Mine on my relatively fresh f20 install started doing that too... knowing 
it's contents were relatively small/nil, I just stopped nepomuk, rm -rf 
~/.kde/share/apps/nepomuk/ , started nepomuk fresh

Before clearing it, I did see a *lot* of errors logged to 
.kde/share/apps/nepomuk/repository/main/data/virtuosobackend/soprano-
virtuoso.log, repeating this a bunch:

and some:
