Research on reliability test of hybrid information intelligent retrieval in Mobile English Teaching

In the new digital environment, digital literacy has gradually become the core skills of human survival. Since English teaching includes many modules, mobile English teaching platform is required to have the ability to deal with mixed information. At present, the existing mobile English teaching platform cannot deal with the mixed information of multiple modules, which leads to the problems of low precision and long time consuming. Based on the analysis of the problems existing in the construction of mobile English teaching information retrieval course and the requirements of the concept and ability of digital literacy, this paper constructs a multi-dimensional information retrieval teaching system from the perspective of digital literacy training from four aspects of teaching environment, teaching object, course content and teaching information. Experimental results show that the proposed system has ideal accuracy and running time.
