Query: Revenue Prediction of Local Event using Mathematical Model of Hit
  Phenomena   Theoretical approach to investigate human-human interaction in society
performed using a many-body theory including human-human interaction. The
advertisement is treated as an external force. The word of mouth (WOM) effect
is included as a two-body interaction between humans. The rumor effect is
included as a three-body interaction between humans. The parameters to define
the strength of human interactions are assumed to be constant values. The
calculated result explained well the two local events "Mizuki-Shigeru Road in
Sakaiminato" and "the sculpture festival at Tottori" in Japan.
