Algorithm to calculate a page importance based on its views / comments

Question

I need an algorithm that allows me to determine an appropriate field for my website\'s sitemap based on the page\'s views and comments count.

Answer 1

The most naive approach would be the following:

Let v[i] the views of page i, c[i] the number of comments for page i, then define the relative view weight for page i to be

r_v(i) = v[i]/(sum_j v[j])

where sum_j v[j] is the total of the v[.] over all pages. Similarly define the relative comment weight for page i to be

r_c(i) = c[i]/(sum_j c[j]).

Now you want some constant parameter p: 0 < p < 1 which indicates the importance of views over comments: p = 0 means only comments are significant, p = 1 means only views are significant, and p = 0.5 gives equal weight.

Then set the priority to be

p*r_v(i) + (1-p)*r_c(i)

This might be over-simplistic but its probably the best starting point.
