Recently, I’ve read not one but two articles on using algorithms to predict the success of movies. In both cases, the analysts start with a script (one team uses human analysts, the other a computer), then analyze it for key elements, plot twists, setting, characters, and so on. Then they use what appears to be regression analysis to determine the degree of commonality the script has with other hits.
And it works. Hits show up. Misses are clearly seen.
