• Abstract: Recent advances in text summarization have predominantly leveraged large language models to generate concise summaries. However, language models often do not maintain long-term discourse structure, especially in news articles, where organizational flow significantly influences reader engagement. We introduce a novel approach to integrating discourse structure into summarization processes, focusing specifically on news articles across various media. We present a novel summarization dataset where news articles are summarized multiple times in different ways across different social media platforms (e.g. LinkedIn, Facebook, etc.). We develop a novel news discourse schema to describe summarization structures and a novel algorithm, DiscoSum, which employs beam search technique for structure-aware summarization, enabling the transformation of news stories to meet different stylistic and structural demands. Both human and automatic evaluation results demonstrate the efficacy of our approach in maintaining narrative fidelity and meeting structural requirements.

  We introduce a numerical narrative representation grounded in structuralist linguistic theory. We extract the actants using an open-source LLM and integrate them into a Narrative-Structured Text Embedding. We demonstrate the analytical insights of the method on the example of 5000 full-text news articles from Al Jazeera and The Washington Post on the Israel-Palestine conflict.

  We revisit a widely used conceptualization of framing from the communication sciences which explicitly captures elements of narratives.

We explore automatic multi-label prediction of our frames with supervised and semi-supervised approaches.

  Unsupervised discovery of stories with correlated news articles in real-time helps people digest massive news streams without expensive human annotations. We propose a novel thematic embedding with an off-the-shelf pretrained sentence encoder to dynamically represent articles and stories. A thorough evaluation with real news data sets demonstrates that USTORY achieves higher story discovery performances than baselines.

  Text summarization is one of the most challenging and interesting problems in NLP. This work proposes a multi-view sequence-to-sequence model by first extracting conversational structures of unstructured daily chats from different views to represent conversations. Experiments on a large-scale dialogue summarization corpus demonstrated that our methods significantly outperformed previous state-of-the-art models via both automatic evaluations and human judgment.

  We propose to explicitly incorporate the underlying structure of narratives into general unsupervised and supervised extractive summarization models. We formalize narrative structure in terms of key narrative events (turning points) and treat it as latent in order to summarize screenplays. Experimental results on the CSI corpus of TV screenplays, which we augment with scene-level summarization labels, show that latent turning points correlate with important aspects of a CSI episode.

  We introduce the Shmoop Corpus: a dataset of 231 stories paired with detailed multi-paragraph summaries for each individual chapter. From the corpus, we construct a set of common NLP tasks, including Cloze-form question answering and a simplified form of abstractive summarization. We believe that the unique structure of this corpus provides an important foothold towards making machine story comprehension more approachable.
