simple measurement of correlation. In summary, if a query contains the keywords W1, W2 ,..., Wn, which have the following frequencies on a specific webpage: TF1, TF2 ,..., TFN. (TF: Term Frequency ). Then, the correlation between this query and the webpage is:TF1 + TF2 +... + TFN.Readers may have discovered another vulnerability.

a good illustration of this. For different pages of the link, PR is treated differently: that is, the high-ranking Web site contribution to the right link. So how to calculate the weight of the page?There are x1, x2, x3, x4 four pages only want to page y, four pages corresponding to the weights are 0.001, 0.01, 0.02, 0.05, then the page y pr=0.001+0.01+0.02+0.05=0.081. The calculation of the PR algorithm is the multiplication of matrices in linear algebra.2. Relevance of Web pages and queriesA

Scripts written in Bash can also be debugged, just like Python,perl and other interpreted languages. Create a new script named Servinfo and add executable permissions:
Copy Code code as follows:
$ VI Servinfo
#!/bin/bash
echo "Hostname: $ (Hostname)"echo "Date: $ (date)"echo "Kernel: $ (Uname-mrs)"
$ chmod +x Servinfo
With Bash-x to debug the above script, bash prints each line of script first, then prints out the results of each line of script:
