New specialized pre-training objectives for language models learn rich representations of keyphrases directly from text, achieving state-of-the-art performance for both keyphrase extraction and generation. These keyphrase-aware models also demonstrate competitive or improved results on various general NLP tasks, including named entity recognition, question answering, and abstractive summarization.
Key insights
- Explicitly tailoring pre-training objectives to keyphrase understanding significantly boosts performance on keyphrase extraction and generation tasks, validating the benefits of task-specific pre-training.
- Learning rich keyphrase representations generalizes well to other fundamental NLP tasks, suggesting keyphrase identification is a foundational capability that enhances broader language understanding.
- High-quality, author-tagged keyphrases are critical for successful large-scale language model pre-training, outperforming noisy or automatically derived keyphrases.
