verBERT: Automating Brazilian Case Law Document Multi-label Categorization Using BERT
This work addresses the need for efficient document categorization in the Brazilian legal domain, but it is incremental as it applies an existing method (BERT) to a new dataset.
The paper tackled the problem of automating multi-label categorization of Brazilian case law documents using BERT, achieving an F1-micro score of 0.72, which represents a 30 percentage point improvement over a statistical baseline.
In this work, we carried out a study about the use of attention-based algorithms to automate the categorization of Brazilian case law documents. We used data from the Kollemata Project to produce two distinct datasets with adequate class systems. Then, we implemented a multi-class and multi-label version of BERT and fine-tuned different BERT models with the produced datasets. We evaluated several metrics, adopting the micro-averaged F1-Score as our main metric for which we obtained a performance value of F1-micro=0.72 corresponding to gains of 30 percent points over the tested statistical baseline.
