Visual information classification technique of Chinese tourism government portals

The development of new visualisation technology application tools and platforms is driven by the growth of visualisation technology application requirements and the continuous expansion of the Internet users. Based on the conception and development of the concept of data visualisation, the authors classify and compare the technical tools applied in several kinds of data visualisation technologies and distinguish the visual expressions into traditional visual expressions and new visual representations. Then, they perform the statistical analysis of the information types of the tourism government portals of Guangdong Province, Jiangsu Province, Zhejiang Province, Shandong Province, and Sichuan Province, which ranks on the top five of total tourism revenue in 2017. Furthermore, they analyse people's preferences for information types and provide suggestions based on people's preferences for information types and the types of information derived from travel administration websites.
