Atomic vs. embedding predications. Atomic and embedding predications extracted from the sentence Stimulation of cells leads to a rapid phosphorylation of IκBα, which is presumed to be important for the subsequent degradation. from the Medline abstract 7499266. The middle column in the predication rows shows the predications after the Composition phase and the right column the event and event modification annotations after the Mapping phase. Note that e2 is not mapped to an event annotation, since its argument is semantically empty, whereas em6 is not mapped since its semantic type, TEMPORAL, is not relevant in the shared task context. The relevant syntactic dependency relations as well as the entities are illustrated.
