SemTransCNC 1.0 is a semantic transparency dataset of Chinese nominal compound which was built using a series of Mechanical Turk-based experiments. It consists of the overall and the constituent semantic transparency (OST, CST respectively) data of 1,176 dimorphemic Chinese nominal compounds which consist of free morphemes and which have mid-range frequencies. The dataset is in CSV format which has 11 columns. The columns WORD and WORDT list Chinese nominal compounds in simplified and traditional Chinese characters respectively. The column STRUCT stores the morphological structure of the compounds. The columns FREQ and RFREQ show the absolute and relative frequencies respectively of the compounds according to the Sinica Corpus V4.0. The columns NOST, NC1CST, and NC2CST respectively store the overall semantic transparency value of each compound and the constituent semantic transparency values of both constituents of each compound; in these columns, 1 means completely transparent and 0 means completely opaque. The columns OSD, C1SD, and C2SD are the standard deviations of the overall and constituent semantic transparency rating data of each compound. Wang et. al. (2014, 2015, 2019) describes the details of the construction of the dataset. References: [1] Wang, S.; Huang, C.-R.; Yao, Y. & Chan, A.
