Abstract

The embodiments of the invention disclose a teaching video course credit evaluation method, which is designed to resolve the problem that the current teaching video course credit evaluation is too subjective and not accurate. The method comprises: obtaining the various teaching handout pictures and audio data in a targeted teaching video; performing text identification to the text contents in the various teaching handout pictures to obtain the keywords of the texts; performing speech recognition to the audio data to obtain the keywords of the speeches; matching the keywords of the texts and the keywords of the speeches with the keywords of the various knowledge points in a preset systematic knowledge base to obtain the successfully-matched keywords of the knowledge points wherein the systematic knowledge base records the keyword course credits corresponding to the keywords of the various knowledge points; and based on the keywords of the successfully matched knowledge keywords and the corresponding keyword course credits, calculating the course credit for the targeted teaching video. The embodiments of the invention further propose a teaching video course credit evaluation device.
