Explore the advanced features of our gender name API
Identify the most likely gender name by analyzing a first name and (optionally) a surname or an unsplit full name. Specify a local context to improve accuracy. This helps capture cultural nuances.
When you use our gender finder API or interface, you receive several indicators. Here are the main ones:
Presumed Gender (male, female) This estimate shows if the name is usually male or female.
Calibrated probability (Between 50% and 100%) This percentage shows how reliable the estimate is. If the percentage is 91% the estimated gender is very reliable. If it is 50% then it has as much chance of being male as female (common for unisex names).
Script (Latin, Cyrillic, etc.) Shows the writing system used for the name. This helps identify its linguistic and cultural roots.
What is gender, and how to infer it from a name?
Gender refers to the social or cultural classification of an individual as male or female. This classification is based on their identity, roles and expressions. Most cultures use a binary system in which gender is divided into two categories: boys/men/males and girls/women/females.
By studying names, called onomastics, we can guess a person's gender. This is done through a morphological analysis of the name.
Our gender checker API looks at the likelihood of the name being masculine or feminine. It considers cultural, linguistic, and regional differences identified during the name analysis.
If the probability of the identified gender is between 50% and 60%, it means the name is not clearly linked to one gender. This is simply because the name is used by men and women in equal proportions.
How do we determine the gender of the name?
We develop specialized AI to estimate gender. It combines morphological name analysis with advanced NLP techniques. We design each step, from assembling data sets to continuous learning, to optimize identifying male and female names.
