Embodiment Construction
[0052] refer to figure 1 , the present invention provides a kind of Internet big data analysis extraction method, comprises the following steps:
[0053] S1. According to the characteristics of the data, the data objects are divided into different parts and types, and then further analyzed to obtain the range of data to be extracted;
[0054] S2. Determine the causal relationship between the variables by specifying the dependent variable and the independent variable, establish a regression model, and solve the parameters of the model according to the measured data, and then evaluate whether the regression model can fit the measured data well, if it can be very good If the fit is good, the range of data to be extracted can be further narrowed according to the independent variable. The similar matching algorithm can be applied to such as data cleaning, user input error correction, recommendation statistics, plagiarism detection system, automatic scoring system, web search and DN...
