I am looking for a pre-trained model for abstract summarization, I have used the Google Pegasus-xsum and Pegasus-Large, the xsum seems good but only provide one liner summary, while the Pegasus-large seems that it is providing the extractive summary rather than the abstractive, it just picks up the sentences from paragraph and shows it as summary. Can anybody provide the best abstract summary model for common sentences, I don’t need for any specific domain, just common day to day usage paragraphs.
