

It also establishe s that, as we let the number of these scaled random-walk steps go to in nity, the limiting probability of being at a node X is equal to the limiting scaled PageRank value of X.. 14.7 Exercises 1. Show the values that you get if you run two rounds of computing hub and authority values on the network of Web pages in Figure 14.15 (i.

e., the values computed by the k-step hub authority computation when we choose the number of steps k to be 2). Show the values both before and after the nal normalization step, in which we divide each authority score by the sum of all authority scores and divide each hub score by the sum of all hub scores.

(It s ne to write the normalized scores as fractions rather than decimals.) 2. (a) Show the values that you get if you run two rounds of computing hub and authority values on the network of Web pages in Figure 14.

16 (i.e., the values computed by the k-step hub authority computation when we choose the number of steps k to be 2).
