In accordance with the information there, the anchor of an epistemic state introduced by the SIP be aware (which behaves like the SIP know) in a context of factuality PS− is characterized with a factuality stance of certainty (CT+), whereas the cognizer, being unaware, remains uncommitted (Uu) (Step 5).
because there are no other factuality markers affecting these values, when the parser reaches event e 2 (Joe knowing something) these are the factuality assignments constituting the factuality profile of that event: the factuality of every event corresponds to the factuality information available at its context, as computed from the interaction of the different factuality markers scoping over it.
