Modeling Uncertainty in PROV - presented at WWW2013

Hi all,

since we're sharing PROV stories, I thought I'd let you know of our recent
contribution at WWW2013 [1].

It's a very simple & lightweight set of attributes, used to model
provenance in case the content is uncertain, or when the provenance
statements are uncertain themselves.
I needed these for my work with Named Entity Recognition, provenance
reconstruction and trust assessment, and decided to write a short paper
about them in case someone else had use for them. Since most PROV
statements support attributes, the PROV I add these to remains perfectly
valid.
Of course, you could create your own attributes for this, but should you
want to use them as well, we've created an "UP" namespace at our lab's
website [2].

Best regards,
Tom
