Mechanisms, in a natural language processing (NLP) system comprising a processor and a memory, are provided. The NLP system receives information for identifying a plurality of audience members of an audience for an upcoming performance and retrieves personality trait information for the plurality of audience members from one or more personality trait information sources. The NLP system generates an aggregate audience model based on the personality trait information for the plurality of audience members. The aggregate audience model specifies an aggregate personality trait of the audience. The NLP system modifies a portion of the performance to tailor the performance to the aggregate personality trait of the audience as specified in the aggregate audience model.
