Namsor, smart data from 7.5 billion people's names

Namsor

Namsor software accurately classifies personal names by gender, country of origin or ethnicity.

Our mission is to make sense of the Big Data and help understand international flows of money, ideas and people. Our detailed, precise and specialized data mining software recognizes the linguistic or cultural origin of personal names in any alphabet/language. Names are meaningful; we use socio-linguistics to extract their semantics and deliver actionable intelligence.

We apply this innovative technology to support our clients (countries, regions, private companies and projects) in all sectors of activity. Namsor API key unlocks the value of diversity.

We support public and private diaspora marketing and engagement programs for human development and economic growth.

A name checking technology based on artificial intelligence

In order for the processing of names to be as precise and complete as possible, we have developed an artificial intelligence that is continuously maintained and enriched by our teams of data scientists, developers, historians and linguists.

Much more than a simple search on a database, our technology uses the morphology of names to estimate an origin, an ethnicity, a gender, a country of residence, the type of the name or to transcribe it. Thanks to this technology, our artificial intelligence is able to make highly accurate estimates from first names, surnames, full names, but also nicknames and invented names such as company or brand names.
