Chinese idiom knowledge base for Chinese information processing

In the vocabulary of Chinese language, idioms are a distinctive part for its fixed constitution grammatically and metaphorical meaning semantically. This paper introduces the entries and fields selected for the Chinese Idiom Knowledge Base (CIKB) built by the Institute of Computational Linguistics at Peking University (ICL/PKU) as well as its construction methods, research and applications so far. As a new member of the Comprehensive Language Knowledge Base (CLKB) constructed by ICL, our idiom knowledge base represents the new development of CLKB and will play a major role in NLP tasks such as machine translation, computer-aided translation, cross-language search, linguistic research, teaching Chinese as a foreign language and even as an electronic tool for preserving this non-material Chinese cultural and historical heritage. ? 2013 Springer-Verlag.EI
