The Thesaurus Linguae Sericae (TLS) is an Historical and Comparative Encyclopaedia of Chinese Conceptual Schemes and is designed as a collaborative forum for discussion on the close reading of Chinese texts for a cross-cultural study of conceptual history. It provides a corpus of classical Chinese texts wherever possible with interlinear translations. TLS links the texts incorporated with an analytic dictionary of the Chinese language.
The Thesaurus was founded by Christoph Harbsmeier (University of Oslo) and is developed by Center for Informatics in East-Asian Studies (Kyoto University). It is hosted by Princeton University, Department of East Asian Studies, in cooperation with Ruhr University Bochum, Forschungszentrum für traditionelle chinesische Kulturen.
