We design a self-decision goal-oriented multiple access scheme, where sensing agents observe a common event and individually decide to communicate the event's attributes to the monitoring agents, to satisfy a certain goal. Decisions are based on the usefulness of contents, which are generated under uniform, change- and semantics-aware content acquisition, as well as statistics and contents of other agents. We obtain optimal activation probabilities and threshold criteria for decision-making under all schemes, maximizing a grade of effectiveness metric. Combined with a semantics-aware acquisition scheme, the self-decision scheme offers, on average, 29.52% higher effectiveness, 25.13% fewer drop-offs, and 67.21% fewer transmissions.
