面向关联数据的实体链接发现方法研究

随着关联数据应用的不断深入,已有众多的数据集发布在网上,但目前已发布的关联数据集之间关联很少,为数据的共享使用带来不便。本研究提出一种基于统计学习方法进行关联数据集间实体识别及链接构建的方法。首先进行数据集间的实体匹配,采用基于K中心点聚类算法实现属性的聚合及关系发现,对具有高相关度的属性进行匹配关系描述,降低实体匹配时的属性匹配计算次数;其次对已匹配的属性进行实体属性值的相似度比较计算,实现实体间相似度的比较,在SILK框架下实现实体的链接构建工作,以达到实体链接发现的目的;最后通过实验验证,这一方法能降低数据集间实体匹配计算次数,提高实体链接的正确率,具有可行性及实用性。图12。表4。参考文献19。     

Designing User-Centered Discovery and Access Services for Enhanced Virtual User Experience

In 2010, the Technical Services Department at the University of Nevada, Reno Libraries established its top strategic direction to understand users’ workflows and strive to build seamless information access services around their workflows. To advance this strategic direction, an innovative reorganization was implemented within Technical Services by creating a new Knowledge Access and Discovery (KAD) Librarian position and forming a new Design and Discovery (DD) department from existing staff. In this session, the presenters discussed the shift to user-centered services, the roles of the KAD Librarian and the new DD department, their projects and initiatives, and how they work with the library-wide cross-departmental Virtual User Experience Committee to meet the Internet-fueled do-it-yourself (DIY) mindset of today’s library users.

Determining the Effectiveness of Digital Reference Services in Malaysian Academic Libraries

The aim of this study is to determine the effectiveness of digital reference services in academic libraries in Malaysia. It focuses on the awareness, usage, users' perception, library's performance, perceived needs, issues, and problems faced by students. The research methodology employed was a case study approach that combined three data collection methods: questionnaires, interviews, and content analysis.     

Improving Reference Services Through a Library Website: Strategies for Collaborative Change

SUMMARY

Websites are virtual front doors to the university library for many distance education students and for those simply choosing to access the numerous resources available to them through the library from off-campus. A driving force behind the redesign of the library website was to provide a user-friendly, content-rich website that offers assistance at the point of need, wherever the student is located. The University of Oklahoma Libraries' Web Committee's research and development focus combined with a collaborative environment provided a positive impetus for change to the library website and improved reference services to the University community.     

Improving Library Services for Distance Learners: A Literature Review

Academic libraries offer many services to distance learning students. The sources of literature reviewed here offer information that shows relevant similarities and differences between library services offered to traditional students and distance learning students. Likewise, the associated findings from the literature offer insight that is applicable for a project to modify and improve library services for distance learners in higher education.     

Beyond Circulation: The Evolution of Access Services and Its Relationship to Reference Librarianship

Academic libraries have undergone a variety of organizational changes in the last two decades. One area that has evolved out of these changes is access services. Relationships between circulation, interlibrary loan, and reference have been explored though informal and formal organizational structures. Because of these types of interactions it is feasible for reference librarians to consider positions in access services.     

Improving Research and Learning in Higher Education in Portugal: Digital Resources,E-Books,and a Discovery System as Enabling Factors for Students

ABSTRACT

This article describes a library's implementation of digital resources for research, teaching, and learning at a higher education institution in Portugal. A school specializing in education and teacher education established strategic performance areas related to digital resources for the fulfillment of its mission, which included some functions of the academic library. The library implemented a discovery system, and the school invested in a wider range of resources, including e-books, both acquired and institutionally published. The library's training programs were also revised to promote the new system and electronic resources. This case study describes how an academic library in Portugal responded to institutional needs, illustrating how libraries everywhere must connect to the larger vision and demonstrate value through technologies, integrating digital and print resources to provide access built around users' needs.     

Our Experience with Two Virtual Reference Services at IUPUI University Library

Summary

Indiana University Purdue University Indianapolis (IUPUI) University Library first introduced virtual reference in May 2001 after four months of preparation. In the summer of 2002, University Library decided to reconsider the virtual reference software and provider and implemented a new service during the fall 2002 semester. A Reference Team Working Group was formed to review replacement options for the virtual reference software the library had been using for about a year. The decision to find a new virtual reference service was prompted by the connectivity and electronic resource compatibility problems experienced with the first virtual reference software the library chose. This article compares and contrasts the two virtual reference services used at IUPUI University Library and describes the two virtual reference projects. Following the article is a checklist of “Seven Questions to Ask When Choosing a Virtual Reference Service.”     

“Packaged” Information: How are new Means of Delivering Information Affecting Students’ Information-Seeking Behavior?

This article explores two methods of “packaging” information for students: custom textbooks and web-based discovery services. It examines the implementation of each of these initiatives at the University of Reading, using the institution as a case study to explore the implications on students’ information-seeking behavior. This is combined with a review of the relevant literature surrounding each service. Custom textbooks were used by the University's History department to support one of its first-year undergraduate modules, with the aim of providing a source of essential reading. The University Library released its web-based discovery service to students in October 2011. Various effects on information-seeking behavior are observed, including the potential decline of critical thinking in order to evaluate sources and the danger of sidelining search skills in favor of easy information solutions. The article concludes that librarians have an important role to play in helping students to understand the complexity of information searching. Whilst custom textbooks and discovery services are in some ways beneficial to students, they still require guidance from expert library staff to help them navigate these resources as independent learners. Finally, topics for further research are presented.
