It is necessary to establish an improved online education evaluation index system based on big data technology.Then,according to the system characteristics,the subjective and objective evaluation data can be obtained,integrated and processed by different backstage from information systems of smart cam-pus.Next,based on the improved comprehensive-gradient algorithm,the optimal weights are computed and the scores are processed to get the composite scores that can reflect the actual teaching capability.Finally,the improved algorithm has been verified to confirm its effectiveness by trials.
