The digitization of ancient characters allows ancient writing materials to break the limitations of time and space. The application of digital technology can also help the interpretation of ancient writings and contribute to the protection of original materials. After more than 20 years of efforts, the research on digital processing of Chinese ancient characters has made a series of attempts in ancient character database and query system, big data platform, ancient character input software and recognition software, and achieved a series of achievements. In the future, we need to make continuous efforts in the interdisciplinary talent training of Chinese Palaeography and computer science, the cooperation between different research institutions, and the openness of digital achievements.

There are a lot of problems in the existing databases of ancient characters, such as the digital processing obstacles of Gaiji (characters excluded in character sets), the defects of information technology, and a lack of completeness. The newly released “digital resource library for intelligent Internet search of ancient characters” makes the following breakthrough: it achieves full coverage of all types of ancient characters in all dynasties, and realizes the carrier conversion of character data with strict digital standards, allows the the further processing of materials and the intelligent recognition search technology, and forms the series of thematic databases. There are two major tasks for the future development of the digital resource library of Chinese characters: the development of international standards for ancient character sets, and the further processing and sorting of ancient character materials for the intelligent research of ancient characters.
