The working principle and the beneficial effects of the technical scheme are as follows:
the preset attribute type-important value library is specifically as follows: databases containing important values corresponding to different attribute types, such as: the attribute type is a lens material provider, the corresponding important value is 95, and the important value represents the influence degree of the attribute type on the lens quality; the preset importance value threshold specifically includes: for example, 75; the preset negative event generation model specifically comprises the following steps: a model generated after learning a record of a large number of artificially created negative events using a machine learning algorithm, the model may generate negative events based on attribute terms, such as: the attribute item is a certain lens material manufacturer, the negative event is the lens material produced by the manufacturer, the quality of the lens is unqualified, and the like, and a first severity value of the negative event is also output, wherein the greater the first severity value is, the more severe the corresponding negative event is; the capture strategy is specifically as follows: for example, web page crawling; the preset capture strategy-capture object library specifically comprises the following steps: data containing capture objects corresponding to different capture strategies, such as: step policy is web page crawling, and the capture objects are a plurality of shot forum websites; the preset confidence threshold specifically comprises: for example, 80; the preset relationship value threshold specifically comprises: for example, 90; the receiving node specifically comprises: a network node, the other side can send the data to the network node, namely finish the data reception; the preset inquiry mode specifically comprises the following steps: for example, whether there is newly received data, if so, please reply; the preset risk characteristic library specifically comprises the following steps: a database containing a plurality of risk features, a risk feature being a feature that may cause a malicious event, such as: the user wants to release false data and suddenly changes identity information (risk characteristics); the preset malicious feature library specifically comprises the following steps: the system comprises a plurality of malicious feature databases, wherein the malicious features are, for example: changing identity information, and checking the released data as false data; the preset range is specifically as follows: a range on the time axis corresponding to a certain length of time (e.g.: 2 days); the preset event determination model specifically includes: the model is generated after learning records for manually judging whether the events comprise certain events by utilizing a machine learning algorithm, and the model can determine whether the events comprise certain events;
when the second evaluation target to be evaluated is screened, it may be determined based on the attribute information of the zoom lens, for example: a manufacturer of production materials of the zoom lens needs to evaluate the contrast when a problem event that the contrast of lens imaging is poor due to material problems occurs; however, how to acquire problem events needs to be solved; extracting a first attribute item (such as a material provider) in attribute information, screening out a second attribute item which has an influence on a quality result based on an important value, generating a negative event corresponding to the second attribute item based on a negative event generation model, and determining whether the negative event occurs; trying to capture a shot quality event (for example, a quality evaluation article published by a certain user in a forum website), if the capture is successful, determining multiple processes in the capture process (for example, process 1, capturing a comment that the user does not "quality" in a manufacturer discussion area, process 2, capturing a homepage of the user and publishing a specific article), where a first capture scene corresponding to the processes is, for example: the process 1 corresponds to a web page of a manufacturer discussion area, and the process 2 corresponds to a web page of a user homepage; acquiring the credibility (webpage credibility) of the first capture scene, and if the credibility is smaller than a credibility threshold, taking the corresponding first capture scene as a second capture scene; trying to acquire an association relationship between a second capture scene and a capture object (for example, the second capture scene belongs to a webpage of the capture object, and the capture object guarantees the webpage to form a guarantee relationship), if the acquisition fails, it is indicated that the second capture scene is not credible (for example, from other forums), if the acquisition succeeds, the relationship (guarantee relationship) is analyzed to acquire a relationship value, and the greater the relationship value is, the greater the guarantee degree of the capture object guaranteeing the relationship is, and the higher the credibility is; some cooperative forums do not allow the party to capture in consideration of privacy security, receiving nodes can be set, and the other party can send the cooperative forums to the party; however, when a third shot quality event is received, the corresponding sender needs to be verified; acquiring a sending record (a record of historically sending data to a plurality of receiving nodes, and the like) of a sender, extracting a plurality of first record items, matching the first characteristics with the second characteristics, determining whether risk characteristics possibly causing malicious events occur, and if so, determining a supplement direction, for example: the third characteristic is that the user changes identity information suddenly, and false data can be uploaded later, and the supplement direction is later; if the supplement direction cannot be determined, the second record item is proved to have a malicious event, the first combination characteristic and the second combination characteristic are respectively combined based on the two conditions and are matched with the fourth characteristic, and whether the malicious event occurs or not is determined; after the lens quality events needing to be removed are removed, determining whether the remaining lens quality events contain corresponding negative events, wherein the larger the content is, the more the evaluation target corresponding to the first attribute item needs to be evaluated;
when the second evaluation target needing to be evaluated is screened from the first evaluation target, the second evaluation target can be determined based on the attribute information of the zoom lens, the setting is reasonable, the efficiency of quality evaluation on the zoom lens is improved, and unnecessary workload is reduced; meanwhile, when the lens quality event is acquired, the incredible lens quality event is eliminated, and the accuracy and the safety of acquisition are guaranteed.
