I noticed that ranking of scientists in a field or subfield is supplied by Academic Search.
This idea is wonderful.
But I found many data are not accurate.
Researchers are misplaced with wrong institutes.
Researchers with the same name are placed as one.
Cited references are not right and thus citation/H-index are not right.
Many researchers are not even PIs - they should not be ranked because they are not independent.
Some researchers died many years ago - their names should be removed.
Ranking for researchers with the same paper number and H-index is not reasonable - they should tie or be ranked according to certain good standard.
Research papers are not updated after 2011 and I found it difficult to upload the pdf documents.
Please solve these problems and your website will be very powerful one for scientific evaluation.
