They are assertions. IIRC the terminology was a bit like:
statement: 'The moon is made of cheese'
assertion (... I now make a claim about the world, for example by
publishing a respective RDF triple ...): 'The moon is made of cheese'
fact: turns out to be a wrong assertion (as far as we know modulo
the moon landing conspiracy story)
Nearby: [1]. Now waiting to get beaten up by Pat and or Alan for my
naivety w.r.t. discrete math ;)
Cheers,

All the data continuously generated in your IT infrastructure contains a
definitive record of customers, application performance, security
threats, fraudulent activity and more. Splunk takes this data and makes
