Abstract: Semantic transparency refers to the degree to which the meaning of the whole word can be inferred from its constituents. For Chinese, semantic radicals generally carry information about the meanings of Chinese characters, and thus can be used to reflect semantic transparency of Chinese characters. For those Chinese characters having the same semantic radicals (i.e. neighbouring characters), their meanings are assumed to be semantically related to each other. However, to what extent those neighbouring characters are close in their meanings remains unclear. A conventional crowdsource approach could provide a coarse measure of semantic relationships between semantic neighbours. However, those approaches are generally limited to a small sample size of characters. Here, we proposed a corpus-based measure of semantic transparency, termed semantic radical consistency (SRC). Specifically, we utilised the Word2Vec models to construct a Chinese semantic space and quantified the SRC for 3,423 characters. To evaluate the SRC, we first conducted linear mixed-effect modelling (LMM) analyses to verify the explanatory power of SRC on a large-scale Chinese character naming RTs. Secondly, we investigated the SRC effect by conducting a word naming task based on traditional factorial designs. Both the LMM and factorial naming results demonstrated that SRC was a unique and reliable variable to account for the variance in traditional Chinese character naming RTs. The results indicated this innovative, corpus-derived SRC was able to effectively reflect the semantic transparency level by measuring semantic distances among characters in the same semantic radical category. Further investigations on the interaction between SRC and phonetic radical consistency demonstrated the cooperative nature between phonological and semantic reading pathways.
