swapUNIBA@FinTOC2022: Fine-tuning Pre-trained Document Image Analysis Model for Title Detection on the Financial Domain

no code implementations • FNP (LREC) 2022 • Pierluigi Cassotti, Cataldo Musto, Marco DeGemmis, Georgios Lekkas, Giovanni Semeraro

We address the task using a two-stage process: first, we detect titles using Document Image Analysis, then we train a supervised model for the hierarchical level prediction.
