Problems solved by technology

The most unlucky thing is that the base is not stable, it will fall down when you touch it, and the screen will be broken as soon as it falls down. I called the customer service and said that changing the screen is more expensive than changing the TV, so there is no way to repair it.
The 2400 yuan was scrapped within 3 weeks after seeing it, very unhappy!

Embodiment Construction

[0046] Such as figure 1 As shown, the commodity public opinion analysis system based on user evaluation information in the present invention includes:

[0047] (1) Crawler Module (CM for short)

[0048]The main workflow of CM is as follows: (1) start from the specified seed site (starting site), and crawl web pages from the Internet in a breadth-first mode; (2) analyze the page source code for each crawled web page , and analyze it to obtain relevant information in the webpage, such as product features, user evaluations, etc.; (3) classify and write relevant information into the database.

[0049] (2) Data Preprocessing Module (DPM for short)

[0050] (1) DPM first performs word segmentation processing on the user's evaluation text. The word segmentation adopts the Chinese word segmentation algorithm and toolkit developed by the Chinese Academy of Sciences; (2) On the basis of the word segmentation results, DPM uses the association rule mining algorithm Apriori to find high...

Abstract

The invention relates to a data mining and public sentiment analysis technology, and discloses a commodity public sentiment analysis method and system based on user evaluation information so as to quickly and effectively find the emotion of a user on a purchased commodity and carry out commodity public sentiment analysis on the basis of the emotion. The method comprises the following steps: a: carrying out data crawling on an electronic commerce platform to obtain the basic information of a commodity and the commodity evaluation data of a user, carrying out classification writing on the basic information of the commodity and the commodity evaluation data of the user into an evaluation text database; b: preprocessing the commodity evaluation data, and generating a feature vector which can be used for further analysis; c: extracting a typical feature in the feature vector, and analyzing the emotion of the user on the typical feature and the overall mood of the user on a product; and d: carrying out visualized presentation on the analysis result of an emotion analysis module on a Web end. The method is suitable for analyzing the comment data of the electronic commerce platform.

Description

technical field [0001] The invention relates to data mining and public opinion analysis technology, in particular to a commodity public opinion analysis method and system based on user evaluation information. Background technique [0002] In recent years, e-commerce has developed rapidly, and people are increasingly relying on e-commerce platforms such as JD.com, Tmall, and Taobao for shopping. On these e-commerce platforms, users can not only learn about product information in detail, but also learn more about the effect of the product through the evaluation of users who have purchased it. On the other hand, since it is difficult for merchants to collect consumer evaluation information on products sold offline, analyzing user evaluation information on products on e-commerce platforms is an important way to understand product public opinion, which is of great value to both merchants and users. [0003] For example: the following is the user evaluation data of a certain bran...
