Evidence recording in bibliographic data and descriptive metadata : its efficient recording and effective utilization.

除了值本身之外，在书目记录和描述性元数据中记录数据元素值的证据可能有助于提高这些记录的表达性和可靠性，并最终提高它们的使用寿命和互操作性。记录的证据表明为什么以及如何记录元素的数据值。本项目研究了几种高效记录和有效利用此类证据的可能方法。支持编目员记录证据：设计了一个场景：(1)利用记录的证据，编目员参考这些证据，了解在给定元素中记录数据值所采用的方法；(2)编目员和系统在将这些证据记录到账簿记录中时相互作用。根据这一设想，已经确定了要记录的证据的适当内容，并开发了一个原型系统。实验验证了该系统的性能，结果表明了该系统的实用性。编目员利用记录证据：为编目员开发了一个系统，使其能够灵活地检索和显示记录证据和书目记录。利用记录证据自动识别重复记录：采用了使用记录证据进行重复记录识别的场景，在这种情况下，记录证据是待描述项目的信息来源的副本。开发了一个原型系统，通过书目记录之间的匹配以及源书目记录与目标书目记录的记录副本之间的匹配，来判断书目记录是否重复。

Recording evidence for data element values, in addition to the values themselves, in bibliographic records and descriptive metadata is likely to be useful for improving the expressivity and reliability-and finally longevity and interoperability-of such records. Recorded evidence indicates why and how data values are recorded for elements. This project has studied several possible ways of the efficient recording and effective utilization of such evidence.1. Supporting catalogers for recording evidence: A scenario has been designed (1) for utilizing recorded evidence to which a cataloger refers for information and understanding of the ways that had been adopted to record data value (s) in a given element and (2) in which a cataloger and a system interact with each other in recording such evidence in records for books. In line with such a scenario, the proper content of evidence to be recorded has been determined and a prototype system has been developed. The system's performance has been experimentally examined, the results of which show its usefulness.2. Utilizing recorded evidence for catalogers: A system has been developed for catalogers to retrieve and display recorded evidence together with bibliographic records in a flexible way.3. Utilizing recorded evidence for automatic duplicate records identification: A scenario for using recorded evidence for duplicate records identification has been adopted, while in this case the recorded evidence is the copy of the source of information of an item to be described. A prototype system has been developed to judge whether bibliographic records are duplicate with the results of the matching between bibliographic records and also between recorded copies of the sources and target bibliographic records.
