Example of Stanford representation. Event structures for the text fragment "... tax, acts as a costimulatory signal for GM-CSF and IL-2 gene transcription ..." (left) and the reduced form used internally in the Stanford model (right). In the reduced form, words that don't take part in any events (e.g., "for" and "and") are removed and multiword anchors are replaced with their syntactic heads (e.g., "acts as a costimulatory signal" becomes "acts").
