如何在海量的具有相同功能的网格服务中,为网格任务选择最合适的网格服务乃是实现服务资源优化配置的关键问题。层次分析法(AHP)是一种比较好的选择,因为它符合人的逻辑判断思维过程,能够解决多目标、多准则或无结构特性的复杂决策问题。因此本文借鉴在企业动态联盟伙伴选择机制中普遍采用的层次分析法,实现网格工作流服务资源的最优配置,从而满足用户的资源需求,达到网格服务资源的优化配置,提高网格工作流系统的性能。  相似文献

什么叫晚报(Evening Newspapers)?有人通俗地称之为“晚上看的报纸”,《现代汉语词典》上的解释是“下午出版的报纸”,《中国大百科全书》概括为“傍晚前出版的综合性城市报纸”,甘惜分主编的《新闻学大词典》则更为全面:“每天下午或傍晚发行,供人们晚饭前后阅读的报纸,是一日间发行最迟的报纸,常报道午前的消息。”[1]现在看来,“晚上看的报  相似文献

Analysis of Statistical Question Classification for Fact-Based Questions   总被引:1,自引:0,他引:1  
Question classification systems play an important role in question answering systems and can be used in a wide range of other domains. The goal of question classification is to accurately assign labels to questions based on expected answer type. Most approaches in the past have relied on matching questions against hand-crafted rules. However, rules require laborious effort to create and often suffer from being too specific. Statistical question classification methods overcome these issues by employing machine learning techniques. We empirically show that a statistical approach is robust and achieves good performance on three diverse data sets with little or no hand tuning. Furthermore, we examine the role different syntactic and semantic features have on performance. We find that semantic features tend to increase performance more than purely syntactic features. Finally, we analyze common causes of misclassification error and provide insight into ways they may be overcome.  相似文献

在学术国际化和中国哲学社会科学"走出去"的背景下,越来越多的高校对教师发表SSCI和A&HCI论文进行激励。激励制度主要体现在物质奖励和学术评价两个层面。从对国内某研究型大学文科教师深度访谈的情况来看,高校教师对人文社会科学国际发表及其激励制度持不同意见,虽一般不反对对国际发表进行物质奖励,但他们对国际发表在学术评价中的地位的认识存在较大分歧。高校在实施人文社会科学国际发表激励制度的过程中应理解和尊重差异性的存在,关注国际化与本土化的平衡。  相似文献

There are three models for community archives in China. The first one is where community archives are kept in government-funded/government-established museums or archives. The second is where community archives are kept by scholarly organizations such as universities. The third involves the community establishing its own archive. This last model is very unusual in China. The PiCun Culture and Art Museum of Migrant Labor (PCMML) provides an example of this model as it is the only independent community archives focusing on migrant workers in China. This paper explores the emergence and development of PCMML, its impact on community members and challenges faced including funding and staffing, but also those unique to China—PCMML is greatly influenced by a range of national and local government policies and regulations. Conclusions are that survival strategies for independent community archives in China are dependent on three dimensions: the community itself, society and the government. Cultural consciousness of the community is the premise for the establishment and sustainability of independent community archives, and independent community archives can be the public space to cultivate cultural consciousness of community members and thus activates community members’ agency to document, preserve and disseminate their own history. At the same time, independent community archives also need to engage with broader society to avoid involution and gain support and understanding. Independent community archives are constrained by government policies and regulations, so it is essential for them to develop strategic relationships with government.  相似文献

Textbook vetting and evaluation process intends to ensure that the materials provided are relevant, of the required quality, suitable ad would enhance learning efficiency and effectiveness. The paper investigates the role of publishers and Tanzania Institute of Education (TIE) in the textbooks vetting and evaluation process; examines factors used to vet, evaluate and approve primary and secondary school textbooks in Tanzania and proposes Strategies that would enhance the textbook vetting, evaluation and process. The study used a mixed method research design. Respondents were selected educational publishers; MoEVT, Baraza la Kiswahili Tanzania, TIE, and Publishers Association of Tanzania. Questionnaire and semi- structured interview were used to collect data which were analysed qualitatively and quantitatively. Major findings of the study were; textbooks vetting and evaluation process is not professionally conducted although standard criteria have been established; there is not well established roles among key players involved in the vetting and evaluation process leading to conflict of interest between TIE and the publishers. The study recommends establishing an independent professional evaluation board and a well-defined timetable and effective communication among various players; enacting a book policy and adopting a limited multiple-textbook publishing system.  相似文献

Our study compares the motivations of Australian and German book publishers. The results demonstrate remarkable similarities, but also a significant difference regarding the effects of the publishers’ self-concept. In the German case the publishers with a dominant economic orientation are more proactive than the publishers with a dominant cultural orientation. In the Australian case, this correlation does not exist. The same difference holds for the relationship between the economic orientation and extrinsic motivation. We discuss these results and examine empirical evidence and theoretical suggestions to explain the differing findings. The data stem from surveys conducted in the two countries with responses of 196 (Germany) and 54 publishers (Australia).  相似文献

Previous reports stressed on the importance of international collaboration and open access (OA) publishing, as they increase the quality of the research and increase its benefits. In this study, we will assess Jordanian international research collaboration and OA publishing in the past 10 years. We performed a Scopus search for Jordanian publications in the years 2008–2017, where we extracted and calculated the total number of publications, publications in OA journals, publications with international collaborations. Moreover, we assessed the disciplines Jordanians usually publish in. During the 10-year interval, we found a total of 20,359 Jordan-affiliated publications indexed in Scopus. We found a dramatic increase in number of publications with international collaboration from 38% in 2008 reaching 53.3% in 2017, and an increase in OA publications from 7.3% of the total publications in 2008, reaching 18.7% of the total publications in 2017. Total number of Scopus indexed publications from Jordan has increased by 57.9% over the past 10 years. Although international collaboration and OA publications have dramatically increased in recent years, Jordanian researchers should focus more on international collaboration with developed countries and on self-archiving their publications.  相似文献
