"Since the summer of 2013, UI Assistant Professor of business Kang Zhao and UI graduate student Michael Lash* have tried to find a reliable way to predict the profitability of film releases. Their shared interests in movies and big data inspired them to develop a unique way for determining box-office success. [...]

'This is a nice example of data-mining computer science,' [Street] said, 'People working on specific business-related problems in a way other people don’t know how to predict.' Because manually copying and pasting data from thousands of movies would be impossible, Lash had to create a code that would automatically collect statistics. 'I built what’s called a web scraper to scrape lots of data from a site called Box Office Mojo, and later augmented that to scrape additional information from IMDB,' he said. 'We now have, I think, more than 16,000 or 17,000 movies in our data base.'

The researchers said they used an algorithm called 'random forest' to predict profitability."
