“才怪”的词汇化及语用功能     

丁婵婵 《池州学院学报》2014,(5)

"才怪"在现代汉语口语中十分常见,通过分析"才怪"的句法语义表现,可以拟测其词汇化过程并探讨其词汇化机制。我们初步推测"才怪"是由"才+奇怪"演化并词汇化。"才怪"作为后置标记,表达反预期信息,具有否定功能。"才怪"具有特殊的否定语用价值,在使用上有一定的制约条件。  相似文献

学术论文网络首发的困境及其解决路径——基于中国知网学术期刊网络首发出版发布系统的分析     

唐虹  朱银周 《中国科技期刊研究》2022,33(9):1225

【目的】 探讨学术论文网络首发中存在的困境,并提出解决路径,为期刊编辑部提供参考。【方法】 在与传统出版流程对比的基础上,以中国知网学术期刊网络首发出版发布系统为研究对象,从期刊编辑部、作者、网络出版商和期刊管理部门的角度,分析学术论文网络首发过程中存在的困境,并寻找解决困境的方法。【结果】 学术论文网络首发的困境主要体现在:网络出版商、期刊编辑部和作者三者之间的利益之争,网络出版权及其利益的高度垄断制约着期刊的发展;期刊管理政策与网络首发的内在要求之间的不匹配;现代期刊编辑角色转型带来的编辑角色失调;首发论文的校对标准之争;网络首发论文的认证、引用、评价和撤稿问题;网络首发可能导致论文多个版本共存,容易引起阅读障碍;纸刊存在价值的争议。【结论】 要破解网络首发(网络出版)的困境,最终需要平衡网络出版商、编辑部和作者之间的利益;期刊编辑需要转变为全能编辑;建立基于单篇论文网络首发的期刊出版新模式;实行以网络首发或纸刊出版为最终出版模式的单轨制出版;国家改革网络首发模式下的期刊管理办法,重点监管网刊。  相似文献

Perspectives on the right to publish: Globalinequalities, digital publications, and thelegacy of revolutionary France     

William Wresch 《Ethics and Information Technology》2003,5(2):117-127

By 1789 the French Enlightenment had alreadyestablished that the rights of citizensincluded the right to speak, write, and printfreely. This right has since been enshrined invarious national and international documents,but remains elusive in much of the world. Oneway to consider these freedoms is to look notjust across the world comparing nations thathave or don't have freedom, but back throughtime at the first effort to promulgate thesenew rights – the French Revolution. When theFrench Revolution created freedom of the pressin 1789, the French book publishing industrywas noted for five attributes: completecensorship of all publications, a rigidlyenforced printing monopoly, copyrightprotection for all authors, fossilized content,and the proliferation of illegal presses. Digital technology is enabling a second dawn ofpress freedoms, but the five problems found inFrance two centuries ago can still be seen invarious forms, especially in the massivemonopoly of book publishing by a few countries. The answers created by France in 1810 present apartial basis for how current governments couldrespond to contemporary problems with freedomof the press. Rightly used, new digitaltechnology also has an opportunity to finallyfacilitate one of civilization's fundamentalfreedoms.  相似文献   

Relevance-based entity selection for ad hoc retrieval     

Faezeh Ensan  Feras Al-Obeidat 《Information processing & management》2019,56(5):1645-1666

Recent developments have shown that entity-based models that rely on information from the knowledge graph can improve document retrieval performance. However, given the non-transitive nature of relatedness between entities on the knowledge graph, the use of semantic relatedness measures can lead to topic drift. To address this issue, we propose a relevance-based model for entity selection based on pseudo-relevance feedback, which is then used to systematically expand the input query leading to improved retrieval performance. We perform our experiments on the widely used TREC Web corpora and empirically show that our proposed approach to entity selection significantly improves ad hoc document retrieval compared to strong baselines. More concretely, the contributions of this work are as follows: (1) We introduce a graphical probability model that captures dependencies between entities within the query and documents. (2) We propose an unsupervised entity selection method based on the graphical model for query entity expansion and then for ad hoc retrieval. (3) We thoroughly evaluate our method and compare it with the state-of-the-art keyword and entity based retrieval methods. We demonstrate that the proposed retrieval model shows improved performance over all the other baselines on ClueWeb09B and ClueWeb12B, two widely used Web corpora, on the [email protected], and [email protected] metrics. We also show that the proposed method is most effective on the difficult queries. In addition, We compare our proposed entity selection with a state-of-the-art entity selection technique within the context of ad hoc retrieval using a basic query expansion method and illustrate that it provides more effective retrieval for all expansion weights and different number of expansion entities.  相似文献

面向语义Web的本体学习研究     

张建文  王强 《科技广场》2006,(8):18-20

语义Web的创建需要一套共同的标准概念体系,即本体(Ontology)。本体的构造手段仍然是以手工构造为主,效率和准确率都非常低,很容易导致知识获取的瓶颈。本文给出一个半自动化的需人工干预的本体学习体系结构,采用平衡的协作建模方式来构造语义Web中的本体;介绍了基于以上体系结构的本体学习的处理过程,并讨论了领域概念抽取,概念之间关系的抽取等关键技术。  相似文献
