I started my research on citation system with a very positve attitude about that. I have read many of scientometrics papers, but now I am completely disappoined! In the report by the International Mathematical Union (IMU) (attached) about citation statistics. I found an interesting sentence! Citation should not be used for evaluation of different papers in two different disciplines. How about different papers from two different sub-disciplines? and even two different  sub-sub-disciplines? and so on!

On the Web of Science my name appears sometimes as Suo Z and sometimes as Suo ZG.  If I search for Suo Z*, papers by a biologist named Suo ZM mix in.  Now Suo is a very rare name.  I cannot imagine how Wang JS searches for his papers.  Last year Michelle Oyen and I talked about assigning a unique identifier to each researcher, much like assigning an ISBN to each edition of a book, or assigning a DOI to each paper.
