Structure-Based Web Access Method for Ancient Chinese Characters

This paper presents a novel structure-based method for accessing Ancient Chinese Characters (ACCs). By formalizing the relationships between ACCs and modern characters, we establish a super-large font and an extensive database to facilitate the retrieval and management of ACCs online. The study addresses challenges related to existing input methods and software limitations in processing ancient characters, offering solutions for character generation, classification, and database schema. This research is crucial for preserving and accessing China’s rich historical heritage.

  2. Outline • Background • Formalization of relationships between ACCs and modern characters • Establishment of Super Large Font • ACC Database • Implementation and results

  3. Background (1/3) • Ancient Chinese Characters (ACCs) • Important heritage of Chinese history • Date back to at least 3300 year-old • Development is not one-dimensional • Collection, management, and access on the Internet

  4. Background (2/3) • Problems 1 • Involves very large quantities of modern characters

  5. Background (3/3) • Problems 2 & 3 • Lack of software code • Traditional IMEs are not suitable for ACCs

  6. Related work • 1993, Xusheng Ji • 1994, Ning Li • 1996, Fangzheng Chen • 2003, Zaixing Zhang • 2004, Zhiji Liu • 2005, Derming Juang • 2007, Yi Zhuang • 2008, James S. Kirk • 2008, Dan Chen • ... ...

  7. Outline • Background • Formalization of relationships between ACCs and modern characters • Establishment of Super Large Font • ACC Database • Implementation and results

  8. 2Formalization of relationships between ACCs and modern characters • Contemporary encoded characters • Existing encoded Chinese characters • Marks for uncoded Chinese characters • ACCs • Corresponding relationships with contemporary encoded characters • No corresponding relationships with the contemporary encoded characters

  9. 2Formalization of relationships between ACCs and modern characters • Two relations • Three Types of ACCs • Recognized characters • Ambiguous characters • Unrecognized characters

  10. Outline • Background • Formalization of relationships between ACCs and modern characters • Establishment of Super Large Font • ACC Database • Implementation and results

  11. 3Establishment of Super Large Font • Automatic generation of Chinese characters [27-30] • rules regarding glyph structure decomposition • redundant expressions of glyph structures are permitted • multi-level radicals

  12. Outline • Background • Formalization of relationships between ACCs and modern characters • Establishment of Super Large Font • ACC Database • Implementation and results

  13. ACC Database (1/3) • Relation Schema

  14. ACC Database (2/3) • Other relation schemas • Dynasty and Country (DC_RS), • Ancient C_Character Classification (ACCC_RS) • ACC Type (ACCT_RS) • Unicode and Glyph (UG_RS) • Radical and Component (RC_RS) • Ancient Image (AI_RS) • Contemporary Image (CI_RS)

  15. ACC Database (3/3) • Relationships of the data tables

  16. Outline • Background • Formalization of relationships between ACCs and modern characters • Establishment of Super Large Font • ACC Database • Implementation and results
