Fans and critics of Bollywood -- the popular name for a $2.1 billion film industry centered in Mumbai, India -- might have some inkling of all this, particularly as movies often reflect changes in the culture. But these insights came via an automated computer analysis designed by Carnegie Mellon University computer scientists.

The researchers, led by Kunal Khadilkar and Ashiqur R. KhudaBukhsh of CMU's Language Technologies Institute (LTI), gathered 100 Bollywood movies from each of the past seven decades along with 100 of the top-grossing Hollywood moves from the same periods. They then used statistical language models to analyze subtitles of those 1,400 films for gender and social biases, looking for such factors as what words are closely associated with each other.
