In the prior art, the method for determining and adjusting the priority score of the candidate item usually depends on the user data or the personalized behavior data of the user collected in a historical time period to obtain the initial priority score of the candidate item, and then relevant personnel manually adjust the initial priority score of part of the candidate items according to actual demand, experience and strategy to obtain the target priority score of the candidate item. However, the process of manually adjusting the initial priority score of part of the candidate items is tedious and time-consuming, and is easily affected by subjective judgment and lacks objective basis.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort also belong to the protection scope of the present application.

[0015] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or server including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0016] The embodiments of the present application provide a candidate item priority score adjustment method for civil aviation, which comprises the following steps, as shown in the figure. Figure 1 S1, for each influencing factor, if the first target user data corresponding to the influencing factor meets the matching condition corresponding to the influencing factor, the influencing factor is taken as the associated factor corresponding to the target user Y to obtain the associated factor set F corresponding to Y.

[0017] Specifically, the influencing factor is a factor affecting the push order of related information of the candidate item, for example: hotel preference, car preference, bad weather, browsing preference, ticket preference, evening peak, flight itinerary containing car top 10 cities, etc.

[0018] Specifically, the candidate item is an item that may be recommended or displayed to the user, for example: commodity, article, video, service, etc. ​

[0019] Specifically, the first target user data is obtained based on a data acquisition rule corresponding to a matching condition of the influence factor.

[0020] Specifically, the first target user data is obtained based on a data acquisition rule corresponding to a matching condition of the influence factor, and specifically includes: For each influence factor, the first target user data corresponding to the influence factor is obtained from all data related to Y according to the data acquisition rule corresponding to the matching condition of the influence factor.

[0021] Specifically, the influence factor, the matching condition corresponding to the influence factor, and the data acquisition rule corresponding to the matching condition are stored in a first data configuration table corresponding to the influence factor. The first data configuration table is a configuration table pre-set by a person skilled in the art according to actual needs, and includes each influence factor, each matching condition corresponding to each influence factor, and a data acquisition rule corresponding to each matching condition. For example, the influence factor is adverse conditions, the matching condition corresponding to the influence factor is that the current weather type is any one of snow, freezing, low temperature, gale, blowing sand, and heavy rain, and the data acquisition rule corresponding to the matching condition is to obtain the weather type of the arrival place of the current trip at the trip arrival time point.

[0022] In this embodiment, not all influence factors will affect the priority of the candidate. For example, the influence factor is adverse weather, but the departure place, arrival place, and passing place of the current trip of the target user do not have adverse weather, so the influence factor will not affect the priority of the candidate. Through the above steps, only when the first target user data meets the matching condition corresponding to the influence factor, the influence factor is used as the associated factor, which can avoid the interference of irrelevant factors.

[0023] S2, obtain a target push score matrix D corresponding to Y. The element on the ith row and jth column in D is the target push score of the ith influence factor to the jth candidate; 1≤i≤m; 1≤j≤n; m is the number of influence factors; n is the number of candidates.

[0024] S3, for each candidate, the sum of the target push scores of all associated factors in F to the candidate is added to obtain the priority score corresponding to the candidate.

[0025] In one specific embodiment, the larger the priority score of the candidate, the higher the candidate priority corresponding to the candidate.

[0026] Further, the candidate priority is used to determine the push order of the related information of the candidate. The related information of the candidate with high candidate priority is preferentially pushed to M.

[0027] S4. For each of the plurality of candidate adjustment rules, obtain a data set corresponding to the candidate adjustment rule, the data set comprising a question text, at least one influencing factor, at least one candidate item, and a score adjustment manner.

[0028] Specifically, the candidate adjustment rule is determined by a person skilled in the art according to actual needs, for example, a ride service enhancement recommendation rule.

[0029] Specifically, the question text comprises an inquiry text, and the inquiry text is a text for clarifying a decision target and is set by a person skilled in the art according to the candidate adjustment rule, for example, when the candidate adjustment rule is a ride service enhancement recommendation rule, the inquiry included in the question text is whether to adjust the priority score of the candidate item related to the ride service.

[0030] Specifically, the question text further comprises a prompt text, and the prompt text is used to guide the large language model to obtain information related to the decision target corresponding to the inquiry text, to help the large language model understand which external data should be collected for auxiliary judgment, for example, please consider the current user's geographic location, local ride policies, whether there are major events or holidays, and other factors to comprehensively determine whether the priority score of the candidate item related to the ride service needs to be enhanced.

[0031] Specifically, after receiving the question text, the large language model automatically calls external data sources such as weather APIs, map APIs, and local databases to integrate and infer information and output a decision result corresponding to the question text.

[0032] Further, the corresponding relationship between the candidate adjustment rule and the influencing factor and the corresponding relationship between the candidate adjustment rule and the candidate item are determined by a person skilled in the art according to actual needs, for example, when the candidate adjustment rule is a ride service enhancement recommendation rule, the influencing factor corresponding to the candidate adjustment rule is a flight itinerary containing top 10 cities for ride and evening peak, and the candidate item corresponding to the candidate adjustment rule is a vehicle reservation service, real-time traffic information push service, and carpooling service.

[0033] Further, the score adjustment manner corresponding to the candidate adjustment rule is an adjustment manner set by a person skilled in the art according to the candidate adjustment rule, for example, when the candidate adjustment rule is a ride service enhancement recommendation rule, the score adjustment manner corresponding to the candidate adjustment rule is to adjust the priority score to 100, to adjust the priority score to 90, and the like.

[0034] S5, for each candidate adjustment rule, if all influencing factors corresponding to the candidate adjustment rule are included in F, input the problem text corresponding to the candidate adjustment rule into the large language model to obtain a decision result J corresponding to the problem text.

[0035] S6, if J is a first type of result, adjust the priority score corresponding to all candidate items corresponding to the candidate adjustment rule according to the score adjustment mode corresponding to the candidate adjustment rule corresponding to J to obtain a target priority score corresponding to each candidate item; the first type of result indicates that the priority of the candidate item corresponding to the candidate adjustment rule needs to be adjusted.

[0036] Specifically, the decision result also includes a second type of result, and the second type of result indicates that the priority of the candidate item corresponding to the candidate adjustment rule does not need to be adjusted.

[0037] Specifically, the larger the target priority score of the candidate item is, the higher the priority of the candidate item corresponding to the candidate item is.

[0038] Through the above steps, for each influencing factor, if the first target user data corresponding to the influencing factor satisfies the matching condition corresponding to the influencing factor, the influencing factor is taken as an associated factor corresponding to the target user to obtain an associated factor set corresponding to the target user; a target push score matrix corresponding to the target user is obtained; for each candidate item, the sum of the target push scores of all associated factors in the associated factor set on the candidate item is taken as the priority score corresponding to the candidate item; a data set corresponding to the candidate adjustment rule is obtained, the data set includes a problem text, at least one influencing factor, at least one candidate item, and a score adjustment mode; for each candidate adjustment rule, if all influencing factors corresponding to the candidate adjustment rule are included in the associated factor set, input the problem text corresponding to the candidate adjustment rule into the large language model to obtain a decision result corresponding to the problem text; if the decision result is a first type of result, adjust the priority score corresponding to all candidate items corresponding to the candidate adjustment rule according to the score adjustment mode corresponding to the candidate adjustment rule corresponding to the decision result to obtain a target priority score corresponding to each candidate item; only when the first target user data satisfies the matching condition corresponding to the influencing factor, the influencing factor is taken as the associated factor, which can avoid the interference of irrelevant factors; the priority score corresponding to the candidate item is obtained based on the target push score of the associated factor on the candidate item, the adjustment of the priority score is realized through the large language model, the automatic and intelligent adjustment of the priority score of the candidate item is realized, the accuracy of the target priority score is improved, the artificial maintenance cost is effectively reduced, and the data processing efficiency is significantly improved.

[0039] Specifically, the following substeps are included in step S2: S21, obtain a basic push score matrix A from a historical data set L; an element a on an i-th row and a j-th column in A ij is the i-th influencing factor X i is the j-th candidate H j ; L includes all data related to each candidate collected in a historical time period, such as clicks, browsing, collection, purchase, rating, search, behavior occurrence time, geographic location, device type, network environment, age, gender, occupation, likes, collection, etc.

[0040] Specifically, -10≤a ij ≤10.

[0041] Further, the larger a ij is, the greater the influence of X i on H j .

[0042] Specifically, the end time point of the historical time period is earlier than the current time point, and the length of the historical time period is a preset first length.

[0043] Specifically, step S21 includes steps S211-S212 as follows: S211, input the historical data set into a g-th preset recommendation model to obtain an initial push score W i of X j on H g , 1≤g≤h, h is the number of preset recommendation models. ij

[0044] Specifically, -10≤W g ij ≤10.

[0045] Specifically, the preset recommendation model is a recommendation model determined in advance from existing recommendation models, and different preset recommendation models use different recommendation algorithms, such as a content-based preset recommendation model, a collaborative filtering-based recommendation model, and a rule-based recommendation model.

[0046] S212, obtain a g ij based on W ij , a ij satisfies the following condition: a ij =∑ h g=1 (V g ×W g ij ), V g is a preset importance weight corresponding to the g-th preset recommendation model.

[0047] Specifically, ∑ h g=1 V g = 1.

[0048] Through the above steps, the initial push score is obtained according to the historical data set and the preset recommendation model, and the basic push score is obtained based on the preset importance weight corresponding to the recommendation model and the initial push score. Multi-model fusion avoids the deviation of a single model, and is beneficial to improve the accuracy of the obtained basic push score.

[0049] In one specific embodiment, a person skilled in the art can obtain the basic push score of each influencing factor on each candidate item in other ways, for example: setting the basic push score of each influencing factor on each candidate item according to experience, system prior knowledge or expert knowledge of an expert.

[0050] S22, obtaining a value adjustment weight matrix C corresponding to Y according to a second target user data set corresponding to the preset behavior item, a judgment condition corresponding to the preset behavior item and a user tag corresponding to Y; an element c ij for a ij corresponding value adjustment weight; the second target user data set includes n second target user data corresponding to the candidate item one by one.

[0051] Specifically, the second target user data is obtained based on a data acquisition rule corresponding to the preset behavior item.

[0052] Specifically, 0 ≤ c ij ≤ 10.

[0053] Specifically, the preset behavior item and the judgment condition corresponding to the preset behavior item are behavior items and judgment conditions pre-set by a person skilled in the art according to actual needs, for example: the preset behavior item is exposure, and the judgment condition corresponding to the preset behavior item is: no click for ten times of exposure, no click for five times of exposure; or the preset behavior item is a first exposure click ratio and a second exposure click ratio, the judgment condition corresponding to the first exposure click ratio is: the ratio of the number of exposures to the number of clicks is 0.3-0.5, and the judgment condition corresponding to the second exposure click ratio is: the ratio of the number of exposures to the number of clicks is 0.6-0.8.

[0054] Further, the number of preset behavior items is not less than 1.

[0055] Specifically, the number of judgment conditions corresponding to the preset behavior item is not less than 1.

[0056] Specifically, the number of user tags corresponding to Y is not less than 1.

[0057] Specifically, the second target user data is obtained based on a data acquisition rule corresponding to the preset behavior item, and specifically includes the following steps S01-S02. S01, for each preset behavior item, obtain a data acquisition time period corresponding to the preset behavior item, the end time point of the data acquisition time period is the current time point, and the length of the data acquisition time period is a preset length corresponding to the preset behavior item.

[0058] Preferably, the end time point of the historical time period is earlier than the start time point of the data acquisition time period corresponding to any one of the preset behavior items.

[0059] S02, according to the data acquisition rule corresponding to the preset behavior item, from all the data collected in the data acquisition time period corresponding to the preset behavior item and Y and H j with an association relationship, obtain the second target user data corresponding to H j in the second target user data set corresponding to the preset behavior item.

[0060] Specifically, the data acquisition rule corresponding to the preset behavior item is stored in the second data configuration table corresponding to the preset behavior item. The second data configuration table is a configuration table pre-set by a person skilled in the art according to actual needs, including each preset behavior item and the data acquisition rule corresponding to each preset behavior item.

[0061] Through the above steps, the data acquisition time period corresponding to each preset behavior item is obtained, and the second target user data corresponding to the preset behavior item is obtained based on the data acquisition time period and the data acquisition rule corresponding to the preset behavior item. The irrelevant or invalid data can be filtered out, and the waste of resources can be avoided.

[0062] S23, according to A and C, obtain D, wherein the element d ij on the i-th row and j-th column in D satisfies the following conditions: d ij =a ij ×c ij .

[0063] Specifically, the candidate item priority obtained by statistical analysis based on the user behavior data of all users in the historical time period has globality and can reflect the overall popular trend, but ignores the individual differences between users, making it difficult to realize personalized recommendation; based on the personalized historical behavior data of the target user, the preference intensity of each candidate item is predicted through collaborative filtering or deep learning model, which can generate more personalized recommendation results; however, due to the sparseness of the personalized behavior data of the target user, the priority difference between different users is small, which affects the discrimination and accuracy of the recommendation results.

[0064] By the above steps, first, the basic push score matrix is obtained according to the historical data set; for each influencing factor, if the first target user data corresponding to the influencing factor satisfies the matching condition corresponding to the influencing factor, the influencing factor is taken as the associated factor corresponding to the target user to obtain the associated factor set corresponding to the target user; the influence of irrelevant influencing factors is avoided; the score adjustment weight matrix corresponding to the target user is obtained according to the second target user data set corresponding to the preset behavior item, the judgment condition corresponding to the preset behavior item, and the user label corresponding to the target user; the target push score matrix corresponding to the target user is obtained according to the basic push score matrix and the score adjustment weight matrix corresponding to the target user, and the target push score matrix includes the target push score of each influencing factor to each candidate item; the basic push score matrix is modified in combination with the score adjustment weight matrix corresponding to the target user, and the dynamic weight matrix and the multi-source data fusion mechanism are used to obtain the target push score matrix corresponding to the target user; it is beneficial to improve the discrimination and accuracy of the target push score matrix; further, the sum of the target push scores of all associated factors in the associated factor set to the candidate item is taken as the priority score corresponding to the candidate item; while retaining the global statistical advantage, the personalization degree and the discrimination of the push are significantly improved, the discrimination and accuracy of the priority of the candidate item corresponding to different users are enhanced, and further, it is beneficial to improve the discrimination and accuracy of the recommendation result.

[0065] Specifically, in step S22, the following steps are included: S221, for each preset behavior item, if the second target user data corresponding to the preset behavior item in the second target user data set satisfies the judgment condition corresponding to the preset behavior item, the basic adjustment weight corresponding to the basic push score of each influencing factor to H j is updated according to the weight update rule corresponding to the judgment condition, so that E is updated; E is a basic adjustment matrix, the element on the i-th row and the j-th column in E is a j corresponding basic adjustment weight, and the initial value of the basic adjustment weight is 1. ij S222, for each preset behavior item, if the second target user data corresponding to the preset behavior item in the second target user data set does not satisfy the judgment condition corresponding to the preset behavior item, the basic adjustment weight corresponding to the basic push score of each influencing factor to H j is updated according to the weight update rule corresponding to the judgment condition, so that E is updated; E is a basic adjustment matrix, the element on the i-th row and the j-th column in E is a j corresponding basic adjustment weight, and the initial value of the basic adjustment weight is 1.

[0066] Specifically, the weight update rule corresponding to the judgment condition is an update rule pre-set by a person skilled in the art according to actual needs, for example: multiplied by 0.2; multiplied by 6; multiplied by 3; multiplied by 0.5; added by 2; added by 5, subtracted by 2; and details are not described here.

[0067] Specifically, each update of the basic adjustment weight is based on the latest basic adjustment weight obtained from the previous update. According to the priority or execution order of the preset behavior items, the basic adjustment weights corresponding to the basic push scores of the candidate items of each influencing factor corresponding to the preset behavior item are iteratively adjusted in turn to ensure that the update process is timely and continuous; the priority or execution order of the preset behavior items are predetermined by technical personnel in this field according to actual needs and will not be repeated here.

[0068] Specifically, the corresponding relationship between the preset behavior items and the influencing factors is predetermined by those skilled in the art according to actual needs and will not be elaborated here.

[0069] S222, after all updates, E is used as the first adjustment matrix G corresponding to M; the element in the i-th row and j-th column of G is a ij The corresponding first adjustment weight.

[0070] S223: Determine, based on the data validity judgment condition corresponding to the preset behavior item, whether each second target user data corresponding to the preset behavior item is valid data.

[0071] Specifically, the data validity judgment condition corresponding to the preset behavior item is a condition pre-set by technical personnel in this field according to actual needs for judging whether the data is valid. For example: the preset behavior item is exposure, and the data validity judgment corresponding to the preset behavior item is that the exposure duration is greater than the preset minimum exposure duration; if the data in the second target user data corresponding to the preset behavior item indicates that the exposure duration is not greater than the preset minimum exposure duration, then the second target user data is determined to be invalid data; if the data in the second target user data corresponding to the preset behavior item indicates that the exposure duration is greater than the preset minimum exposure duration, then the second target user data is determined to be valid data.

[0072] S224、For H j , if the second target user data corresponding to all preset behavior items are concentrated, and H j The corresponding second target user data are all invalid data, then determine H j Data label H_G in G j is invalid; otherwise, determine H_G j is valid.

[0073] S225, according to G, H_G j Get the user tag C corresponding to Y.

[0074] In the embodiment, when the target user is a new user or the target user unintentionally clicks or swipes some content, partial invalid data can be generated; through the above steps, whether the second target user data is valid data is determined according to the data validity judgment condition corresponding to the preset behavior item, if all the second target user data corresponding to the preset behavior items are invalid data, then the first adjustment weight corresponding to each influence factor on the basis of the push score of the candidate item is also invalid, therefore, it is determined that the data label of the candidate item in the first adjustment weight matrix is invalid, otherwise, it is determined that the data label of the candidate item in the first adjustment weight matrix is valid, the score adjustment weight matrix corresponding to the target user is obtained according to the data label of the candidate item in the first adjustment weight matrix, which is beneficial to improve the accuracy of the score adjustment weight matrix.

[0075] Specifically, the step S225 comprises the following steps: S100, when at least α candidate items in G have valid data labels and not all candidate items in G have valid data labels, if H_G j is invalid, it is determined that H j is the first candidate item; if H_G j is valid, it is determined that H j is the second candidate item; to obtain the first candidate item list L=(L1, L2, …, L k , …, L t ) and the second candidate item list P=(P1, P2, …, P y , …, P q ); α is a preset number of valid items; L k is the kth first candidate item, 1≤k≤t, t is the number of first candidate items, P y is the yth second candidate item, 1≤y≤q, q is the number of second candidate items.

[0076] Specifically, 1<α<n.

[0077] Specifically, t+q=n.

[0078] Specifically, in the step S100, if each candidate item in G has a valid data label or an invalid data label, G is taken as R.

[0079] S200, from all the first adjustment matrices corresponding to all other users obtained in a preset time period, L k corresponding first intermediate matrix list Q k =(Q k1 , Q k2 , …, Q kr , …Qks(k) ), Q kr For L k The corresponding r-th first intermediate matrix, 1≤r≤s(k), s(k) is L k The number of corresponding first intermediate matrices; P1, P2, ..., P y ,…,P q and L k In Q kr The data labels in are all valid; it can be understood as: Q kr Belongs to a set constructed by first adjustment matrices corresponding to all other users acquired within a preset time period.

[0080] Specifically, the other user is any user except the target user.

[0081] Specifically, the end time point of the preset time period is the current time point, the duration of the preset time period is the preset second duration, and the preset second duration is smaller than the preset first duration; preferably, the end time point of the preset time period is the current time point.

[0082] S300, if the second intermediate matrix G corresponding to G 0 With Q kr The corresponding third intermediate matrix Q 0 kr The similarity between them is greater than the preset similarity threshold S 0 , then Q kr As L k The corresponding first key matrix to obtain L k The corresponding first key matrix list V k =(V k1 , V k2 ,…,V kz ,…,V ku(k) ), V kz For L k The corresponding z-th first key matrix, 1≤z≤u(k), u(k) is L k The number of the corresponding first key matrix; G 0 and Q 0 kr are all m×q matrices and G 0 The element in row i and column y is X in G i P y The first adjustment weight corresponding to the basic push score, Q 0 kr The element in row i and column y is Q kr Medium X i P yA first adjustment weight corresponding to the basic push score; Those skilled in the art know that any method of obtaining the similarity between two matrices in the prior art falls within the scope of protection of the present invention and will not be described in detail here.

[0083] Specifically, G 0 With Q 0 kr The greater the similarity between G 0 With Q 0 kr The more similar.

[0084] Specifically, 0.8≤S 0 ≤1.

[0085] S400, V k1 , V k2 ,…,V kz ,…,V ku(k) Medium X i To L k The weighted average of the first adjustment weights corresponding to the basic push scores is used as the X i To L k The first adjustment weight corresponding to the basic push score is used to update G and use G after all updates as the second adjustment matrix R corresponding to M.

[0086] S500: Update R according to the user tag corresponding to Y to obtain C.

[0087] By the above steps, when there are at least a candidate whose data label in the first adjustment weight matrix corresponding to the target user is valid and not all candidates whose data labels in the first adjustment weight matrix are valid, the first adjustment weight of the target user can be updated according to the first adjustment weight corresponding to the other users, the candidate whose data label in the first adjustment weight matrix corresponding to the target user is invalid is taken as the first candidate, the candidate whose data label in the second adjustment weight matrix corresponding to the target user is valid is taken as the second candidate, for each first candidate, a first intermediate matrix in which the first candidate and all second candidates have valid data labels is screened out from the first adjustment matrix corresponding to the other users, a first key matrix in which the data label of the first candidate is valid and similar to the first adjustment matrix corresponding to the target user is screened out according to the similarity between the second intermediate matrix and the third intermediate matrix, and the first adjustment weight corresponding to the basic push score of the candidate of each influencing factor in the first key matrix is used to iteratively update the first adjustment weight corresponding to the basic push score of the candidate of each influencing factor in the first adjustment weight matrix corresponding to the target user; and the first adjustment weight matrix after all updates is taken as the second adjustment weight matrix corresponding to the target user.
