Embodiment 1

[0023] A joint identification method of comment area and emotional polarity disclosed in the embodiment of this application, such as figure 1 As shown, the method includes: Step 110 to Step 130.

[0024] Step 110, determine the name of the comment object targeted by the target text and the comment dimension information matching the target text.

[0025] The comment dimension information includes: the name of the comment dimension and keywords associated with the comment dimension, the name of the comment dimension and the keywords associated with the comment dimension are determined according to the words with descriptive functions in the target text .

[0026] During the specific implementation of this application, the comment area in the target text and the emotional polarity of the target text are predicted through the pre-trained joint recognition model of comment area and emotional polarity. The input of the joint recognition model of the comment area and emotional pola...

Abstract

The embodiment of the invention discloses a comment area and sentiment polarity joint recognition method and device and electronic equipment. The method comprises the steps: determining a name of a comment object for a target text and comment dimension information matched with the target text, wherein the comment dimension information comprises the name of a comment dimension and a keyword associated with the comment dimension; constructing input data according to the target text, the name of the comment object, the name of the comment dimension and the keyword, and inputting the input data into a comment area and sentiment polarity joint recognition model; and estimating a comment area and sentiment polarity in the target text according to the context information between the characters carried by the target text, the name of the comment object, the name of the comment dimension and the area information carried by the keyword through the joint recognition model. By means of the joint recognition method for the comment area and the sentiment polarity, the comment area in the target text and the sentiment polarity of the target text can be recognized at the same time.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to a joint identification method, device, electronic equipment, and computer-readable storage medium for comment areas and emotional polarity. Background technique [0002] User-generated data (such as user reviews) usually includes different views of users on merchants or products. For example, in an Internet shopping application scenario, users' comments on online orders usually include different views of users on purchased merchants or commodities. Making full use of user-generated data and mining entity and opinion information in user-generated data is of great significance for merchants to improve product quality, improve service quality, and recommend merchants and products. In the prior art, the method of entity and opinion mining is usually to identify the entire comment data, identify the entities and / or opinions in it, and pre-identify th...
