Detailed Description
The present application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present application are shown in the drawings.
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the embodiments of the present application are further described in detail by the following embodiments with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The execution subject of the method embodiment described below may be a commodity price anomaly identification device, which may be implemented as part or all of an electronic device by software, hardware, or a combination of software and hardware. Alternatively, the electronic device may be a smart phone, a tablet computer, an electronic book reader, a vehicle-mounted terminal, or the like. Of course, the electronic device may also be an independent server or a server cluster, and the specific type of the electronic device is not limited in the embodiments of the present application. The following method embodiments are described taking an electronic device as an example of an execution subject.
Fig. 1 is a schematic flow chart of a commodity price anomaly identification method according to an embodiment of the present application. This embodiment relates to a specific process of how the electronic device recognizes whether the current pricing of the target commodity is abnormal.
As shown in fig. 1, the method may include:
s101, responding to pricing instructions for target commodities, and extracting emotion information of brands of the target commodities from the public opinion texts.
Specifically, the public opinion text may be original content of a user in the platform, commodity evaluation information and social platform public opinion text. By way of example, the public opinion text may be forums, microblogs, shopping websites, comments in an e-commerce platform, posts, etc. For example, the public opinion text may be rating data of goods by a user in a shopping network, or the like.
In practical applications, a user (e.g., a seller in a shopping platform) may trigger a pricing instruction through a corresponding control presented in the platform to price a target commodity, where the pricing instruction may include current pricing information of the target commodity by the user. For example, a user may price a certain shoe in a shopping platform.
After receiving the pricing instruction for the target commodity, the electronic device can acquire the public opinion text related to the target commodity and extract emotion information of the commodity brand to which the target commodity belongs from the acquired public opinion text. The public opinion text has entity information and emotion information, the entity information can be commodity names or brands, and the emotion information can represent the characteristics of commodity brands on certain attributes, such as quality, price and the like. In an alternative embodiment, entity words for representing entity information and attribute words for representing emotion information may be determined in public opinion text, so as to obtain emotion information of a commodity brand to which a target commodity belongs. The nearest heat condition of the target commodity can be effectively found through the emotion information, and whether the target commodity has a stir-frying trend or not is further predicted. For example, if the recent heat of the target commodity is found to be high by the emotion information, the suspicion of the target commodity is high, whereas if the heat of the target commodity is found to be not different from the usual heat by the emotion information, the suspicion of the target commodity is low.
S102, acquiring reference price information of the target commodity.
Specifically, a historical transaction log is obtained, and reference price information of the target commodity is extracted from the historical transaction log, wherein the reference price information comprises official suggested price, historical bargain price and historical successful pricing price of the target commodity. By improving the reference basis by taking the reference price information as the current pricing information of the target commodity, whether the current pricing information is abnormal or not can be predicted based on the gap between the current pricing information and the reference price information. For example, if the current pricing information deviates from the reference pricing information more, the higher the likelihood of abnormality of the current pricing information is predicted; conversely, if the current pricing information is offset by the reference pricing information less, the likelihood of abnormality of the current pricing information is predicted to be lower.
S103, identifying whether the current pricing information is abnormal or not according to the reference price information and the emotion information.
After the emotion information of the brand of the target commodity and the reference price information of the target commodity are obtained, comprehensively utilizing the reference price information and the emotion information of the brand of the target commodity to identify whether the current pricing information of the target commodity is abnormal or not. It can be understood that the above-mentioned reference price information is taken as a reference standard, a relatively reasonable price interval of the target commodity is provided, the above-mentioned emotion information can reflect the stir-frying trend of the brand of the target commodity, if the current pricing information deviates from the reference price information of the target commodity and the stir-frying suspicion of the target commodity is predicted to be greater through the emotion information, the current pricing information is more likely to be an abnormal price, otherwise, if the current pricing information deviates from the reference price information of the target commodity and the stir-frying suspicion of the target commodity is predicted to be less through the emotion information, the current pricing information is less likely to be an abnormal price.
Of course, as an alternative embodiment, the reference price information and the emotion information may be set with corresponding weights, and whether the current pricing information of the target commodity is abnormal may be determined by using the reference price information, the emotion information, the weights corresponding to the reference price information, and the weights corresponding to the emotion information.
In the pricing process of the target commodity, the public opinion text issued by the user is fully utilized to mine the emotion information of the commodity brand of the target commodity, whether the target commodity has a suspicion of stir-frying or not is predicted through the emotion information, and the emotion information is taken as one of the characteristics to be added into the abnormality recognition process of the current pricing of the target commodity, so that the recognition result of the abnormality judgment of the current pricing information can be improved.
After the recognition result of the current pricing information is obtained, a corresponding control operation may also be performed according to the recognition result of the current pricing information.
Specifically, when the current pricing information is determined to be an abnormal price, the user may be denied the pricing operation for the target commodity, i.e., the target commodity is not allowed to be priced according to the current pricing information. Further, a prompt may be output to the user that the pricing failed to instruct the user to re-price the target merchandise.
When the current pricing information is determined to be the normal price, the user can agree with the pricing operation of the target commodity, namely, the target commodity is priced according to the current pricing information, and the current pricing information of the target commodity can be displayed, so that the transaction of the subsequent commodity is facilitated. Further, a prompt for successful pricing may also be output to the user.
Corresponding control operation is executed based on the identification result of the current pricing information, so that the accurate prevention and control of abnormal commodity pricing are realized, and the normal transaction order of the platform and the risk of commodity stir-frying prevention are maintained.
According to the commodity price anomaly identification method provided by the embodiment of the application, in response to a pricing instruction aiming at a target commodity, emotion information of a commodity brand to which the target commodity belongs is extracted from a public opinion text, the pricing instruction comprises current pricing information of the target commodity, reference price information of the target commodity is obtained, and whether the current pricing information is abnormal is identified according to the reference price information of the target commodity and the emotion information of the commodity brand to which the target commodity belongs. In the pricing process of the target commodity, the emotion information of the brand of the target commodity and the reference price information of the target commodity, which are included in the public opinion text, are fully utilized, and whether the pricing of the target commodity is suspicious or not can be effectively identified, so that the accuracy of the commodity price anomaly identification result is improved.
In one embodiment, as shown in fig. 2, the extracting, in S101, emotion information of a brand of the target commodity from the public opinion text may include:
s201, obtaining public opinion texts of all social platforms by utilizing a crawler technology.
With the rapid development of internet technology, the internet has become a carrier of a large amount of information, and various information including news, electronic commerce, commodity reviews, etc. can be viewed through the internet, so that crawler technology has been developed. Crawler technology refers to a program or script that automatically crawls information on the internet according to certain rules.
Because various information of the commodity can be distributed on various social platforms, such as forums, microblogs, shopping websites, various electronic commerce platforms and the like, the content of the related commodity information in each social platform can be crawled by adopting a crawler technology, so that a public opinion text is obtained. The social platform comprises an internal platform and an external platform.
S202, preprocessing the public opinion text to obtain the processed public opinion text.
After the public opinion text is obtained, the public opinion text can be cleaned, and some content irrelevant to commercial brands, such as advertisement stickers, non-commercial brand content posts and the like, can be filtered; furthermore, abnormal characters in the public opinion texts can be processed, a data basis is provided for accurate analysis of the follow-up public opinion texts, and influence of irrelevant contents on public opinion analysis results is avoided.
And S203, inputting the processed public opinion text into a pre-trained brand emotion analysis model to obtain emotion information of a commodity brand to which the target commodity included in the public opinion text belongs.
The framework of the brand emotion analysis model can be Bert+softmax and Bert+CRF, bert is a model obtained by pre-training two tasks of 'Fill in the blank task' and 'Next sentence prediction', the output of Bert can be mapped into a label set for labeling problems only by adding a full-connection layer on the basis of Bert and determining the output dimension of the full-connection layer, the output vector of a single token is processed by softmax or CRF, and the numerical value of each dimension represents the probability that the token is a certain label. Wherein CRF is a classical probability map model. That is, the addition of softmax or CRF based on the pre-training model can realize emotion judgment based on the commercial brand in the public opinion text and information labeling of the commercial brand entity. Of course, the brand emotion analysis model may be implemented by other architectures, which are not limited in this embodiment.
Taking a brand emotion analysis model as a Bert+softmax and a Bert+CRF architecture as an example, after a processed public opinion text is obtained, inputting the processed public opinion text into a pre-trained brand emotion analysis model, coding the public opinion text through a Bert module in the brand emotion analysis model to obtain coding vectors corresponding to each token in the public opinion text, and then classifying and mapping the coding vectors through the softmax and the CRF, so that emotion information of a commodity brand to which a target commodity belongs in the public opinion text is extracted.
Optionally, before the crawler technology is used to obtain the public opinion text of each social platform, the brand emotion analysis model may be trained, and specifically, the brand emotion analysis model may be obtained through the following training process:
acquiring a first training data set; the first training data set comprises a plurality of sample public opinion texts and emotion information of commodity brands contained in each sample public opinion text; and training the brand emotion analysis model according to the first training data set.
Specifically, a plurality of sample public opinion texts are obtained, and then commodity brands and corresponding emotion polarities in the sample public opinion texts are marked to obtain emotion information of the commodity brands included in the sample public opinion texts. And then, taking a plurality of sample public opinion texts as input, taking emotion information of commodity brands included in the plurality of sample public opinion texts as expected output, determining actual output corresponding to the plurality of sample public opinion texts through a brand emotion analysis model, determining a loss value of a preset loss function based on the actual output and the expected output, and optimizing parameters of the brand emotion analysis model by using the loss value until the loss value reaches a preset convergence condition and is kept stable, so that a trained brand emotion analysis model is obtained.
Of course, after obtaining a plurality of sample public opinion texts, the sample public opinion texts can be cleaned, and some content irrelevant to commercial brands, such as advertising stickers, non-commercial brand content posts and the like, can be filtered; furthermore, abnormal characters in the sample public opinion text can be processed, and a data basis is provided for training of a subsequent brand emotion analysis model, so that accuracy of the brand emotion analysis model is ensured.
In this embodiment, since the brand emotion analysis model is obtained through training of a large amount of training data, the brand emotion analysis model can better learn the representation of the brand and emotion information of the commodity, and thus, the accuracy of emotion analysis based on the brand of the commodity can be improved by processing the public opinion text of the target commodity through the brand emotion analysis model.
In one embodiment, as shown in fig. 3, the process of S103 may be:
s301, inputting current pricing information, reference price information and emotion information into a pre-trained anomaly detection model to obtain anomaly probability of the current pricing information.
Specifically, the anomaly detection model may be a binary tree model, such as a LightGBM algorithm, an XGBoost algorithm, and the like. The abnormality detection model is trained based on a second training data set. The second training data set includes historical pricing information of a plurality of sample commodities, reference price information, emotion information of commodity brands to which the plurality of sample commodities belong, and tag information of whether the historical pricing information is abnormal.
When the anomaly detection model is trained, historical pricing information, reference price information and emotion information of brands of goods to which the plurality of sample goods belong can be used as inputs, label information of whether the historical pricing information of the plurality of sample goods is abnormal is used as expected output, actual output of whether the historical pricing information of the plurality of sample goods is abnormal is determined through the anomaly detection model, a loss value of a preset loss function is determined based on the actual output and the expected output, parameters of the anomaly detection model are optimized through the loss value until the loss value reaches a preset convergence condition and is kept stable, and therefore the anomaly detection model is obtained.
After the trained anomaly detection model is obtained, the current pricing information, the reference price information and the emotion information of the target commodity can be input into the anomaly detection model, the difference between the current pricing information and the reference price information is analyzed through the anomaly detection model, the emotion information of the commodity brand to which the target commodity belongs is analyzed, whether the target commodity is suspected of being stir-fried or not is predicted, and therefore the anomaly probability of the current pricing information is obtained.
S302, determining whether the abnormal probability of the current pricing information is larger than a preset threshold value.
The preset threshold value can be set based on actual requirements. If the abnormality probability of the current pricing information is greater than the preset threshold, the following S303 is executed, and if the abnormality probability of the current pricing information is less than or equal to the preset threshold, the following S304 is executed.
S303, determining the current pricing information as an abnormal price.
S304, determining the current pricing information as a normal price.
When the current pricing information is determined to be an abnormal price, the pricing operation of the target commodity can be refused, namely the target commodity cannot be priced according to the current pricing information indicated by the user; re-pricing the target commodity may also be indicated. When the current pricing information is determined to be the normal price, the pricing operation of the target commodity can be allowed, namely the target commodity can be priced according to the current pricing information indicated by the user, so that the accurate control of the abnormal commodity pricing operation is realized, and the normal transaction order of the platform is maintained.
In this embodiment, since the anomaly detection model is obtained through training of a large amount of training data, the anomaly detection model can better learn the mapping relationship between each feature and the recognition result, and thus, the accuracy of identifying the anomaly in the price of the commodity can be improved by processing the current pricing information of the target commodity through the anomaly detection model. And the emotion information of the commodity brand of the target commodity is input into the anomaly detection model as a characteristic, and the public opinion text of the target commodity is fully utilized, so that the anomaly detection model can effectively identify whether the pricing of the target commodity is suspicious, and the accuracy of the commodity price anomaly identification result is further improved.
