"PageRank and beyond: the role of hyperlinks in search
engines"


Helye: BME Fizikai Intezet,
Elmeleti Fizika Tanszek
Budafoki ut 8.
F-epulet, III. lepcsohaz, mfszt. Szeminariumi szoba

Kivonat: The idea of using hyperlink mining algorithms in Web search
engines
appears since the beginning of the success of Google's PageRank.
Hyperlink
based methods are based on the assumption that a hyperlink u -> v
implies
that page u votes for v as a quality page. As an example we may
define
Personalized PageRank that assigns more importance to the
neighborhood of
pages at the users selection. SimRank is a multi-step link-based
similarity function has a similar recursive idea that two pages are
similar if pointed to by similar pages.

I will discuss the meaning of these parameters as well as the
challenges
behind computing them for billions of nodes. I will also elaborate
on
how "search engine optimizers" spam these measures as well as show
strategies to filter the so-called Web spam. We will also see
connections
between the hyperlink structure of the Web and social networks.


Minden erdeklodot szivesen latunk.
