Embodiment Construction

[0036] Embodiments of the present application are described below in conjunction with the accompanying drawings.

[0037] In related technologies, there is no good evaluation index for the labeling system of user portraits, which also leads to the established labeling system being either too coarse-grained and indistinguishable, resulting in inaccurate user portraits, or too fine-grained so that the labeling system is too complicated rather than universal.

[0038] In order to solve the above-mentioned technical problems, the embodiment of the present application provides a method for constructing an evaluation index of a tagging system. The method clusters semantically similar historical interaction samples into a tagged cluster according to the real situation, and the tagged The clustering results are used as the standard for evaluating the first labeling system. The clustering results of the first predicted cluster obtained by dividing multiple historical interaction sample...

Abstract

The invention discloses an evaluation index construction method of a label system and a related device. On one hand, label cluster clustering results of a plurality of historical interaction samples are obtained; and on the other hand, a first label of each historical interaction sample in the plurality of historical interaction samples is predicted according to a first label system of an object portrait, and the plurality of historical interaction samples are clustered according to the first label to obtain a first prediction cluster clustering result. According to the similarity between the labeling clustering result and the first prediction clustering result, an evaluation index of the first label system is constructed. The evaluation index can reflect the similarity between the first prediction clustering result and the labeled clustering result, the higher the similarity is, the more conformity between the first prediction clustering result and the real situation is, and the more reasonable the distinction degree of the first label system is. Therefore, the evaluation index of the first label system can accurately measure the advantages and disadvantages of the constructed label system, and then the label system with reasonable distinction degree can be more accurately constructed based on the evaluation index.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a method for constructing an evaluation index of a label system and a related device. Background technique [0002] User Profile (User Profile) is a tagged and virtual user model abstracted based on real information such as user basic attributes, social attributes, behavioral attributes, psychological attributes, etc., in order to understand user needs and preferences through user portraits, and then provide users to provide better services. As an effective tool to outline target users, connect user appeals and design directions, user portraits have been widely used in various fields such as dialogue products, personalized recommendations, and precision marketing. [0003] In order to create a user portrait, it is necessary to define the portrait features of each dimension and the value of the portrait label of each dimension, that is, to construct the label system of th...
