项目摘要

The aim of this study was to investigate the usefulness and feasibility of creating bibliographic data and metadata principally based on text-level bibliographic entity in bibliographic database construction. In modeling the current practice, bibliographic data and metadata are created in principle based on manifestation-level entity which indicates the physical embodiment of a work―an intellectual or artistic content itself. In this study, instead of manifestation-level entity, text-level entity was adopted as a primary one ; text can be defined as the intellectual or artistic realization of a work in the form of alpha-numeric, musical, or choreographic notation, sound, image, object, movement, etc.1. Proposing a conceptual model giving primacy to text-level entity.A new model that gives primacy to text-level entity was proposed by using the E-R modeling language. The model consists of bibliographic and other entities including the text-level one, their attributes, and relationships between those entities. By applying the concept 'user tasks' to the new model, a scenario on how entities are used by users was outlined.2. Making bibliographic data in line with the proposed model.(1) Possible ways of creating bibliographic records in accordance with the model were categorized, and one was selected as the most appropriate.(2) Conversion was tried from existing bibliographic records created in the current practice to new ones structured under the way selected. Difficulties were also identified in the process of algorithmic conversion by computer program.(3) A prototype system was developed to make full use of the records converted from existing ones.

摘要本研究旨在探讨以文字级书目实体为基础建立书目数据与元数据在书目数据库建设中的实用性与可行性。在对当前实践进行建模时，书目数据和元数据原则上是基于表示作品的物理体现（知识或艺术内容本身）的表现级实体创建的。在这项研究中，而不是表现层面的实体，文本层面的实体被作为一个主要的;文本可以被定义为智力或艺术实现的一个工作的形式，字母数字，音乐，或舞蹈符号，声音，图像，对象，运动等。提出了一种赋予文本级实体优先权的概念模型，利用E-R建模语言提出了一种赋予文本级实体优先权的概念模型。该模型由书目和其他实体组成，包括文本级实体、它们的属性以及这些实体之间的关系。通过将“用户任务”的概念应用到新模型中，给出了用户如何使用实体的场景.使书目数据符合所提出的模型。(1)对按照该模式创建书目记录的可能方式进行了分类，并选出了最合适的方式。(2)尝试将现行做法中创建的现有书目记录转换为根据选定方式构建的新书目记录。在通过计算机程序进行算法转换的过程中也发现了困难。(3)开发了一个原型系统，以充分利用从现有记录转换的记录。
