A database for investigating the logographeme as a basic unit of writing Chinese.

Chinese script is non-alphabetic and a Chinese graph is basically syllabic which may consist of phonetic and semantic radicals with no representation of phonemes. The logographeme, a unit smaller than a radical, has been suggested to be the basic unit of Chinese writing based on data collected on people with aphasia. To better understand the role of logographemes in Chinese writing development, a data corpus of logographemes based on characters appearing in primary school textbooks is established.
