NSDL: Social Bookmarking for Digital Libraries: Improving Resource Sharing and Discoverability

该项目的目标是开发一个模型并实施一项服务，以使用社会书签功能扩展现有的NSDL基础设施，以促进对图书馆和相关开放教育资源(OER)库中资源的有效发现、搜索和探索。PI观察到，大多数数字图书馆并不以用户现在期望的方式维护和传播信息。因此，它们侧重于传统数字图书馆的三个基本问题：(A)用户期望与数字内容互动并使用社交模式访问它；(B)学习储存库未得到充分利用，需要以更具创新性的方式吸引用户；(C)需要更有效地检索与用户信息需求有关的图书馆内容。该项目使用大众分类法扩展了传统的基于Fedora的图书馆模型，并将其与新的查找相似方法相结合，以增强对图书馆和链接的OER存储库中资源的发现、搜索和探索。提出的寻找相似人的技术允许用户识别与他们有共同兴趣的其他个人，以及发现隐含的用户组。该项目预计将对数字图书馆和基于网络的教育系统产生影响。它的目标是通过利用社会元数据在储存库环境中扩展搜索工具的能力，这一目标可能在数字图书馆用户社区内产生广泛的影响。

The objective of this project is to develop a model and implement a service for extending the existing NSDL infrastructure with social bookmarking capabilities that promote efficient discovery, search, and exploration of the resources in the library and associated Open Educational Resources (OER) repositories.The PIs observe that most digital libraries do not maintain and disseminate information in the way users now expect it. Consequently, they focus on three fundamental problems in conventional digital libraries: (a) users expect to interact with the digital content and to use social paradigms in accessing it; (b) learning repositories are underutilized and there is need of attracting users in a more innovative way; (c) there is need for a more efficient retrieval of library content relevant to users information needs. The project extends a traditional, Fedora-based library model with folksonomy and combines it with a new find-similar method to enhance the discovery, search, and exploration of the resources in the library and the linked OER repositories. The proposed technique for finding similar persons allows users to identify other individuals with whom they share interests, as well as discovering implicit user groups. This project is expected to have impact on the digital libraries and web-based educational systems. Its goal of extending the capabilities of the search tools in repository context by leveraging social metadata may have a broad impact within the community of digital library users.
