Determine the gender of a name

Namsor's name checking tool can help you determine if a name is more likely to be male or female. We offer many possibilities of treatments for gender name determination: you can provide a first name, an unsplit full name or a first and last name combination, and improve the accuracy by adding a local context (country of residence). Our technology also supports Chinese and Japanese names, and a large number of alphabets*.

Genderize a first or split name: Determines the gender from a first name or a combination of a first name and a last name. Accuracy can be improved by adding a country of residence.
Genderize an unsplit full name: Determines the gender from a full name. Useful if unable to identify the structure of a name (first name/last name). Accuracy can be improved by adding a country of residence.
Genderize a Japanese name: Determines with greater precision the gender of a Japanese first name or a Japanese full name written in Latin alphabet or in Japanese characters (Kanji).
Genderize a Chinese name: Determines with greater precision the gender of a Chinese first name or a Chinese full name written in Latin alphabet (Pinyin) or in standard Mandarin Chinese.

What is the gender of a name

The gender is defined as a set of characteristics considered to relate to femininity and masculinity. Depending on some contexts, this may include social structures based on gender identity and sex. Most cultures use a gender binary, in which gender is divided into two categories: boys/men/male and girls/women/female.

The gender estimated from a name is not absolute, so we indicate the probability that the identified gender is correct. Adding a surname and/or country of residence significantly increases accuracy. If the probability of the returned gender is between 45% and 55%, the name can be interpreted as being a unisex name.

For example, the name Keith Haring is identified as a male name with a probability of 90.63%.

If the first and last names are clearly identifiable, the Genderize Japanese Name feature (FIRST & LAST NAME) will be slightly more accurate.

What is the gender of a Japanese name in Kanji or romanized

The gender of a Japanese name written in Kanji or in Latin is a binary classification of gender: masculine or feminine. In addition to being identified as masculine or feminine, a name can be qualified as unisex or gender neutral if the probability of the returned gender is close to 50%.

Kanji are the adopted logographic Japanese characters that are used in the Japanese writing system. Kanji is one of the three writing systems that are more commonly know as Japanese characters.

Romanization is the conversion, to the Latin alphabet, of any other writing system.

For example, the Japanese first name 中松 and last name 義郎 written in Kanji, is identified as a male name with a probability of 55.01%.

From a Chinese name estimate the most likely gender

Analyzes a Chinese first name and optional last name, or an unsplit Chinese full name, in standard Mandarin Chinese or in Latin alphabet (Pinyin), to identify the most likely gender with higher accuracy. If the first and last names are clearly identifiable, the Genderize Chinese Name feature (FIRST & LAST NAME) will be slightly more accurate.

The Genderize Chinese Full Name feature will only work with Chinese full names written in standard Mandarin Chinese.

Genderize Chinese Name

Tag: Genderize Chinese Name.
Precision:
Cost: 1 credit per name.
API: Genderize Chinese Name documentation.
Determine: the most likely gender with a calibrated probability for the returned gender.

What is the gender of a Chinese name in standard Mandarin or Pinyin

Standard Mandarin Chinese is the official language of China. It uses a logographic system called Hanzi that is more commonly know as Chinese characters.

Pinyin is the official romanization system for Standard Mandarin Chinese. It is used to depict Mandarin logograms with the Latin alphabet, used by languages such as English.

The gender of a Chinese name written in standard Mandarin or in Pinyin is a binary classification of gender: masculine or feminine. If the probability of the returned gender is between 45% and 55%, the name can be interpreted as being a gender neutral name.

For example, the Chinese full name written in standar Mandarin Chinese 谢晓亮 is identified as a male name with a probability of 53.29% and can therefore be considered a unisex name because it is worn by almost as many men as women.
