HKIUG TSVCC Table

Attempts to create TSVCC (Traditional, Simplified, Variant Chinese Characters) links for Chinese characters began in 2004. TSVCC linking allows retrieval systems to implement search logic so that searching one form of a character will also retrieve all the other forms. This linking information is particularly essential for native Unicode database system. Unlike EACC-based system that can make use of EACC's internal structure for linking, Unicode-based system has to rely on external resource in order to implement such linking logic. There are two versions of the HKIUG TSVCC Table, one for EACC-based systems (version 1.0.5, released on 14 November 2013) and the other for Unicode-based systems (version 1.0, released on 18 July 2006). Linking of TSVCC was developed by the HKIUG (Hong Kong Innovative Users Group) Unicode Task Force, chaired by Ki Tat Lam of Hong Kong University of Science and Technology Library. HKIUG and the Unicode Task Force were dissolved on 30 June 2017.

自2004年起，致力于构建传统、简体及变体汉字（TSVCC）之间的关联工作便已展开。TSVCC关联机制使得检索系统得以实现搜索逻辑，确保单一汉字形态的搜索能够同时检索出其所有变体形态。此类关联信息对于原生Unicode数据库系统尤为关键。与能够利用EACC（扩展ASCII编码）内部结构进行关联的EACC基础系统不同，基于Unicode的系统必须依赖于外部资源以实现此类关联逻辑。HKIUG TSVCC表格存在两个版本，一为EACC基础系统版本（1.0.5，发布于2013年11月14日），另一为Unicode基础系统版本（1.0，发布于2006年7月18日）。TSVCC的关联技术由香港创新用户组（HKIUG）的Unicode任务小组开发，该小组由香港科技大学图书馆的林啟達教授担任组长。HKIUG及其Unicode任务小组于2017年6月30日解散。
