Neural Latent Extractive Document Summarization [article]

Xingxing Zhang, Mirella Lapata, Furu Wei, Ming Zhou
2018 arXiv   pre-print
Extractive summarization models require sentence-level labels, which are usually created heuristically (e.g., with rule-based methods) given that most summarization datasets only have document-summary  ...  Since these labels might be suboptimal, we propose a latent variable extractive model where sentences are viewed as latent variables and sentences with activated variables are used to infer gold summaries  ...  Model We first introduce the neural extractive summarization model upon which our latent model is based on.  ...

Improved Document Modelling with a Neural Discourse Parser [article]

Fajri Koto, Jey Han Lau, Timothy Baldwin
2019 arXiv   pre-print
For abstractive summarization, for instance, conventional neural models simply match source documents and the summary in a latent space without explicit representation of text structure or relations.  ...  In this paper, we propose to use neural discourse representations obtained from a rhetorical structure theory (RST) parser to enhance document representations.  ...  Unlike extractive summarization, abstractive summarization has the ability to create new sentences that are not in the original document; it is closer to how humans summarize, in that it generates paraphrases  ...
