Welcome to Mapping Atlantic Portuguese Atlantic, where we explore the hidden stories within almost 170,000 official correspondence documents spanning nearly 200 years of history. To extract the most valuable insights from this treasure trove of information, we utilize advanced natural language processing methods and named-entity recognition models to enrich our dataset. Join us on this exciting journey as we unlock the secrets of the past and shed new light on the history of the Portuguese empire in the Atlantic world.
We developed a digital method for converting archival data into network data, which involved creating a random sample, annotating entries, training a NER model, using regular expressions to identify text patterns and metadata, and conducting network analysis. This enabled us to analyze administrative correspondence more effectively and construct a structured network format.
Our study uses natural language processing and network science to analyze communication patterns of imperial commoners in Rio de Janeiro, Salvador da Bahia, and Luanda. We aim to reveal macro-level political changes and how non-elite groups shaped the policies of Brazilian and West African colonial spaces, uncovering hidden stories of the Portuguese Empire's common people.
We are a multidisciplinary team dedicated to conducting an integral research project that relies on mixed methods analysis. The project consists of two research lines: Digital Humanities with computational methods and Historical Research. The team will work simultaneously on both lines of research, as they are interdependent and must be conducted in an integral manner.
Our digital history publications on the Portuguese Empire offer significant contributions to the field, providing insightful analysis and interpretation of this captivating period. We invite you to explore our works and expand your knowledge.
