The summarization architecture proposed for the FNS 2020 shared task is based on a three-phases process.
- Preprocessing step: clean input financial reports and annotate its content at sentence level.
- Training step: deep learning models are fine-tuned for the regression task exploiting the annotations obtained during the preprocessing step.
- Evaluation phase: is applied at document level. The sentences of each annual reports make a forward pass through the fine-tuned model to obtain the estimated relevance score. The final summary merges sentences according to the relevance score predicted by the fine-tuned architecture.
