Identification of works and expressions in line with FRBR and the development of retrieval systems to utilize identified works

为了按照书目记录功能要求（FRBR）概念模型转换现有的日本书目和权威记录，提出了识别资源中包含的作品和表达的方法，并验证了其有用性和可行性。对于日本古典作品和音乐作品等类别，建立了鉴定作品的判断标准，并使用这些标准手动鉴定作品。研究了自动识别作品的方法，并将结果与人工识别的作品集相结合。此外，一个FRBRized OPAC开发，有效地利用识别结果。相比之下，表达式识别由于其困难而被放弃。

To convert existing Japanese bibliographic and authority records in accordance with the Functional Requirements for Bibliographic Records (FRBR) conceptual model, methods of identifying works and expressions included in resources have been proposed and their usefulness and feasibility have been validated. Judgment criteria for identifying works were built for some categories such as Japanese classical works and musical works, and works were manually identified using those criteria. Methods of identifying works automatically were also investigated, and the results were combined with the manually identified work sets. Additionally, an FRBRized OPAC was developed to utilize effectively the identification results. In contrast, expression identification was abandoned because of its difficulties.
