Also, page rank is found in http://www.cs.sjsu.edu/faculty/pollett/ ... ml#%285%29 and HITS is found in http://www.cs.sjsu.edu/faculty/pollett/ ... ml#%284%29.

To calculate page rank: use r(Pi) to get r(P) by using the power method for computing eigenvalues,

To calculate HITS: calculate two scores, the authority score and the hub score. To get the hub score, multiply the matrix of the page with the authority weight vector. To get the authority score, multiply the transpose matrix of a page with the hub weight vector.

A XML namespace is the definition for an XML language.

A XML schema or DTD is the definition for a XML language. On the other hand, a XML namespace is the URI (unique resource identifier) which references that particular language. By using namespaces, there is no ambiguity between elements or attributes with the same name.

I had trouble figuring out the meaning of XML namespace for languages. so I looked in http://www.w3schools.com/schema/schema_schema.asp and it says that when you declare a namespace, you are saying that" all the elements used in the document are used in the namespace" (near the bottom). Hope that helps.
