Leveraging Text-to-Text Transfer Transformer (T5) for Automatic Keyphrase Generation and Filtering

This paper presents a keyphrase generation model based on the Text-to-Text Transfer Transformer (T5) architecture, which can generate keyphrases that adequately define a document's content, including those not present in the original text. The authors also introduce a novel keyphrase filtering technique based on the T5 architecture to eliminate irrelevant keyphrases.
