Big data analysis method and artificial intelligence system applied to cloud online service

According to the big data analysis method applied to the cloud online service and the artificial intelligence system provided by the embodiment of the invention, the session emotion text and the session intention text in the online session behavior data are mined, so that compared with online session behavior characteristics of overall coarseness adopted in the prior art, the session emotion text and the session intention text in the online session behavior data are mined; the session emotion knowledge vector and the session intention knowledge vector can more accurately evaluate the feature difference between texts, so that the reliability of online session behavior data search is improved, and compared with an existing scheme in which one feature vector is independently extracted for each template behavior, the efficiency of online session behavior data search is improved. By obtaining the template session mining features including the session intention knowledge vector and the session emotion knowledge vec
