The ‘Number of Collaborated Products’ of a ‘Co-Researcher’ is less than the number of research products listed as co-authors in ‘Research Products’.

The ‘Number of Collaborated Products’ in a ‘Researcher Details’ page is created by an automated counting of co-authors and only when the corresponding ‘Researcher Number’ can be identified.
In such cases as below, authors can not be identified by an automated counting and thus may not be included in ‘Number of Collaborated Products’:

  • The research product involves multiple researchers with the same surname, and the surname is listed as the author and so on
  • Papers written in English whose researcher’s name does not appear in the Roman alphabet in reports and other documents on the KAKEN Database

We would appreciate your understanding.
