In the smart classroom environment,due to the complexity of interactive behavior data,the accuracy of search results is difficult to guarantee.Therefore,the research on the method of precise search for interactive behavior data of smart classroom in the context of the"Internet+"era is proposed.A smart classroom interaction behavior data classification model has been constructed,which deeply analyzes the composition of smart classroom interaction behavior data from two dimensions:"human human interaction"and"human content interaction".In order to achieve precise search,a smart classroom interaction behavior data chromosome with a unique label was set up,which can accurately determine the search results based on the unique label of the target object.The test results show that after adopting the design method,the search accuracy of interactive behavior data is significantly improved,with a significant advantage compared to the control group.The recall deviation is basically stable within 5.0%,the maximum deviation is only 6.0%,and the minimum deviation reaches 0.
