This paper presents a method for comparing the subject headings of Scopus and WoS classifiers that has been tested based on examples in the field of mathematical disciplines. Semantic relationships of subject headings are explored by using intelligent analysis of keyword and expression clustering. The results are presented in the form of a correspondence table for the subject headings of the classifiers.  相似文献

在国际著名的摘要和引文数据库Scopus中检索2015-2017年医学领域国际期刊的撤稿声明,收集并分析撤稿声明中的相关信息.检索后共获得1 015篇针对已发表正式论文的撤稿声明,声明数量逐年减少.发表撤稿声明较多的期刊,普遍质量不高,撤稿数量和期刊影响因子并没有明显的相关性.从Scopus上可以获得能提供有效撤稿相关信息的声明摘要共409篇,涉及文章419篇,学术不端是撤稿的主要原因,占所有撤稿原因的46.8%.撤稿文章来自38个国家,其中数量最多的为中国(97篇)、美国(95篇)、伊朗(53篇)、日本(28篇)、印度(22篇)、英国(14篇)、韩国(11篇).几乎所有国家的撤稿原因中都包括学术不端或重复发表.撤稿声明时滞为0~26年,中位数2年,平均值3.3年.学术不端的撤稿时滞中位数为3年,重复发表的撤稿时滞中位数为1年.  相似文献

This paper describes the topical-thematic structure of the “Political Science” Database created at the Institute for Scientific Information on Social Sciences (INION) of the RAS. The principles of conceptual processing of political science documents are considered. The properties are uncovered of how the complex of linguistic instruments (branch information-retrieval thesaurus, rubricator of political science, and subject headings) is developed and applied to indexing and classification of documents and queries.  相似文献

中国档案学研究内容广博,外国档案学研究内容精深;中国档案学研究主体以高校档案专业教师为主,外国档案学研究主体以档案实际工作者为主;中国档案学研究方法以定性描述为主,外国档案学研究方法以实证研究为主。中外档案学研究的明显差异性不是偶然出现的,它与中外档案事业管理体制、教育体系和各国研究历史传统、档案职业专业化水平等诸多因素都有关系,在本文中,作者对产生这三个方面差异的原因进行了分析。  相似文献

This is the third in a series of articles exploring international trends in health science librarianship in the first decade of the 21st century. The invited authors carried out a survey of librarians in Sweden, Denmark, Norway and Finland to identify common developments in their countries. A focus on pedagogy was seen as the most important trend. Future issues will track trends in Southern Europe and Latin America. JM.  相似文献

Background: Access to a comprehensive public health index or database has been identified as problematic for health professionals. Public health literature contains many varied sources including reports, journal articles, and grey literature. Traditional biomedical databases such as medline often do not meet the needs of public health workers and researchers. Aim/Methods: The aim of the study was to examine the unique content of the global health database, by comparing it to the medline database. Pre‐determined terms were used as baseline comparators where controlled vocabulary definitions in each database were sufficiently matched. Retrieved results were stored and compared using EndNote libraries. Results: Results obtained from the terms used in the comparison study protocol suggest that the global health database holds a high proportion of unique records in comparison to medline . The largest overlap of duplicates from the global health database perspective came from the coccidiomycosis results set which contained 70.5% of references retrieved from both databases. Analyzing the results from a medline perspective, the subject with the largest overlap was dengue, with a 43% overlap. Conclusion: The results of this study show that the global health database is complimentary to medline in the subject areas of public health and global health.  相似文献

An initial discussion of Scopus and its development was published in volume 49, number 3 of The Serials Librarian. This article updates readers on the continuing progress in its development, including the integration of research performance measurement tools, Web and patent references, and other additions that have been made from the fall of 2005 through September 2007. Additionally, this article details the strides made regarding content covered within Scopus, including the addition of seven million archive records in early 2007 and the agreement with ProQuest to link through to its arts and humanities selection through Scopus.  相似文献

中外期刊出版管理比较   总被引:2,自引:1,他引:2  
涂晓华 《编辑学报》2010,22(4):374-376
为提高中国期刊业的竞争力,从中外期刊业出版管理的角度,考察了中外期刊特别是科技期刊的办刊管理、出版立法、开放存取模式、经济调控机制、行业组织管理.认为我国对期刊业的管理方式应转向主要以经济、法律手段进行的间接管理,行业组织的行业管理职能应得到强化,同时期刊发展应顺应世界学术出版潮流,加强开放存取建设.  相似文献

以F1000数据库中生物信息学和免疫学近2 000篇文献为样本,多角度探讨WoS与Scopus数据库的优劣,其中包括两个数据库中被引频次的相关性、与F1000因子的相关性、主要评价指标数值及排序的相关性、历年被引累积量与被引总量相关性、多维空间感知图下的指标间相关性。结论指出:虽然各项指标源于WoS与Scopus不同的数据库,但是就被引频次及与F1000因子关系而言,两库具有较好的一致性;两库的主要评价指标,无论是数值抑或是排序,均体现出高度相关。上述结果可为科研评价中两个数据库的替代性和选择性提供借鉴,同时为定位在开源Scopus系统的利用提供有力依据。  相似文献

The connection between democracy and transparency would appear to be strong. Democratic countries have been among the earliest adopters of new legislation in transparency reforms such as access to information (ATI) laws. However, research has not yet tested the connection in the context of democratic reform where transitioning countries have the option to adopt ATI laws, and yet may, nevertheless, neglect or delay passage of such laws. To address this question, this paper uses Fuzzy Set Qualitative Comparative Analysis (fsQCA) with 23 countries that are in democratic transition in the fourth wave of democratic transition in the 21st century. The results show that low political competition in conjunction with strong civil society, regional pressure and recognition of international norms is favourable to ATI adoption. In contrast, the non-ATI adopters have encountered high political competition coupled with low regional pressure, weak international norms, and weak press freedoms.  相似文献
