We can filter LinkedIn profiles to capture the Brazilian Diaspora in Greater Boston�
Brazilian profiles using name recognition (Namsor) of Portuguese names with Brazilian origin
Use city and university keyword filters (e.g., “São Paulo”, “Universidade Federal”) to capture additional Brazilian profiles.
Remove profiles from other Portuguese-speaking countries (e.g., Cabo Verde, Portugal) that might have been misidentified as Brazilian

To capture the “Scientific” aspect of the diaspora, we will use additional filters in Claro.
For a highest-constrained sample, we will use the “degree” filter to search for people with doctorate degrees (PhD and MD).
To cast a wider net, we will use the industry filter for scientific industries as a catch-all for the larger scientific diaspora:
Hospital & Health Care | Pharmaceuticals |
Higher Education | Medical Practice |
Research | Civil Engineering |
Computer Software | Medical Devices |
Biotechnology | Environmental Services |

What is Claro?
A powerful labor market intelligence platform that aggregates data from various sources such as LinkedIn and job boards to provide real-time insights into employment trends.
How it works:
Data Aggregation: Collects professional profile data across platforms (e.g., LinkedIn).
Filters and Custom Queries: Allows advanced searches based on job titles, industries, degrees, skills, and location. Users can create targeted queries to analyze specific workforce segments.
RESEARCH DIVISION
City of Boston
What is NamSor?
A name analysis tool that uses algorithms to infer diaspora, country of origin, and gender from personal names.
How it works:
Diaspora: The algorithm matches names to global ethnic groups based on linguistic and cultural patterns.
Country of Origin: It predicts the likely country of origin for a name, using databases of names from around the world.
RESEARCH DIVISION
City of Boston
NamSor Algorithm Accuracy and Limitations
Diaspora: Identifies Lusophone names with 85%-95% accuracy, including Brazilian, Portuguese, Luso-Asian, and Luso-African origins.
Country of Origin: Differentiates Lusophone diasporic groups with ~75% accuracy (e.g., Portugal, Brazil, Angola, Mozambique, Cape Verde).
RESEARCH DIVISION
City of Boston
Visualizing the NamSor algorithm
NamSor uses a natural language processing (NLP) model, embedding a representation of a word as real-valued vectors that encodes the meaning of the word in such a way that the words that are closer in the vector space are expected to be similar in meaning.
Names that are closer in the vector space belong to the same gender/geographic/linguistic/racial/ethno-cultural group.
RESEARCH DIVISION
City of Boston
Easy case: distinct ethnic groups
Russian, Nigerian, Turkish, Japanese and Polish names are quite distinctive.
Russian
Nigerian
Turkish
Japanese
Polish
RESEARCH DIVISION
City of Boston
Hard case: Portuguese-speaking diasporic groups are harder to differentiate
French, Portuguese, Italian, Spanish names belong to the same linguistic group, have had significant cross-migration and cultural exchanges.
Portuguese (from Portugal) and Brazilian Portuguese name are hard to differentiate (current model accuracy is ~75%).
