Link Analysis: Citations
(relevance based on author judgments)
•Some citation assumptions
–If A cites (is linked to) B, then more likely that A is related to B than to arbitrary C.
–If A and B are cited by (linked from) C, then A and B are more likely to be related than A or B to arbitrary D.  (co-citation)
–If more objects cite A than cite B, then A is more ‘valued’ than B (citation value)
–If highly ‘valued’ object A cites C and less ‘valued’ object B cites C, then A’s citation is more valuable.
