Plan and generate: Explicit and implicit variational augmentation for multi-document summarization of scientific articles

Multi-Document Summarization of Scientific articles (MDSS) is a challenging task that aims to generate concise and informative summaries for multiple scientific articles on a particular topic. However, despite recent advances in abstractive models for MDSS, grammatical correctness and contextual coherence remain challenging issues. In this paper, we introduce EDITSum, a novel abstractive MDSS model that leverages sentence-level planning to guide summary generation. Our model incorporates neural topic model information as explicit guidance and sequential latent variables information as implicit guidance under a variational framework. We propose a hierarchical decoding strategy that generates the sentence-level planning by a sentence decoder and then generates the final summary conditioned on the planning by a word decoder. Experimental results show that our model outperforms previous state-of-the-art models by a significant margin on ROUGE-1 and ROUGE-L metrics. Ablation studies demonstrate the effectiveness of the individual modules proposed in our model, and human evaluations provide strong evidence that our model generates more coherent and error-free summaries. Our work highlights the importance of high-level planning in addressing intra-sentence errors and inter-sentence incoherence issues in MDSS.     

韩愈故里问题研究综述及相关思考

由于史书记载不一,关于韩愈故里学界一直存有争议。流行的看法主要有四种：＂昌黎说＂、＂邓州南阳说＂、＂孟县说＂和＂修武说＂。从目前研究现状来看,支持＂孟县说＂和＂修武说＂者较多。故里之争背后是经济利益的博弈,文化搭台、经济唱戏,这本无可厚非,自有其合理性和积极作用;只是,文化搭台的前提要尊重历史,不能局限于地域之争。历史研究要跨越地域观念,以求实求真为原则。

试论乐府诗曲名与本事之关系

曲名与本事均为乐府诗的基本构成要素,二者有着非常紧密的内在联系。乐府诗本事是其曲名取义的直接来源,曲名是其本事内容的关键字眼,也是对其本事最精当的概括。文人创作往往以曲名来化用乐曲创调本事、传播本事中的各种信息,从而丰富作品的文学内涵。

The Influence of Medical Orientation on Perceived Physician Credibility

This study assessed whether two medical orientations of physicians—biomedical vs biopsychosocial—influenced individuals’ perceptions of physician credibility. Participants read a vignette describing a physician communicating either a predominantly biomedical or a predominantly biopsychosocial orientation and then completed the Measure of Source Credibility in reference to the physician. Results indicate that physicians who display a biopsychosocial orientation were rated higher in perceived competence, character, and caring. Future researchers should address various effects of the medical context on physician credibility and how patients’ preferences regarding physicians’ medical orientation influence choice of and communication with physicians, patient satisfaction, and compliance.

Using query expansion in graph-based approach for query-focused multi-document summarization

This paper presents a novel query expansion method, which is combined in the graph-based algorithm for query-focused multi-document summarization, so as to resolve the problem of information limit in the original query. Our approach makes use of both the sentence-to-sentence relations and the sentence-to-word relations to select the query biased informative words from the document set and use them as query expansions to improve the sentence ranking result. Compared to previous query expansion approaches, our approach can capture more relevant information with less noise. We performed experiments on the data of document understanding conference (DUC) 2005 and DUC 2006, and the evaluation results show that the proposed query expansion method can significantly improve the system performance and make our system comparable to the state-of-the-art systems.
