Frequently Answers and Questions about Damegender

Ethical Values

Is Damegender reducing the gender gap?

We use say Damegender can reduce the gender gap. To reduce the gender gap is an objective in United Nations, so the states must help to this objective. To reduce the gender gap we must measure where it is happening. Damegender is Free Software with data extracted from the states, so we can measure about men and women with a critical point of view that can be reviewed by peers.

Can I guess the sexual orientation with Damegender?

Not, you can’t. You only guess the gender, such as the states is registering it. All states is using a binary ideology about the gender (male and female) and in Damegender too.

Is Damegender Free Software?

Yes, it’s. We are distributing the software in Pypi with GPLv3. You can read the license in all files and the full text in LICENSE file.

Why are you guessing male or female?

Some aplications are guessing unknown, but in Damegender we are thinking that this option is ok if the name is not in database. In this case, we are providing a binary response using machine learning.

Some radical LGTB associations are claiming by non binary options about gender, that is not an option for us due to there not states acknowledging this need and providing Open Datasets about names and gender. The states are providing us the datasets.

Are you predicting ethical problems using machine learning for guess names?

Machine learning is similar than statistics, so you don’t be afraid using maths when you are coding. Damegender can be used on a laptop, so that you are not depending of a very big company as Amazon for use the machine learning.

If you introduce a word such as chair, table, etc. you could have a gender ethical problem because you are giving a gender to a thing. In Afghanistan there are women with no names referenced as things, so the problem is dangerous. You can use Damegender to understand if the person is talking about a male or a female, but you must understand that you must not self reference or reference to another people as things. Please be careful, it’s your responsability.
