Webscriptions, CTL-DRP captures semantic information of relation labels. With prompts, CTL-DRP adds connections between en-tities and descriptions. These features make original sentence embeddings become entity-relation-aware. Furthermore, CTL-DRP generates candidate relations, and ranks the relations based on contrastive learning in a unified … WebSlightly deviating from the usual approach, we define the CTL semantics using a mapping VCTL that maps a state/path and a CTL formula to a truth value in B= {0,1}. Also, some of our definitions are non-standard in order to be closer to the robust semantics introduced later. However, let us stress that the definition below is equivalent to ...

CTL has been extended with second-order quantification $${\displaystyle \exists p}$$ and $${\displaystyle \forall p}$$ to quantified computational tree logic (QCTL). There are two semantics: the tree semantics. We label nodes of the computation tree. QCTL* = QCTL = MSO over trees.
