Data mining is the foundation, machine learning is the process, and natural language processing is the means of realization.

Both belong to the subdivision technology of cognitive intelligence, and there is an intersection between them.

We can understand the relationship between the three through the product logic of the small I robot of cognitive intelligence company. Data is raw material, and machine learning is the process of training robots, that is, through data mining, data is structured and arranged to form a knowledge map, which becomes the source of natural language processing and understanding by machines.
