Topic Analysis of Digital Preservation Based on BERTopic
Naishuai Zhang Jimin Wang
Digital Preservation refers to the series of managed activities necessary to ensure continued access to digital materials for as long as necessary, which has garnered widespread attention from institutions and individuals and has undergone extensive research. This study constructs a literature dataset based on Web of Science and Scopus, and applies the BERTopic model to identify themes and analyze development trends in the literature. The results show that research themes in digital preservation mainly include cultural heritage preservation and related technologies, data preservation, metadata and models, risk assessment and management, personal information, and website preservation, with libraries remaining key participants in digital preservation. The overall popularity of various research topics exhibits a fluctuating yet stable state, with research on cultural heritage preservation technologies such as 3D and laser showing an initial peak followed by a decline, while research on data preservation has been a consistent hotspot since 2009, albeit showing a downward trend in recent years. With the development of large language models, the importance of data has been elevated to unprecedented levels, and data preservation is poised to enter a new peak of research.
