为了解我国煤炭科技期刊编辑部编辑出版专业研究水平与发展现状,采用文献计量学方法,以中国知网为检索平台,以作者单位(期刊编辑部)为检索词,依次对行业48种期刊编辑人员发表的编辑学论文数量、论文主题及期刊分布等情况进行统计分析.结果表明:近年来编辑人员发文量逐年增多,48种期刊编辑部共发表论文296篇,分布在75种期刊上;论文内容以编辑出版实践总结为主,编辑学研究水平偏低,对编辑出版前沿性问题,如文献计量学方法、数字出版、期刊产业化等热点内容研究较少.建议期刊主管(主办)单位、期刊编辑部及编辑自身3个主体通过完善政策、加强编辑业务培训、开展编辑出版研究项目等措施激励编辑人员撰写论文,以提高编辑业务水平和期刊质量. 相似文献

为了满足检索用户对推荐服务日益迫切的需求,结合检索词推荐需求研究推荐理论。基于三种典型推荐方法：基于内容的过滤、基于规则的过滤和基于协作的过滤,提出一种检索词的混合推荐方法,并基于检索日志构建一种“脱机预处理和挖掘、联机推荐”的检索词推荐模型。最后,在NSTL嵌入式系统上进行实证研究。基于检索日志数据,以简单检索方式下的检索词推荐为突破口,设计一套原型系统,验证检索词的推荐效果并在原型系统上检验一种改进的BWP方法的效果。 相似文献

单汉字标引技术的改进研究 总被引：10，自引：0，他引：10
王淼 《现代图书情报技术》1997,13(2):48-53
本文针对汉语构词的特殊性, 提出了一种单汉字标引的改进算法。该算法在标引上采用了对非检索词词首字的剔除标引, 在检索上, 采取检索词首字查找, 检索词直接匹配的算法。还提出了对检索结果的存储以及构筑后控词典, 以逐步完善单汉字检索系统。以上算法, 在SCIRS (Single Chinese Character Indexing and Retrieval System) 得到初步实现。 相似文献

在综合国内学术信息检索服务的现状和现有理论方法研究的基础上,以检索词推荐为研究对象,构建基于文献特征项共现网络的学术信息检索词推荐模型。模型包括基础文献存储模块、文献特征项抽取模块、文献特征项共现网络预处理模块、基于特征项的文献检索模块及检索词服务前端5个部分。利用实验验证基于特征项的共现网络用于检索词推荐的可行性,结果表明推荐模型结果与各检索项的检索词更具有相关性,推荐质量较好。 相似文献

[目的/意义] 旨在对国内图书馆面向突发公共事件应急服务与管理方面的文献进行梳理,分析该领域的研究与实践现状,为日后该领域的研究提供参考。[方法/过程] 以 CNKI 为数据来源,从数据库中选取相关文献,采用内容分析、理论与实践相结合的方法,对有关文献进行全面分析、梳理和归纳,重点分析图书馆面向汶川地震、防控非典、禽流感、甲型H1N1流感以及防控新冠肺炎疫情等突发公共事件的应急服务与管理方面的理论与具体实践。[结果/结论] 不同时期,应对不同类型突发公共事件,图书馆应急服务与管理的内容、方式方法有所不同。从早期意识到突发公共事件对图书馆的影响,到后来图书馆建立应急预案、采取应急措施、开展应急服务,图书馆界面向突发公共事件的服务与管理越来越重要、越来越规范,效果越来越明显。尽管如此,仍存在一些问题和不足,值得进一步研究和探索。 相似文献

This study applies the knowledge gap hypothesis to examine the direct and interactive influence of socioeconomic status, mass media, and interpersonal discussion on public knowledge of the H1N1 flu pandemic in Singapore. Using a nationally representative random digit-dialing telephone survey of 1,055 adult Singaporeans, results show that attention to newspapers was not associated with a widened knowledge gap about the H1N1 pandemic between the high and low socioeconomic status individuals. Conversely, attention to television news and interpersonal discussion were associated with a narrowed knowledge disparity between the high and low socioeconomic status individuals. Findings suggest that the knowledge gap hypothesis was not supported in this study. Instead, results suggest that attention to television news and interpersonal discussions were associated with a reduced knowledge gap. Household income and risk perceptions were also found to be positively associated with public knowledge about the H1N1 flu pandemic. Both theoretical and practical implications were discussed. 相似文献

To some the term avian flu or H5N1 has become synonymous with the pandemic flu of 1918. Like the former pandemic, this current threat has the potential to cause up to 7.4 million deaths worldwide. Yet as of mid-2006, the viability of this threat is still unclear. There is no doubt that birds, especially poultry, have been the primary target of this particular strain of influenza. Human illnesses and deaths have resulted from direct contact with birds; farmers and food handlers are most at risk. Fortunately there has not been a shift to human-to-human transmission. However, it is imperative for public heath officers, health professionals, and other appropriate officials to keep current on the progress of this virus within the bird population, and its spread around the world. Preventative measures including worst case scenarios have been widely discussed and even resulted in a made-for-TV movie. The need for up-to-date information is essential in order to track the extent of transmission, location of current outbreaks, and most importantly steps for preparedness that could be vital for prevention and containment. This article explores and identifies major Web sites along with basic Internet search techniques to find informative and credible Webbased resources. doi:10.1300/J115v26n01_06. 相似文献

The present study empirically operationalizes the health-related talk of married individuals (N?=?349) and reports on the factor structure of these health-related talk expectations and the reliability and convergent validity of the two-factor solution. Both factors were significantly correlated with participants’ self reports of marital satisfaction. Implications for the relationships between health-related talk and marriage are discussed. 相似文献

This article reports on a study that was designed to provide insight about the barriers that limit families with children with autism spectrum disorder (ASD) from visiting fine arts museums. Parents (N=54), and staff and volunteers (N=62) at the museum completed a questionnaire about their perceptions of the participation of children with ASD in museum activities. Some significant differences in responses were found between parents and museum staff and volunteers. Parents reported being thankful for the sense of community that Autism Awareness Family Celebrations provide, but were frustrated with reactions from others during typical museum experiences. Museum staff and volunteers expressed that museum participation was important, but responses were split between those who desired to learn more about ASD in order to create an optimal museum experience, and those who preferred not to take on this initiative. Studies such as this help museums become more inclusive. 相似文献

为评价H指数与影响因子、总被引频次的关系,以2009年《中国期刊引证报告》（扩刊版）中166种医学期刊的H指数、影响因子、总被引频次、引用刊数和来源文献量为源数据,采用SPSSl6．0软件作线性、对数、二次多项式、三次多项式回归拟合和Logistic回归。二维散点图和曲线回归拟合分析均发现,H指数与影响因子、总被引频次、引用刊数呈密切相关,但与来源文献量的相关性不强。因此,H指数、影响因子、总被引频次应相互补充,共同用于医学类期刊学术影响力的评价。 相似文献
