and storytelling: paths and methods of archives research on the perspective of digital humanities

mainly WU Baokang’s digital photo archives. The text consists of 6 volumes, mainly based on
the WU Baokang Academic Chronicle edited by XU Yongjun. At the level of data content, the
images are mainly photos of WU Baokang at different times and places, while the text provides
a complete and comprehensive description and summary of WU Baokang’s growth, revolution
and academic experience from the perspective of narrative. At the level of data management, the
Nanxun District Archives and the old photo website of the Institute of Information Management
of the National People’s Congress have carefully and professionally preserved and sorted out WU
Baokang’s archival data by using the method of “time and event”, and staged and annotated WU
Baokang’s revolution and academic life, which laid a certain foundation for the data organization
and development research of this study.

4.2 Archival data processing and visualization

4.2.1 Hierarchical “discovering” of archival data
Guided by the “discovering” part of the methodological system, the processing process of WU
Baokang’s archival data is specifically divided into three levels: “metadata annotation”, “object
detection and extraction based on deep learning” and “context recognition”, and the content and
formal characteristics of archival data are correlatively anchored and mined from different angles.
First of all, at the level of metadata annotation, on the basis of referring to the Photo Electronic
Archive Metadata Scheme [37] (DA/T-54-2014) issued by the National Archives Administration, we
have designed a photo archive metadata annotation system including “physical layer”, “content
layer” and “element layer” based on the basic requirements and follow-up research needs of photo
archive metadata annotation, the main structure of which is shown in Table 2. After systematic
annotation and sorting of archival data, the corresponding display structure of WU Baokang’s
archival metadata and original archival materials was formed, and a coarse-grained association
between the metadata system and the archive item was established to meet the batch processing
needs of archival data thereafter.
