similarity influenced ranking

Hi,
   Anybody knows a method that I can use to have things (i.e., entities,
property-value pairs) ranked based on similarity? For example, I have a
basic rank score and I want to boost this score based on similarity of
things to each other in the graph. PageRank is abit different to what I
have in mind and Similarity Flooding approach is about aligning things
between two graphs. Any thoughts along this line? Thank you in advance.
