Chinese to Chinese Conversion

Chinese to Chinese Conversion

Over 700,000 items

Supports SC to TC conversions and vice versa

Supports orthographic and lexemic conversion


In 1996, CJKI launched a project whose goal was to develop a Chinese to Chinese conversion (C2C) system that supports Simplified to Traditional Chinese (SC>TC) and Traditional to Simplified Chinese (TC>SC) conversions that give near-perfect results. Orthographic conversion is mapping simplified forms to traditional forms on a character and word levels, such as SC 国家 to TC 國家 (‘country’) and vice versa, while lexemic conversion is mapping such as vocabulary items on a semantic level, such as SC 出租车 to TC 計程車 (‘taxi’) and vice versa.

C2C has been a major undertaking that required a considerable investment of funds and human resources. To this end, we have engaged in the following research and development activities:

In-depth investigation of technical and linguistic issues related to C2C

Research on Chinese word segmentation technology

Construction of comprehensive SC-TC mapping tables

To achieve a high level of conversion accuracy, our large-scale mapping tables include various other attributes, such as pinyin readings, grammatical information, part-of-speech codes, and semantic classification codes.


Each entry is accompanied by various attributes, such as:

Code level mappings

In the SC-to-TC and TC-to-SC directions

Semantic classification codes

Such as orthographic or lexemic codes

Lexemic mappings

In the SC-to-TC and TC-to-SC directions

Orthographic mappings

In the SC-to-TC and TC-to-SC directions

Phonological information

Such as pinyin and zhuyin

Grammatical information

Such as part-of-speech codes

Practical Applications

C2C is ideal for applications such as:

Machine translation into TC

Such as convert SC to TC instead of English to TC

SC-to-TC and TC-to-SC conversion

Machine translation into SC

Such as convert TC to SC instead of English to SC
