Role of Data Mining in Big Data Finance

The proliferation of computer technology and personal computers, along with the development of storage media and electronic devices, has led to an explosive growth in the amount of information stored by human society. Almost all of this information is presented in the form of data. While the increase in information has brought many conveniences to human society, it has also introduced some problems. For example, some information is lengthy, trivial, or even incorrect, making information filtering and reliability a concern. As the volume of information increases, people need to spend more time and effort to sift out useful and reliable information. Information security is also a problem; as we increasingly rely on digital technology to store and share information, cybersecurity, and data privacy have become important issues. The phenomenon of “rich in data, poor in knowledge” is quite prominent.
