Abstract : Based on the oracle bone glyph data in the “ZhongHuaZiKu”database, this paper designs a new input method coding scheme which is easy to search in the database, and provides a feasible scheme for the design of oracle bone glyph input method software in the future. The coding scheme in this paper is based on the experience of the past oracle bone inscriptions input method design. In view of the particularity of oracle bone inscriptions, the difference factors such as component combination, sound code and shape code ( letter ) are added, and the coding format is designed as follows : The single component characters in the identified characters are arranged according to the format of " structural code + pronunciation full spelling code + tone code " ; the multi-component characters in the identified characters are arranged according to the format of " structure code + split component pronunciation full spelling code + overall glyph pronunciation full spelling code”; unidentified characters are arranged according to the format of " y + identified component pronunciation full spelling + unidentified component shape code ( letter ) ".Among them, the identified component code and the unidentified component shape code are input in turn according to the specific glyph from left to right, from top to bottom, and from outside to inside. Encoding through these coding formats, the heavy code rate is low, and the input habits of most people are also taken into account. Keywords : oracle bone inscriptions ; input method ; coding
