In order to achieve high-precision and high-efficiency visual retrieval of intelligent teaching resource data, this paper proposes a visual retrieval method of intelligent teaching resource data based on feature index. Firstly, a data mining model of intelligent teaching resources is constructed according to the similarity and feature extraction results of intelligent teaching resources, and then the data mining results are merged and classified. Finally, the feature index is constructed, and the data visual retrieval is realized by combining the similarity calculation results of the initial v...
