This paper interprets the connotation of Information Literacy as information literacy, and advocates that information literacy should be more prominent in terms of subjective quality and personality. For the first time, the concept of "information literacy chain" is put forward and its composition is expounded. Based on object, content, technology, information chain and extension dimension, a multi-dimensional relationship model of information quality chain is constructed. At the same time, information literacy can be evaluated scientifically by means of tools intervention, such as big data, artificial intelligence, cognitive computing, and emotional computing and so on.
