NSDL Service to Manage Distributed Collections

在对当前的馆藏做法进行研究之后，正在开发一套馆藏管理工具，使NSDL Path能够更轻松地管理资源。这项研究提供了对现有算法进行修改和整合以改进馆藏管理所需的背景。该项目的两个方面的目标是为那些消失的资源寻找类似的或替代的资源，以及使用语义分析来帮助确定资源是否随着时间的推移被重新调整用途或以其他方式改变。前者对收藏管理员很有用，使他们能够将新的和相关的物品带到他们的收藏中，而后者有助于保持收藏的有用性。预计这些工具将降低与资源保持链接的成本。

A set of collection curation tools that allow NSDL Pathways to more easily manage resources is being developed following a study of current curation practices. This study provides the background necessary to undertake the modification and integration of existing algorithms in order to improve collection management. Two facets of the project are the goal of finding similar or replacement resources for those that disappear, and the use of semantic analysis to help determine if a resource has been repurposed or otherwise changed over time. The former is useful to collection managers enabling them to bring new and relevant items into their collections, while the latter aids in maintaining the usefulness of the collection. The tools are expected to lower the costs of maintaining links to the resources.
