What can namsor estimate from a name?

Analyze names to estimate gender, cultural origins, and ethnicities. Determine likely country of residence and religious background. For Indian names, identify caste groups. Classify name types (personal, place, alias) and transliterate between writing systems. Parse and format full names and much more.

All the information that Namsor can estimate from a name.

How namsor estimate origin and gender from names?

Experts in natural language processing (NLP) for over 10 years, we have developed an AI specialized in onomastics - the scientific study of proper names. This expertise is built on deep morphological analysis of name structures and patterns across cultures.

Example of a basic morphological analysis of the Sharma surname.
Natural Language Processing
A branch of AI that combines linguistics and computer science to help machines understand, interpret, and generate human language.
Onomastics
The scientific study of names, focusing on their origin, meaning, history, and usage across different cultures and languages.
Morphological name analysis
The analysis of the internal structure of names—such as prefixes, suffixes, and roots—to uncover their linguistic origin and cultural significance.

At Namsor, we use these principles through artificial intelligence specialising in the analysis of proper nouns. It accurately identifies gender and ethnic backgrounds based on name structure. This tool is essential for researchers, businesses, and organizations requiring precise onomastic intelligence.

Is Namsor the best tool for analysing names?

Namsor's specialized onomastics stands out when compared to LLMs, databases, and other name analysis tools.
