[0032] Product Features: Weight

[0033] Emotional description themes: Machine is very light; easy to carry; smaller model for women; thin profile.

example 2

[0035] Product Features: Screen

[0036] Emotional description theme: clear colors; large size; high pixel.

[0037]Among them, a variety of learning models can be used to analyze and extract and identify the emotional description topics in user reviews associated with the characteristics of products or services, such as K-means clustering model, Bayesian classification model, etc. Preferably, topic models (Topic models) can be used to analyze the user comments associated with the features of the product or service to identify emotional description topics for the product or service. Figure 7 It shows in detail how to use the topic model algorithm to identify the topic of emotional description. In step 505, after identifying the emotional description topic, you can choose to generate a binary group such as , such as , , ,  …. Of course, any other suitable data structure may be used to describe product features and corresponding emotion description topics. In addition, it s...

Abstract

The invention provides a user comment processing method and a system thereof, as well as an information retrieval method and the system thereof, wherein the user comment processing method comprises the following steps: receiving objective data of characteristics of a product or a service and user comments about the product or the service; identifying the user comments which are associated with the characteristics of the product or the service from the user comments about the product or the service; identifying emotional description themes from the user comments which are associated with the characteristics of the product or the service; establishing the association relationship between the emotional description themes and the corresponding objective data of the characteristics of the product or the service, and further calculating the emergence frequency of the emotional description themes which are associated with the objective data; and forming the association rules between the emotional description themes and the objective data according to the association relationship and the emergence frequency of the emotional description themes which are associated with the objective data. The invention can accurately and deeply reflect the association relationship and the association rules between user emotion and the objective data of the product or the service.

Description

technical field [0001] The present invention generally relates to a retrieval method and a user review processing method and system thereof, in particular, to a method and system for processing user reviews of related products or services, and a system based on user reviews of related products or services A search method for products or services based on the knowledge gained through processing. Background technique [0002] At present, a large number of users hope to learn about the products or services to be purchased through the Internet. A more typical way is that relevant manufacturers or network service providers (such as digital product websites, hotel reservation websites, consulting service websites, etc.) provide users with information such as figure 1 In the search method shown, the relevant manufacturers or network service providers list the features of products or services that users may care about and their corresponding related data, and the buyers set relevan...
