We are all aware that gender can influence many aspects of our lives (nurture/nature/sociology is beside the point for the moment) including how we walk, colours we are drawn to, and some would argue the way we throw balls.
There is also a website that claims it can determine the gender of your writing from your word usage. For example the song writing of Axel Rose was deemed have a female structure of word usage.
Here is a little bit more about it:
In 2003, a team of researchers from the Illinois Institute of Technology and Bar-Ilan University in Israel (Shlomo Argamon, Moshe Koppel, Jonathan Fine, and Anat Rachel Shimoni) developed a method to estimate gender from word usage. Their paper described a Bayesian network where weighted word frequencies and parts of speech could be used to estimate the gender of an author. Their approach made a distinction between fiction and non-fiction writing styles.To check out the gender of your own writing using the Gender Genie, click here
