The invention discloses a text information processing device and method, computer equipment and a readable storage medium. According to one specific embodiment, the device comprises: an encoder based on a BERT model and used for extracting semantic feature vectors of a to-be-analyzed text; and an information processing module used for carrying out minimization solution on a target function comprising a first loss function and a second loss function according to the semantic feature vector of the to-be-analyzed text to obtain at least one aspect word contained in the to-be-analyzed text and the information polarity of the aspect word, wherein the target of the first loss function is to label the starting and ending positions of the aspect words in the text to be analyzed, and the target of the second loss function is to classify the information polarity of the aspect words. According to the embodiment, the end-to-end fine-grained information processing model capable of simultaneously realizing extraction of multi-aspect words and information polarity classification is constructed, and the accuracy rate and recall rate of fine-grained information processing can be improved.
