At some time in the past (like a year ago?) I had to add it to my make.conf 
because some packages would not work without it, but forgot the details.  This 
is what is currently using it on my system:

$ euse -I semantic-desktop
global use flags (searching: semantic-desktop)
************************************************************
[+ C  ] semantic-desktop - Cross-KDE support for semantic search and 
information retrieval

Installed packages matching this USE flag: 
kde-base/dolphin-4.4.5
kde-base/gwenview-4.4.5-r1
kde-base/kdebase-runtime-meta-4.4.5
kde-base/kdelibs-4.4.5-r2
kde-base/kdepimlibs-4.4.5
kde-base/kdepim-meta-4.4.9
kde-base/kget-4.4.5
kde-base/plasma-workspace-4.4.5
kde-base/pykde4-4.4.5-r1
net-wireless/kbluetooth-0.4.2

local use flags (searching: semantic-desktop)
************************************************************
[+ C  ] semantic-desktop (kde-base/pykde4):
Enables Nepomuk and Soprano python language bindings

A full KDE DE may need it more than this.
