In such work the basic background of big data or visualization technologies can’t be neglected and the thesaurus has been already used usually in medicine and chemistry fields. Some basic theory of semantic knowledge network and the birth of the foundation and construction methods of SSKN were also introduced. There is a strong contact between the birth and development of SSKN, and the collation of scientific knowledge network, the birth of big data technology and the mature of visualization methods. Finally, an empirical study and their evolution about semantic knowledge networks in the medical informatics was selected to make the SSKN clear for readers.
