I'm getting familiar with data on Twitter-Insight on Blue-Mix. I have noticed that there is a added field "USER-GENDER". As this field is not in user profiles, I tried to look in the documentation but it's not mentioned how the gender is evaluated (by Surname? by previous tweets (this would probably means that a specific algorithm is used? which one?). If you can point me to any documentation that I missed that would be highly appreciated. Martin
You are probably referring to the Insights for Twitter documentation that lists gender information as an enrichment. That information can be directly obtained from the Twitter profiles, by analyzing the profile data. There are other services including Twitter itself that provide gender information based on the profile data. How the gender is derived is not documented. :)
