Firstly, starting from the connotation of cultural gene and using culturomics as the theory, it summarizes the development history and the evolution, introduces some articles that use similar ideas to expand the theory of Cultural Computing, and simply compares some different methods of Cultural Computing. Then, presents the main research contents, including cultural gene which plays as essential information mode, cultural quantification and visualization analysi of big data application methods, which tells how they can get a quantified and scientific research on culture. Finally, the paper uses examples to introduce Cultural Computing more clearly, and has a outlook on it.
