Namsor applies onomastics, the science of names - to map diasporas globally and produce migration data from the "big data"; who are they, where are they, what are they doing. We help countries and organizations reach out to diasporas, for economic development, brain gain and innovative projects. We've doing diaspora mappings and engagement projects on all continents, since 2014. Our state-of-the-art maching learning algorithms are compliant with GDPR and IA ACT. We also build Machine Learning/AI technology to measure biases in algorithms, with respect to gender, race/ethnicity or country of origin.
