基准词是具有明确褒贬义倾向的词汇,基准词的选择对词汇倾向性判别的准确率有影响.现有的基准词选择方法主要关注的是基准词的频率、类别区分度和上下文敏感性,忽略了基准词的褒贬强度,这导致了词汇乃至更大粒度的语言单元的语义信息遗失.本文提出了一种含强度的基准词选择和词汇倾向性判别方法,首先对情感词进行语义相似性计算和聚类,然后进行倾向性计算和分类,由此得到包含语义及强度信息的基准词集,该基准词集可用于词汇褒贬性及褒贬强度的判别.我们分别使用通用搜索引擎和领域搜索引擎对该方法进行了验证,实验结果表明,领域搜索引擎下的词汇褒贬性及正负性词的褒贬强度判别准确率分别可以达到84.00%、80.49%和76.47%.  相似文献

本文基于人力资源管理中著名的“冰山理论”,对出版行业上市公司董事应具备的基准性素质与鉴别性素质进行了研究,认为作为企业董事,首先应具备财务、法律、出版行业相关专业知识等基准性素质,同时还应具备沟通协作、全局观念、勤勉尽责、独立客观等多项鉴别性素质,其中忠诚正直是其最重要的鉴别性素质.因此,在建设出版企业董事人才队伍时,一方面应以基准性和鉴别性素质要求作为选拔与培训的基础与依据,另一方面应关注个体素质的异质性,努力打造合力型、互补型的董事团队.  相似文献

根据有旋特征线理论,设计出了沿程马赫数下降规律可控的轴对称基准流场,分析了基准流场的几何参数(前缘压缩角及中心体半径)的影响规律,发现选取较小的前缘压缩角和中心体半径有利于得到性能优良的基准流场;然后在设计状态Ma=6时研究了三种典型的马赫数下降规律对这种轴对称流场性能的影响。最后考虑了粘性的影响,并进行了粘性修正探索,结果表明,采用附面层位移厚度修正方法后,基准流场的壁面压力分布和无粘情况吻合良好。   相似文献

Under pressure to fight corruption, hold public officials accountable, and build trust with citizens, many governments pursue the quest for greater transparency. They publish data about their internal operations, externalize decision-making processes, establish digital inquiry lines to public officials, and employ other forms of transparency using digital means. Despite the presence of many transparency-enhancing digital tools, putting such tools together to achieve the desired level of digital transparency, to design entire government systems for digital transparency, remains challenging. Design principles and other design guides are lacking in this area. This article aims to fill this gap. We identify a set of barriers to digital transparency in government, define 16 design principles to overcome such barriers, and evaluate these principles using three case studies from different countries. Some principles apply to projects, others to systems, yet others to entire organizations. To achieve digital transparency, before building and deploying digital solutions, government organizations should build technological and institutional foundations and use such foundations to organize themselves for transparency. The proposed design principles can help develop and apply such foundations.  相似文献

Australia's universities have seen significant growth in government research funding, with more to come, but this is not reflected in the output of research monograph publications; structural barriers stand between creation and dissemination of research. This is especially a problem for those working on Australian topics. The author has proposed a new model for funding scholarly publishing in Australia, which may well be applicable to other countries: just a small proportion of the funds committed by the Australian government to research inputs could ensure the publication of research outputs. This would deliver major gains in impact and productivity for government, universities, and individual academics alike.  相似文献

The author supports the opinion that full benefit may be derived from the technological potential on condition that serious attention is given to the social, political and ethical aspects, which are often barriers to the free and multi-directional access to information, especially in developing countries. Causes of these barriers — “disarticulations” within a society — are listed and their importance in developing countries emphasized. Possible different communication structures in a society and their effects are examined. The author concludes that the traditional, principle of free flow of information is not sufficient in the advancing information society; there is a need for a, principle which deals more specifically with the “activation”, “mediation”, and “networking” of the needs and opinions at the different levels of society.  相似文献

The lack of interagency government data sharing (IDS) has emerged as a central problem for the development of China's Internet Plus Government Services (IPGS). To identify, explain, and understand barriers to IDS in China, a total of 1495 articles were retrieved from the China Academic Journal Network Publishing Database (CAJD) and China Science Periodical Database (CSPD). After screening, 55 articles were analyzed using a thematic analysis approach. The analysis pointed at 19 barriers to IDS in four themes: External environmental barriers, interagency partnership barriers, organizational readiness barriers, and individual motivation barriers. The conceptualization of the research findings revealed five trans-barrier conceptual dimensions (political and structural, territorial, leadership, financial, and IT), from which further, more in-depth investigations should be performed. Also, the conceptualization indicated that territoriality is possibly the main barrier to China's IDS development. Territoriality offers a novel prospective for studying IDS. This research presents a robust theoretical basis for future study. Also, it provides an overview on IDS development in China and offers useful insights for similar efforts in different countries.  相似文献

传媒产业结构性进入壁垒探析   总被引:2,自引:0,他引:2  
陶喜红 《新闻界》2008,(4):10-12
规模经济、媒介产品的差异、一定的资源、必要的资金量等构成了传媒产业的结构性进入壁垒。结构性进入壁垒具有双重效应,可以维护在位媒介的利益,并形成规模效益;同时,它会排斥竞争机制、限制资源自由流动等。因此,应当辩证看待媒介产业的结构性进入壁垒。  相似文献

Summary

I describe a set of automated archives for electronic communication of research information that have been operational in many fields of physics, and some related and unrelated disciplines, starting from 1991. These archives now serve over 35,000 users worldwide from over 70 countries, and process more than 70,000 electronic transactions per day. In some fields of physics, they have already supplanted traditional research journals as conveyers of both topical and archival research information. Many of the lessons learned from these systems should carry over to other fields of scholarly publication, i.e., those wherein authors are writing not for direct financial remuneration in the form of royalties, but rather primarily to communicate information (for the advancement of knowledge, with attendant benefits to their careers and professional reputations). These archives have in addition proven equally indispensable to researchers in less-developed countries.  相似文献
