We propose a new approach, based on Transformer-based encoding, to
highlight extraction. To the best of our knowledge, this is the first
attempt to use transformer architectures to address automatic highlight
generation. [SEP] Highlights are short sentences used to annotate
scientific papers. They complement the abstract content by conveying the
main result findings. To automate the process of paper annotation,
highlights extraction aims at extracting from 3 to 5 paper sentences via
supervised learning. Existing approaches rely on ad hoc linguistic
features, which depend on the analyzed context, and apply recurrent neural
networks, which are not effective in learning long-range text
dependencies. This paper leverages the attention mechanism adopted in
transformer models to improve the accuracy of sentence relevance
estimation. Unlike existing approaches, it relies on the end-to-end
training of a deep regression model. To attend patterns relevant to
highlights content it also enriches sentence encodings with a
section-level contextualization. The experimental results, achieved on
three different benchmark datasets, show that the designed architecture is
able to achieve significant performance improvements compared to the
state-of-the-art.

We design a context-aware sentence-level regressor, in which the semantic
similarity between candidate sentences and highlights is estimated by also
attending the contextual knowledge provided by the other paper sections.

Fig. 2, Fig. 3, Fig. 4 show the effect of varying the number K of selected
highlights on the extraction performance. As expected, recall values
increase while increasing the number of selected highlights, whereas
precision values show an opposite trend. [SEP] Highlights are short
