This paper reports a rhetorical structure annotation project to a Chinese news commentary corpus Caijingpinglun(CJPL) for the purpose of natural language processing.The elementary discourse unit(EDU) in this project is defined as a string between two selected punctuation marks.And altogether 47 Chinese rhetorical relations are defined to mark the nuclarity according to the classic rhetorical structure theory(RST).A 60-page annotation manual with detailed rules of EDU segmentation,EDU combination,relation and scheme tagging protocols are composed.Analysis on the first manually annotated set of 97 texts shows that the RST has good cross-language transferability to Chinese,and the data obtained from this project may be further exploited in Chinese discourse processing.
