These datasets contain complete genre, cast, director, and producer information about 15,425 U.S.-produced movies released between 1894 and 2011.The initial movie year, title, and genre information was obtained by Wasserman et al. (Cross-evaluation of metrics to estimate the significance of creative works, PNAS, 2015) from IMDb.com That dataset was expanded by Moreira et al. (forthcoming, 2017) to include movie budget, gender composition, cast, director, and producer information.Assigning gender to individualsThe gender of actors is explicitly mentioned in their individual biographical pages, thus we are able to fully determine their gender. For producers and directors that do not also have acting credits, we use indirect methods to assign a gender. If present, we parse the individual's biographical text for gender-specific pronouns (he/his/him/himself, or she/her/hers/herself). If the number of (male-) female-specific pronouns exceeds that of (female-) male-specific ones, we assume the individual is a (male) female. If the previous attempt is inconclusive, we use the Python package gender-guesser (version 0.4.0) to "guess" the gender based on the first name of the individual. The output of gender-guesser is one of "female", "mostly female", "androgynous", "unknown", "mostly male", or "male". We only assign a gender if the guess is either "male" or "female". If we still have not been able to assign a gender, we try to find a photograph of the individual. If all attempts fail, we mark the individual's gender as "undetermined".actors.json - Contains the following information about 225,754 actors:_id - unique IMDb identifier of individual.name - individual's namegender - individual's genremovies_list - list of movie ids individual was cast in.
