With the rapid development of the Internet, computers, and smart devices, the recorded data generated by human activities has exploded, and data has become an important resource. Since researchers proposed the concept of big data from storage and computing, respectively, with the deepening of understanding, people's understanding of big data has been developing, but others proposed “3V” (Volume, Velocity, Variety) and later expanding to “4V” (increasing the Value). However, Andersen (2014); Burnes (2014); Arumugam (2016); Zhan et al. (2018) proposed “5V” by adding the Veracity.
