Do You Write Like a Man or a Woman?
Found via a post at Forward Motion, my online writing community (where I've been merely lurking for way too long now:)
Copy and paste a block of text into the box. Indicate whether it's fiction, non-fiction or a blog entry (although commenters at FM have experimented and found no difference in scoring depending on which is chosen) and then click "submit." There's a note that it works best on selections greater than 500 words.
You end up with numeric male and female scores based on what they consider masculine and feminine key words (different in different languages) along with a color coded version of your text with the key words highlighted. The Genie makes its male/female guess on whichever score is higher, but it's also interesting to compare passages with larger or smaller spreads between the two scores.
Evaluating its accuracy (ie, the rate at which it correctly identifies the gender of a particular piece's author) I leave as an exercise for the amusement of others. For what it's worth, I think writing in such a way as to equalize the M/F scores would be an interesting goal.
