8 On the other hand, the σ e k score weights the salience of the unified event e k by combining the weights of e i and e j into a new weight assigned to e k .
in this work, we compute activation of an event e simply by summing the activation scores of the single lexical items cuing it (i.e., the conditional probabilities of the event given each lexical item in the input sentence): the score σ e k measures the degree to which the unified event is activated by the linguistic expressions composing it.
