Information research is a method of using modern information technology and soft science research methods to form valuable information products by collecting, selecting, evaluating and synthesizing information resources. With the advent of the era of big data, the core work of information analysis with data is facing enormous opportunities and challenges. How to make good use of big data in an effort to solve the problem of big data, optimize and improve the traditional information research methods and tools, innovation and research based on big data are the key issues that need to be studied and solved in current information research work. Through the analysis of information research methods and common tools under the background of big data, we sort out the processes and requirements of the information research work under big data environment, design and implement a universal knowledge computing platform for information research, which enables intelligence analysts to easily use all kinds of big data analysis algorithms without writing programs.
