[en] Story plots must contain, besides physical action events, a minimal set of information-gathering events, whereby the various characters can form their beliefs on the facts of the mini-world in which the narrative takes place. Three kinds of such events will be considered here, involving, respectively, inter-character communication, perception and reasoning. Multiple discordant beliefs about the same fact are allowed, making necessary the introduction of higher-level facilities to rank them and to exclude those that violate certain constraints. Since the proposed package was designed to run in a plan-based context, other higher-level facilities are also available for pattern-matching against typicalplan libraries or previously composed plots.
