谈谈如何讲授邓小平哲学理论的基本特征问题     

朱荣英 《忻州师范学院学报》2004,20(5):52-56,59

当前无论学届的理论研讨抑或“两课”的教学实践，皆因偏离有中国特色社会主义建设的实践，将考察邓小平哲学理论基本特征的参照系误置，从而产生诸多认识误区；并以马克思主义哲学与当代中国实践相契合为理论支点，在廓清各种认识误区的同时，闸明了如何讲授邓小平哲学理论四个基本特征(实践性、真理性、超越性和总括性)所应注意的理论问题和具体要求；从世界观高度表征了马克思主义哲学理论“与时促进的理论品质”和逐步中国化的必然走势；按“三个代表”的总体要求，凸现了邓小平哲学理论是马克思主义哲学中国化的新形态，代表了当代中国先进文化(尤其是哲学发展的)前进方向。  相似文献   

Summarizing Similarities and Differences Among Related Documents   总被引：10，自引：0，他引：10  

Inderjeet Mani  Eric Bloedorn 《Information Retrieval》1999,1(1-2):35-67

In many modern information retrieval applications, a common problem which arises is the existence of multiple documents covering similar information, as in the case of multiple news stories about an event or a sequence of events. A particular challenge for text summarization is to be able to summarize the similarities and differences in information content among these documents. The approach described here exploits the results of recent progress in information extraction to represent salient units of text and their relationships. By exploiting meaningful relations between units based on an analysis of text cohesion and the context in which the comparison is desired, the summarizer can pinpoint similarities and differences, and align text segments. In evaluation experiments, these techniques for exploiting cohesion relations result in summaries which (i) help users more quickly complete a retrieval task (ii) result in improved alignment accuracy over baselines, and (iii) improve identification of topic-relevant similarities and differences.  相似文献   

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

《Information processing & management》2023,60(4):103409

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.  相似文献

韩愈故里问题研究综述及相关思考     

苏全有  李玉莉 《焦作大学学报》2009,23(1):24-27

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。  相似文献

试论乐府诗曲名与本事之关系     

向回 《石家庄学院学报》2012,14(4):51-54

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。  相似文献
