Artificial intelligence is a new ally for Brazilians seeking Portuguese citizenship. By applying a set of specific technologies and software, a group of researchers in Lisbon developed a database, which has made it possible to find historical documents and map the Portuguese migratory flow in Brazil. A fundamental step for anyone wishing to apply for nationality with the government of Portugal.
The presentation of documents from the native Portuguese, such as a birth or baptism certificate that ties him to the country, are requirements of the legislation of the European country. Research coordinator and CEO of Martins Castro, Renato Martins, says that, as the migratory process of the Portuguese began in the 15th century and was the longest in Brazilian history, many descendants know that they have Portuguese origins, but cannot locate the parent documentation.
Historian and genealogist Gabriel Dias says that the great mobility of the Portuguese generated a set of notes in the Brazilian and Portuguese public administrations, in registries, conservatories and also private records. In other words, these documents are spread across several locations in both countries. “A large part of the Portuguese arrived in Brazil without birth certificates and few with passports. Another relevant factor is that, until 1911, there was no civil registration in Portugal and births and baptisms were carried out in the parishes of the Catholic Church,” he explains.
To give you an idea, Portuguese communities estimate that there are about five million grandchildren of Lusitanians in the country, with the states with the highest number of descendants being Rio de Janeiro, São Paulo, Minas Gerais and Pará. According to Martins, there are thousands of people who can access the right, but the documentary deficit has become an obstacle when applying for Portuguese citizenship. “Thus, many know that their grandparents or great-grandparents are Portuguese and cannot have documentary evidence of the birthplace of their Portuguese ancestor”.
This social demand has motivated researchers to apply information technology to improve genealogical research and find documents when necessary. Over the last two years, Martins and his team have accumulated more than one million metadata, which have allowed them to index and cross-reference information fragments that were previously linked manually.
Dias explains that, by crossing information regarding notes and documents from the two countries, the team is able to assess and understand where the Portuguese communities are, their origins and when they were formed in different Brazilian regions. What can guarantee proof of the entry of these immigrants in Brazil and their origins in Portugal.
For Martins, these studies are allowing more visibility for Portuguese-Brazilians. “The application of technology to solve social demands impacts people's lives, who now have the right to move around the world with safety and freedom”, he believes.
