We want to assign each sentence a label \(y_i \in \{0, 1\}\) indicating whether the sentence should be included in the final summary[CLS] Unsupervised approaches to extractive summarization usually rely on a notion of sentence importance defined by the semantic similarity between a sentence and the document. In the era of digital explosion, which is mostly unstructured textual data, there is a demand for users to understand the huge amount of text in a short time; this demands the need for an automatic text summarizer.
