내가 관심있는 것은 여기서 Link Farm

Link Fram Detection 기법

Parental Penalty

Wu and Davison [2] proposed a detection method to find link farms. This method consists of
two steps. The motivation behind this method is that pages in a link farms are densely connected
to each other, so pages within link farms usually have several common nodes between the
incoming links set and outgoing links set. If we find a seed set, for a new page, it is possible that
the page is a part of a same link farm. Then we can expand this seed set to find other link farms.
To explain this method briefly, we can say that it first generates a seed set and next expands it to
find link farms. For expansion step they used a method called Parental Penalty which is the
name of the whole algorithm too.
