Comprehensive evaluation algorithm of English online teaching quality based on Artificial Intelligence

In view of the complex changing characteristics of English teaching quality, in order to obtain high-precision English teaching quality evaluation results, an English teaching quality evaluation algorithm based on principal component analysis and artificial intelligence is designed. This paper constructs the influence index of English teaching quality, optimizes and selects the evaluation index of English teaching quality by principal component analysis, and obtains the evaluation result of English teaching quality grade by artificial intelligence. The test results of specific application examples show that the proposed evaluation algorithm can accurately evaluate the English teaching quality level, and the evaluation results can provide valuable information for improving the quality of English teachig.
