AbstractIn this second publication on the contextual SOMs of Chinese words, a new effect is reported. The SOM was trained by the complete MCRC corpus used in the previous publication. When its hit diagrams were formed using subsets of words of a certain word class with different word frequencies, the hit distribution was found to be a function of this frequency. An explanation of this effect might be that the usage of the words changes with time, and frequent use accelerates this transformation. Therefore, in planning new experiments on the contextually self-organizing word maps, one should be aware of this effect and take it into account in the selection of words to represent the word classes.
