ABSSTRACT :
The analysis of hyperlink structure on the Web has been employed for
detecting high quality documents.  Quality may correspond to the authority
of a document, but could also correspond to its utility, that is how well
it enables a user to browse its vicinity.  We present a hyperlink analysis
model, based on modelling the Web graph as an absorbing Markov chain, that
can be employed for both authority and utility analysis of documents.  The
results of experiments for both types of hyperlink analysis underpin the
importance of making this distinction.  In addition, we provide evidence
that support the investigation of more elaborate hyperlink analysis methods
on a query-by-query basis.
