Abstractive Text Summarization is the task of generating a short and concise summary that captures the salient ideas of the source text. https://doi.org/10.1016/j.neunet.2019.12.022. However, the level of actual abstraction as measured by novel phrases that do not appear in the source document remains low in existing approaches. A Model for Abstractive Text Summarization Audio version of the article Students are often tasked with reading a document and producing a summary (for example, a book report) to demonstrate both reading comprehension and writing ability. With only 1000 fine-tuning examples, we were able to perform better in most tasks than a strong baseline (Transformer encoder-decoder) that used the full supervised data, which in some cases had many orders of magnitude more examples. Sometimes even no specific datasets are necessary. Necessary cookies are absolutely essential for the website to function properly. By continuing you agree to the use of cookies. Yet I have the feeling that the version of the model, which I have tested is not yet there in terms of delivering results, that are always meaningful and correct. The dotted-line shows the Transformer encoder-decoder performance with full-supervision, but without pre-training. In “PEGASUS: Pre-training with Extracted Gap-sentences for Abstractive Summarization” (to appear at the 2020 International Conference on Machine Learning), we designed a pre-training self-supervised objective (called gap-sentence generation) for Transformer encoder-decoder models to improve fine-tuning performance on abstractive summarization, achieving state-of-the-art results on 12 diverse summarization datasets. Could I lean on Natural Lan… ∙ Virginia Polytechnic Institute and State University ∙ 8 ∙ share . Here we will be using the seq2seq model to generate a summary text from an original text. Conclusion. We evaluate our proposed model using an Introduction-Abstract summarization dataset from scientific articles and the CNN/Daily Mail summarization benchmark dataset. Many abstractive summarization models use attention mechanisms, making them unsuitable for long texts. Models. The temporal hierarchical network is implemented with a multiple timescale architecture where the timescale of each layer is also learned during the training process through error backpropagation through time. 12/05/2018 ∙ by Tian Shi, et al. Neural Abstractive Text Summarization with Sequence-to-Sequence Models. Further, we observe that RL-based models are becoming increasingly ubiquitous for many text summarization tasks. Fun Fact: The model has achieved better results than its peer models like T5 while using only 5% of the number of parameters of T5. PEGASUS code and model release While PEGASUS showed remarkable performance with large datasets, we were surprised to learn that the model didn’t require a large number of examples for fine-tuning to get near state-of-the-art performance: ROUGE scores (three variants, higher is better) vs. the number of supervised examples across four selected summarization datasets. In prior work, the self-supervised objectives used in pre-training have been somewhat agnostic to the down-stream application in favor of generality; we wondered whether better performance could be achieved if the self-supervised objective more closely mirrored the final task. In this paper, we introduce a temporal hierarchical pointer generator network that can represent multiple compositionalities in order to handle longer sequences of texts with a deep structure.
