The so-called intelligence analysis, also known as intelligence analysis, intelligence research or intelligence investigation, is an information labor process that deeply processes and analyzes a large amount of relevant information according to the needs of a specific problem and forms new information that is helpful to solve the problem.
With the rapid development of modern information analysis and consulting activities, information analysis is a new discipline derived from information science in the 1950s. In the past two or three decades, information analysis has developed rapidly in the process of information dissemination.
Understanding of information analysis
The understanding of this concept can be carried out from several elements that constitute this definition:
① From the cause of formation, the emergence of information analysis is due to the existence of social needs.
② In terms of methods, information science and soft science are widely used in information analysis.
③ From the flow point of view, information analysis needs to go through a series of relatively procedural links.
④ From the results, information analysis is a new value-added information product.
⑤ From the purpose, information analysis serves different levels of scientific decision-making.
The types of information analysis can also be divided according to the methods adopted. Generally, it can be divided into qualitative analysis and quantitative analysis. Qualitative analysis methods generally do not involve the relationship between variables, and mainly rely on people's logical thinking function to analyze problems; Quantitative analysis method must involve the relationship between variables, mainly based on the form of mathematical function to calculate and solve. Qualitative analysis methods such as comparison, reasoning, analysis and synthesis; Quantitative analysis methods, such as regression analysis and time series method. It is worth pointing out that due to the complexity of information analysis problems, the solution of many problems involves both qualitative analysis and quantitative analysis, so the combination of qualitative analysis and quantitative analysis methods is becoming more and more common.
