面向学术图书的Altmetrics指标分析     

韩雨彤  周雨涵  杨伟超  刘晓娟 《图书情报工作》2018,62(14):91-97

[目的/意义] 探讨Altmetrics指标对学术图书影响力进行评价的有效性,为学术图书评价工作提出合理建议。[方法/过程] 获取Twitter提及量、Mendeley阅读量、在线书评数量以及馆藏量指标数据,对数据集的覆盖率、分位数等统计量分析后,将被引频数与Altmetrics指标进行了指标间相关系数检验,再对高Altmetrics指标值的学术图书进行年份分布、学科差异及图书主题等实证分析,探究各指标在学术图书影响力评价中的应用。[结果/结论] 传统计量指标被引频数与Altmetrics指标之间的相关性较低,说明Altmetrics可以作为学术图书评价的一个新视角,不同Altmetrics指标反映了学术图书影响力的不同维度。未来的学术图书影响力评价建议结合学术图书的年份、学科等特征,将传统的引文与Altmetrics指标相结合,探索更全面有效的评价机制。  相似文献   

基于LDA主题模型的学术谱系内知识传承研究——以谈家桢为核心的遗传学学术谱系为例     

刘俊婉  杨波  王菲菲  徐硕 《图书情报工作》2018,62(10):76-84

[目的/意义]学术谱系以知识传承的方式助推科学发展。研究知识传承特征,探索学术谱系传承模式及其学术产出影响效能,为探索人才成长规律及人才政策制定提供参考。[方法/过程]基于LDA主题模型,以遗传学领域谈家桢为核心的学术谱系成员发表的期刊文献为研究对象,对该谱系成员的研究主题进行抽取,借鉴生物学"遗传"与"变异"的概念,根据主题相似度将谱系成员划分为"遗传学者"变异学者"和"非遗传非变异学者",并对三种学者的学术绩效进行分析。[结果/结论]分析结果表明,谈家桢学术谱系内"遗传学者"和"变异学者"的学术绩效相对较高;"非遗传非变异学者"的数量占比最多,但学术绩效相对较低;"遗传学者"与"变异学者"在不同主题下的分布具有明显差异。  相似文献   

基于词向量扩展的学术资源语义检索技术   总被引：1，自引：0，他引：1  

王仁武  陈川宝  孟现茹 《图书情报工作》2018,62(19):111-119

[目的/意义] 尝试以统计的方法为指导思想,探究基于词向量扩展的语义检索技术来提升学术资源的语义检索能力。[方法/过程] 利用自然语言处理、文本挖掘技术,对采集来的学术资源（主要是学术论文）元数据进行预处理,结合word2vec词向量生成工具和elasticsearch全文检索引擎搭建语义检索系统,对学术资源进行语义检索的探索研究。[结果/结论] 本文提出的方法能够有效提升学术信息的检索效果,一定程度上实现学术资源的语义检索,并为后续语义检索的进一步研究提供借鉴。  相似文献   

基于SKOS的学术期刊文本资源多粒度语义标注方法研究     

夏立新  郑路  张玉晨  翟姗姗  孙晶琼 《图书情报工作》2018,62(9):123-133

[目的/意义] 针对学术期刊文本资源语义标注仍存在的通用本体难以构建、标注粒度单一两大问题,提出基于SKOS的学术期刊多粒度语义标注方法,从而进一步推进语义标注的应用发展,更好满足用户的多粒度学术信息需求。[方法/过程] 在对《中国汉语主题词表》进行SKOS描述的基础上,以学术期刊文本资源为对象,实现其多粒度语义标注,并通过实证研究验证该方法的可行性。[结果/结论] 利用SKOS实现对学术期刊文本资源进行多粒度语义标注,较之当前学术检索系统中的标注结果,在"查全"查准"内部特征检索入口"检索结果反馈形式"4个方面具有一定优势。  相似文献   

Mandatory Student Fees and the Academic Library     

Jennifer L. Jones 《图书馆管理杂志》2018,58(1):54-64

As academic libraries' budgets remain flat while their expenditures rise, library leaders must seek out alternative sources of funding. One option is a mandatory student fee dedicated to the library. This article presents the results of a survey of 152 deans and directors of public R1 and R2 research universities that were asked whether their libraries benefit from mandatory student fees. While a library-specific fee is unusual, nearly half of responding libraries are eligible to receive some portion of another mandatory student fee. Study results can serve as evidence for libraries preparing to make a case for the significant, positive impact possible through even a modest library fee.  相似文献   

More Than Just a Student Voice: Facilitating Student Leadership Development Through the Library Student Liaison Program     

Suzanne Milton  Qing H. Meade 《图书馆管理杂志》2018,58(4):346-363

This article explores how the library-student liaison program at Eastern Washington University (EWU) Libraries has evolved into an opportunity for students to develop leadership skills. Originally designed to foster better communication between the EWU Libraries and students enrolled at the university, we recognized that the process of achieving established goals for the program provided a vehicle for students' leadership-skill development. To facilitate the leadership process, librarians employed the Social Change Model. Designed specifically for college students, this model engages the student to develop individual capacities to strengthen group activities that foster positive changes in the community and society.  相似文献

Clinical Medical Librarian Licensure: Pros versus Cons     

John Bramble  Shawn Steidinger  Claire Hamasu  Melissa Austin 《Medical reference services quarterly》2018,37(3):306-311

In hospitals and clinics, anyone who “touches” a patient has a license authorizing them to do so—from the phlebotomist to the cardiologist, from the genetic counselor to the social worker, and so on, except for the clinical medical librarian. This column discusses the intent versus the realities of occupational licensure for clinical medical librarians and provides recommendations for next steps.  相似文献   

Preparing for Practice: Strengthening Third-Year Medical Students’ Awareness of Point-of-Care Resources     

Tamara M. Nelson 《Medical reference services quarterly》2018,37(3):312-318

This column describes the development and implementation of a responsive library course designed to train third-year medical students as they begin their clerkships. The course design consisted of a brief face-to-face introduction during third-year orientation and an online course developed in Canvas, an online learning management system. The objective of the course was to not only introduce students to the resources but also to teach them how to effectively use those resources at the point-of-care. Students evaluated the course to assess the overall effectiveness of the instruction. Course development and content, feedback provided by students, as well as suggestions for improvement are discussed.  相似文献
