Embodiment Construction
[0064] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0065] like figure 1 As shown in , an aspect-level sentiment analysis method based on BERT and the aspect feature localization model described in the embodiment of the present invention includes the following steps:
[0066] Step S1. Use the BERT model to obtain high-quality context information representation and aspect information representation to maintain the integrity of text information; specifically, use the pre-trained BERT model as a text vectorization mechanism to generate high-quality text feature vector representations , the BERT is a pre-trained language representation model, the text...
