For example, Zhou and Xue (2012) use the PDTB annotation guidelines to annotate Chinese discourse with 98 files from Chinese Treebank (Xue et al., 2005b) of Xinhua newswire.
they adopt a lexically grounded approach and make some adaptation based on the linguistic and statistical characteristics of Chinese text, with Arg1 and Arg2 defined semantically and the senses of discourse relations annotated besides connectives and their lexical alternatives.
