Possible change in WOS-data around 2004?

Dear all
In some of our various bibliometric studies at Karolinska Institutet, based solely on WoS-data, there seems to be a change in different trends originating around 2004 . We think that there may be some data policy change or some addition to WoS, but we cannot find it in any documentation.

Do you know of anything that has affected the contents of WoS  specifically around 2004-2005?
Best regards
