Name gender: gender from a name

The name gender feature analyzes a name to identify :

  • the most likely gender ;
  • the character set used for analysis ;
  • a calibrated probability for the returned gender.

Our artificial intelligence is based on the morphology of names to identify the most likely gender of a name. We can identify the gender of a first name, the gender of a full name or the gender of a nickname. The gender determined from a full name will benefit from a more precise result than the gender determined from a first name.
Our taxonomy includes two gender: male or female. A probability between 45% and 55% indicates that it is a unisex name with a male name or female name tendency.

About name gender determination

What is the gender of a name

Gender is the range of characteristics pertaining to femininity and masculinity. Depending on the context, this may include sex-based social structures and gender identity. Most cultures use a gender binary, in which gender is divided into two categories: boys/men/male and girls/women/female.

For example, the full name Rosalind Franklin is identified as being a female name with a probability of 98.65%. Although we identify a gender (male/female) for names with a probability between 45% and 55%, these names can be considered as unisex names.
