  1. An example of a synonymous word entry in SynonymDict (assuming the word length n = 4). WGPV is a synonymous word of proteins A, B and C, since it is extracted from the similar proteins of A, B and C. We record the structural information of protein sources to the corresponding synonymous words, and calculate the corresponding similarity levels and frequencies. For example, the similarity level of WGPV in terms of protein source A is 3 and the frequency is 7.
