This seemed interesting because I am working on visual story structure diagramming software (looking for beta users btw), but I wasn't very impressed with their results. Basically the only interesting conclusion I could see was "stories need emotional movement", e.g. there were no examples where things were happy or sad and continued at the same level throughout the events of the story. I couldn't tell if this could even identify the stories shape from their sentiment graph -- e.g. if you fed it "Cinderella" could it identify the "Rags to Riches" plot that they identify? It would be neat to see if you could extract and identify plot points -- deaths, fights, breakups, betrayals, (maybe with some of those newfangled neural network thinggies) and look for patterns there. Still, it's encouraging to see people working on this. Maybe the results seem basic because this field is still unstudied. I expect software tools for storytelling to change a lot in the coming years with all the exciting new work in natural language processing and machine learning.
