• Title: Cross-Domain Robustness of Transformer-based Keyphrase Generation
• Authors: Anna Glazkova and Dmitry Morozov
• Abstract summary: A list of keyphrases is an important element of a text in databases and repositories of electronic documents. In our experiments, abstractive text summarization models fine-tuned for keyphrase generation show quite high results for a target text corpus. We present an evaluation of the fine-tuned BART models for the keyphrase selection task across six benchmark corpora.

• Abstract: Modern models for text generation show state-of-the-art results in many natural language processing tasks. In this work, we explore the effectiveness of abstractive text summarization models for keyphrase selection. A list of keyphrases is an important element of a text in databases and repositories of electronic documents. In our experiments, abstractive text summarization models fine-tuned for keyphrase generation show quite high results for a target text corpus. However, in most cases, the zero-shot performance on other corpora and domains is significantly lower. We investigate cross-domain limitations of abstractive text summarization models for keyphrase generation. We present an evaluation of the fine-tuned BART models for the keyphrase selection task across six benchmark corpora for keyphrase extraction including scientific texts from two domains and news texts. We explore the role of transfer learning between different domains to improve the BART model performance on small text corpora. Our experiments show that preliminary fine-tuning on out-of-domain corpora can be effective under conditions of a limited number of samples.

  Keyphrases are crucial for searching and systematizing scholarly documents. In this paper, we experiment with popular transformer-based models for abstractive text summarization. We show that summarization models are quite effective in generating keyphrases in the terms of the full-match F1-score and BERT.Score. We also investigate several ordering strategies to target keyphrases.

• Keyphrase Generation Beyond the Boundaries of Title and Abstract [28.56508031460787]
  Keyphrase generation aims at generating phrases (keyphrases) that best describe a given document. In this work, we explore whether the integration of additional data from semantically similar articles or from the full text of the given article can be helpful for a neural keyphrase generation model. We discover that adding sentences from the full text particularly in the form of summary of the article can significantly improve the generation of both types of keyphrases.

  Large-scale language models (LMs) pretrained on massive corpora of text, such as GPT-2, are powerful open-domain text generators. It is still challenging for such models to generate coherent long passages of text, especially when the models are fine-tuned to the target domain on a small corpus. We propose a simple but effective method of generating text in a progressive manner, inspired by generating images from low to high resolution.
