At Oxford Brookes University, Carla was a visiting PhD student from Universidade Federal do Rio Grande do Sul, Brazil (from September 2017). Her thesis was about Text Mining, specifically about Topic Modeling. Carla is working with different mathematical models to represent latent relations between words and documents, aiming to improve coherence among resulting topics.
Although ‘in principle’ many models have been developed for the task of finding topics in a set of documents, it still too hard to use the results ‘in practice’ for decision-making process inside organizations. To better understand these models, working with real-world data can contribute to the use of (the fast-growing) text data, applying data science towards business value and performance.
Carla is now a professor at the Federal University of Uberlândia, Brazil.
