Embodiment Construction

[0017] Some of the proposals of the embodiments of the present invention are based on the inventor's discovery that the reason for the low degree of automation in the prior art lies in the following aspects:

[0018] First of all, both real reviews and fake reviews are written and published by natural persons. In order to make the fake reviews look real, the fake reviewers often consider the content of the reviews in advance and try to make the fake reviews look like real reviews as much as possible. If you simply analyze the content, there is no obvious difference between fake reviews and real reviews, so it is very difficult for machines to detect and identify them. In addition, most product reviews on e-commerce websites are short reviews, which contain relatively little feature information, which further increases the difficulty of automatic identification.

[0019] Secondly, on the basis of analyzing the review content, although the characteristic information of the revie...

Abstract

The invention discloses a method for automatically generating a false comment data set of Chinese commodity, which comprises the following steps: a) reading the comment data collected in advance intoa memory; B) segmenting the comment by using a word segmentation tool to obtain a word sequence representation of the comment text; C) comparing the text similarity between two commodity reviews within a given range to obtain a false commodity review set Rf1; D) executing an associated query on the comments in Rf1 to obtain a product false comment result set R1; E) extracting the name informationof the commentator corresponding to the commodity comment within a given range; (f) analyzing that name of the commentator, finding out the name of a series of commentators conforming to a certain rule characteristic, executing an associated query on the false commentator, and obtaining a product false comment result set R2; G) finally, merging R1 and R2 to obtain the final false comment data setof the commodity. The invention fully automates the detection and identification of the false comment in the commodity comment data and automatically generates the false comment data set of the commodity without manual intervention and labeling.

Description

technical field [0001] The invention relates to a method for automatically generating a data set of false Chinese commodity reviews, which can automatically generate a data set of false commodity reviews based on commodity reviews on domestic e-commerce websites. technical background [0002] At present, major e-commerce (referred to as e-commerce) websites have generated a large amount of review data, coupled with the uneven quality of reviews, it will be a huge challenge for consumers to consult and analyze these data, which has far exceeded The information processing ability of an ordinary consumer. Massive commodity reviews contain not only real and valuable consumer experiences and opinions, but also a considerable number of fake reviews. Behind the false product reviews is the drive of huge commercial interests, which is a typical unfair commercial competition. The proliferation of false product reviews will inevitably seriously affect the healthy development of the ...
