English MOOC Teaching Platform Design System Based on KMP Algorithm

English course is a language course which can be really improved only through a lot of interactive communication. The MOOC platform can help build a language environment where learners can train their spoken language and engage in conversational practice with teachers and other learners. Based on this, this paper designs and develops an English MOOC teaching platform that is easy to operate and has relatively complete functions, mainly in order to better facilitate English teaching for teachers, cultivate students’ interest in English, broaden their thinking, and improve learning enthusiasm. After testing the concurrent access performance of the teaching system(TS), it is found that the teaching platform can meet the needs of multiple users. In order to ensure the security of the teaching platform, this paper also introduces the KMP algorithm to prevent the system from being maliciously attacked. The KMP algorithm can be used to mine information that is unfavorable to the system, thereby ensuring the normal operation of the system server.
