Embodiment 1

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

[0146] Grab the review data, and classify the review data by commodity category to build product review documents;

[0147] Use the theme analysis model to establish the relationship between commodity categories, themes and the characteristic words contained in the theme;

[0148] Using 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 assessment model;

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

[0151] Input the word segmentation into the comment quality assessment model to assess the quality of comment data;

[0152] Output quality assessment results.

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

[0154] Categorize review data...

Embodiment 2

[0271] The evaluation system for the quality of transaction reviews provided in this embodiment can realize the objective evaluation of the quality of transaction reviews. And it can recommend comments with high evaluation quality to transaction users, so that users can refer to them during transactions.

[0272] The system includes a product review document building module, through which, the preprocessing of the review data captured from the network is completed, that is, the review data is classified according to the product category.

[0273] The system includes a topic analysis module based on review documents, which extracts product review topics by using topic analysis models, and uses these topics to establish associations among commodity categories, topics, and words contained in topics.

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

Embodiment 3

[0277] The method for evaluating the quality of text comments in e-commerce provided in this embodiment is a method for evaluating the quality of the comments themselves. This method will evaluate the quality of the review in terms of the relevance of the review to the product, the comprehensiveness of the review itself, and the professionalism of the reviewer in the field involved in the product. Finally, the larger the value of the comment quality evaluation, the higher the quality of the comment, and the more useful it is for users.

[0278] In the review quality evaluation system provided in this embodiment, the processing flow is as follows: figure 1 As shown, it mainly includes four modules: product review document construction module; topic analysis module based on review documents; virtual concept lattice construction module based on commodity categories and topics; review quality evaluation module based on virtual concept lattice.

[0279] 1) The product review docum...

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. .
