Example Embodiment

[0144] Example 1

[0145] As shown in the figure, the method for evaluating the quality of text comments in e-commerce provided by this embodiment includes the following steps:

[0146] Crawl review data, and at the same time classify review data by product category to build product review documents;

[0147] Use the topic analysis model to establish the association relationship between the product category, the topic and the feature words contained in the topic;

[0148] Use the formal concept analysis model to construct a virtual concept lattice with commodity categories as objects and topics as attributes;

[0149] Build a review quality evaluation model;

[0150] Obtain comment data and perform word segmentation operations on the comment data;

[0151] Input the word segmentation into the review quality evaluation model to evaluate the quality of the review data;

[0152] Output quality evaluation results.

[0153] The product review document is constructed through the following steps: ...

[0270] Example 2

[0271] The evaluation system of the transaction review quality provided in this embodiment can realize the objective evaluation of the transaction review quality. And can recommend the comments with higher evaluation quality to the transaction users, so that the users can refer to them in the transaction.

[0272] The system includes a product review document building module, through which the preprocessing of the review data fetched from the network is completed, that is, the review data can be classified by product category.

[0273] The system contains a topic analysis module based on review documents. The module uses the topic analysis model to extract product review topics, and uses these topics to establish associations between product categories, topics, and topics that contain words.

[0274] The system contains a virtual concept lattice construction module based on commodity categories and topics, which is used to construct a virtual concept lattice with co...

[0276] Example 3

[0277] The method for evaluating the quality of text reviews in e-commerce provided in this embodiment is a method for evaluating the quality of the reviews themselves. This method will evaluate the quality of reviews in terms of the relevance of reviews and products, the comprehensiveness of the reviews themselves, and the professionalism of the reviewers in the fields involved in the products. Finally, the larger the value of the review quality evaluation, the higher the review quality and the more reference to users.

[0278] The review quality evaluation system provided in this embodiment has a processing flow such as figure 1 As shown, it mainly contains four modules: a product review document building module; a topic analysis module based on a review document; a virtual concept lattice construction module based on commodity categories and topics; and a review quality evaluation module based on the virtual concept lattice.

Abstract

The invention discloses an evaluating method for the product comment quality in electronic commerce. The evaluating method includes the steps that comment data is grabbed to construct a product comment document; the incidence relationship among product categories, themes and characteristic words contained by the themes is built with a theme analysis model; virtual concept lattices with the product categories as objects and the themes as properties are constructed with a formal concept analysis model; a comment-quality evaluating model is constructed; the comment data is obtained and subjected to word dividing operation; the divided words are input into the comment-quality evaluating model to conduct quality evaluation of the comment data; the quality evaluation result is output. By means of the evaluating method, the evaluation result of the product comment quality is recommended to a user in an ascending-order mode, and shopping decision of the user can be more objectively assisted. The relativity, the comprehensiveness, the detail performance and the professional performance of a product are evaluated and commented through four quantitative indexes, and the commented quality evaluation result can be obtained and provided for the user to refer.

Description

technical field [0001] The invention relates to the field of electronic commerce, in particular to a method and system for evaluating the quality of text comments in electronic commerce. Background technique [0002] With the acceleration of the development of social informatization, especially the rapid development of the Internet, e-commerce, as a more advanced business model, has risen rapidly in China, but the prevalence of counterfeit and poor-quality goods continues to plague people who shop online. .
