1. PageRank (PR) is an algorithm used by Google Search to rank websites in their search engine results. PageRank was named _________________
2. Read this excerpt - provided by Google - and fill in the blanks.
3. Currently, PageRank is the only algorithm in the world used to order search results
4. Analyse the following image that shows mathematical page ranks for a simple network. Which of the following statements are correct?
5. Because of the size of the actual web, the Google search engine uses an approximative, iterative computation of PageRank values
6. The size of each face is proportional to the __________________________ (This demonstrates page rank)
7. PageRank is a link analysis algorithm and it assigns a _______________ to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of "measuring" its relative importance within the set
8. A ____ is a page with many out-links
9. A _____ is a page with many in-links
10. Read the following excerpt and analyse the image on page ranking. Fill in the blanks
Assume the web consists of five websites: Twtr, Amzn, Fb, Medm, and Mspc.
Also assume that these sites are linked. For example, the Fb may link to
Amzn, and Amzn may link to somewhere else
Initially, there is no order preference, that is each page has an equal
probability of getting the highest rank.
In other words, each page is initialized with a rank of 1/N,
where N is the total number of webpages in the graph.
In this example, each webpage would start with a ______________
11. Page Rank or PR(A) can be calculated using a _______ algorithm.
12. Read the excerpt below and select the statement that best fits the blanks
13. This is where it gets tricky. The PR of each page depends on the PR of the pages pointing to it. But we won’t know what PR those pages have until _______________
14. Have a look at the formula for the page rank algorithm. Fill in the blanks
15. The PageRank of page A is ____________ defined by the PageRanks of those pages which link to page A
