GB/T 38548.1-2020 in English

Standard Background and Positioning

GB/T38548.1-2020, as the terminology basis of the content resource digital processing series standards, was proposed by the State Press and Publication Administration and managed by the National Press and Publication Information Standardization Technical Committee. The standard was issued in March 2020 and implemented in October of the same year, marking a new stage of standardization in the digital construction of content resources in my country.

Terminology Architecture

Analysis of key technical terms

4.8 Optical Character Recognition (OCR)

The standard clearly defines it as a technology that automatically recognizes characters in images obtained by scanners, digital cameras and other devices, and facilitates storage, editing and retrieval. In practical applications, it should be noted that:

• The recognition accuracy is directly affected by the image resolution (2.3)
• The processing of out-of-system characters (2.6) is a common difficulty
• It needs to be used in conjunction with layout analysis (4.9) technology

5.1 Metadata

The definition of GB/T5271.17 is quoted, emphasizing its core feature as "data about data elements". As a typical application, Dublin Core metadata (5.3) plays a key role in the construction of digital libraries.

Implementation Suggestions

1. Term Mapping: Establish a comparison table between the enterprise terminology library and standard terminology
2. Process Optimization: Refer to the standard operating instructions (4.4) to improve the processing flow
3. Quality Control: Use data quality (5.16) indicators to establish an evaluation system
