In recent years,the development of technologies such as artificial intelligence and big data has brought opportunities for the development of Information Science.However,scholars in the Information Science community often confuse intelligence analysis with data analysis,and intelligence analysis research has the tendency of over big data or is weakened into data analysis research.In order to avoid such problems,this paper analyzes the relationship between intelligence analysis and data analysis.Through comparative analysis,it is found that data analysis is the basis of intelligence analysis,and big data analysis is an important component of the data analysis method system,but it cannot replace intelligence analysis.The differences between intelligence analysis and data analysis are obvious.From the dimension of data object,the data analysis method focuses on processing single-source data,and the intelligence analysis method mainly deals with the related full-source data.From the perspective of output results,data analysis yields new information and new knowledge,while intelligence analysis yields new intelligence.From the dimension of the starting point of analysis,data analysis is mainly driven by data,while intelligence analysis is mainly driven by goals.From the analysis method perspective,data analysis is mainly based on quantitative analysis,and supplemented by qualitative analysis,inductive reasoning,and deductive reasoning,and intelligence analysis mainly focuses on quantitative analysis at the stage of outputting new information and new knowledge,and inductive reasoning and deductive reasoning at the intelligence output stage.
