在构建多渠道元数据资源建设体系时,往往存在着大量的元数据冲突的问题,即对同一对象的属性存在多种描述,造成了元数据的组织与揭示的困难。本文处理的原则是遵从原文,优先选取原文的值作为唯一的真值,将数据冲突问题视为单真值冲突问题。考虑到数据提供商均需要加工数据,将数据源之间的关系视为相互独立。根据以上,本文提出了一种面向学术资源集成的真值发现算法。该算法基于贝叶斯算法,考虑了有关联关系的属性。实验证明本文方法所构造的真值发现算法在保证准确率的同时,大大节省了人力的工作时间。  相似文献

ABSTRACT

A study of job advertisements for technical services librarian positions provided insight into critical aspects of the library profession, issues that affect the work life of academic librarians. A review of several hundred job ads with a focus on job titles revealed problems with the use of terminology and the actual conceptualization of positions. Based on the ads reviewed, libraries also appear to be raising their expectations for types of knowledge and skills required and personal qualities desired.  相似文献

Universities need to maintain data about various resources. They include intellectual creations that are the focus of (Digital) Libraries, but also courses, research projects, and people. Data about intellectual creations are maintained in institutional repositories, while data about courses, research projects, and people reside in various databases designed to support specific vertical applications. We propose a uniform treatment of such resources leading to Digital Universities, i.e., a set of key resources, methodologies, and tools appropriately organized to effectively support universities' users. This requires new methodologies, data models, authority control mechanisms, and system infrastructures that are able to support a broader range of services.  相似文献

This article describes the Digital Library North (DLN) project, a collaboration among researchers at the University of Alberta, staff at the Inuvialuit Cultural Resource Centre, and communities within the Inuvialuit Settlement Region (ISR) to develop a culturally appropriate metadata framework for a digital library of cultural resources. It will discuss gathering of data to inform the first iteration of the metadata framework and digital library prototype, as well as revisions made to both the framework and the digital library based on feedback obtained through community interaction with the prototype.  相似文献

The authors review how access to historical aerial photograph collections has evolved in response to technological developments and addresses areas for further advancement, with a particular emphasis on developing, preserving, and sustaining online collections. The authors focus specifically on the areas of metadata, the Semantic Web and linked data, and sustainability through collaboration. The article includes brief case studies, highlighting various projects involving the aerial photography collections at the University of Minnesota. The conclusion asserts the critical role played by geographic information librarians in effectively carrying out the strategies described in the article as they relate to the long-term sustainability of digital geospatial collections.  相似文献

How we imagine records affects what we acquire and how we manage it. I take up the call from Arjun Appadurai to view archives as deliberate creations, and from Hugh Taylor to use imagination as a means of creative engagement with archival theory. I explore how we can reimagine archival work, mandates, and records by eschewing divisions of content and metadata, acknowledging items and aggregations to be interchangeable concepts, and integrating data about use into archival data management.  相似文献

This article presents a case study of quality management for print and electronic resource metadata, summarizing problems and solutions encountered by the Cataloging and Discovery Services Department in the George A. Smathers Libraries at the University of Florida. The authors discuss national, state, and local standards for cataloging, automated and manual record enhancements for data, user feedback, and statewide consortial factors. Findings show that adherence to standards, proactive cleanup of data via manual processes and automated tools, collaboration with vendors and stakeholders, and continual assessment of workflows are key to the management of biblio-graphic data quality in consortial academic libraries.  相似文献

This article describes a conceptual analysis of user-generated tags applied to video games in the Steam video game distribution system. The research team scraped all user-generated tags available on Steam and then conducted a conceptual analysis of the tags, sorting them into categories and comparing them to the current version of the Video Game Metadata Schema. This analysis allowed the team to identify new metadata elements and terms useful to game players. We present a discussion covering the major issues in organizing the terms, as well as the implications for the future work in the area of video game metadata.  相似文献
