The object may be a dish, or may be other types of goods, or services. The different dimensions may include a first-level dimension or a sum of the first-level dimension and a second-level dimension, the second-level dimension is a sub-dimension corresponding to the first-level dimension, the first-level dimension may include dimensions such as object attributes, user evaluation, user behaviors and list ranking, and the second-level dimension corresponding to the object attributes specifically includes each attribute tag of the object.
For example, the object is specifically a dish, and if the primary dimension corresponding to the dish is the attribute of the dish, the secondary dimension corresponding to the dish includes the quality, heat, raw materials, belonging cuisine, making mode, taste and the like corresponding to the dish; the secondary dimensionalities corresponding to the user behaviors specifically comprise ordering behaviors, favorable behaviors, browsing behaviors and the like of the user; the second-level dimensions corresponding to the list ranking specifically include dimensions such as area list data and in-store list data, and the next-level dimensions corresponding to the area list data specifically include sales ranking list, popularity promotion ranking list, good-evaluation ranking list and the like corresponding to the object.
For this embodiment, when a user browses an object at a client or the client recommends an object to the user, a recommendation corresponding to the object is generated and displayed to the user, so that the user can quickly match a desired object according to the recommendation, and the selection rate of the object is improved.
Wherein the historical associated data may include: the behavior data of the user between the user and the object in different dimensions, the behavior data of the crowd to which the user belongs between the user and the object in different dimensions, the behavior data of the user between the user and the same kind of object in different dimensions, the behavior data of the crowd to which the user belongs between the user and the same kind of object in different dimensions, and the like. The behavior data may specifically include purchase adding behavior data, purchase resuming behavior data, order placing behavior data, click behavior data, and the like of the user, and the association data between the user and the object in different dimensions can be determined according to the behavior data.
For example, the object may be dishes, and when dish recommendation is performed for the user, historical association data between the user and dishes marked with dish attributes, user evaluations, user behaviors and a list ranking data recommendation are collected respectively. Particularly, when historical association data between the user and the dishes marked with the dish attribute recommenders is collected, the dish purchasing behavior data, the dish repurchasing behavior data, the ordering behavior data and the clicking behavior data of the user aiming at the dishes marked with the dish attribute recommenders can be firstly collected, then the crowd to which the user belongs is determined, the purchasing behavior data, the repurchasing behavior data, the ordering behavior data and the clicking behavior data of the crowd aiming at the dishes marked with the dish attribute recommenders are collected, and finally, collecting the purchase adding behavior data, the purchase repeating behavior data, the order placing behavior data and the click behavior data of the crowd aiming at the type of the dish marked with the dish attribute recommending language.
According to the collected behavior data, historical association data between the user and dishes marked with dish attribute recommenders can be determined, and further according to the mode, historical association data between the user and dishes marked with user evaluation recommenders, historical association data between the user and dishes marked with user behavior recommenders, and historical association data between the user and dishes marked with list ranking data recommenders can be respectively determined, so that association weights between the user and different-dimension recommenders of the dishes can be determined according to the historical association data.
And 102, determining the association weight between the user and the recommendation words of different dimensions of the object according to the historical association data.
For this embodiment, in order to generate a recommended language that matches the user best and ensure the degree of association between the user and the generated recommended language, it is necessary to calculate the association weights between the user and the recommended languages of different dimensions of the object.
Specifically, behavior data of a user between objects and different dimensions are collected, behavior data of a crowd to which the user belongs between objects and different dimensions, behavior data of the user between the user and the same kind of objects and behavior data of the crowd to which the user belongs between the user and the same kind of objects and different dimensions are collected, association weights corresponding to the behavior data are determined according to the size of the collected behavior data, and the association weights corresponding to the behavior data are added to obtain association weights between recommenders of the user and the objects in different dimensions.
For example, when determining the association weight between the user and the user behavior recommendation language of the dish, first, the association weight corresponding to the first behavior data is determined according to the size of the first behavior data between the user and the dish marked with the user behavior recommendation language.
Specifically, the association weight corresponding to the first behavior data may be determined according to the data range in which the first behavior data is located, for example, when the first behavior data is greater than 0 and less than 10, the association weight corresponding to the first behavior data is determined to be 1; when the first behavior data is greater than or equal to 10 and smaller than 20, determining that the associated weight corresponding to the first behavior data is 2; and when the first behavior data is more than or equal to 20 and less than 30, determining that the association weight corresponding to the first behavior data is 3, and if the accumulated sum of the purchase adding behavior times, the purchase repurchasing behavior times, the order placing behavior times and the click behavior times of the user in the collected first behavior data is 25, determining that the association weight corresponding to the first behavior data is 3. Similarly, the association weight corresponding to the second behavior data can be determined according to the size of the second behavior data between the crowd to which the user belongs and the dishes marked with the user behavior recommendation, then the association weight corresponding to the third behavior data is determined according to the size of the third behavior data between the user and the similar dishes marked with the user behavior recommendation, finally the association weight corresponding to the fourth behavior data is determined according to the size of the fourth behavior data between the crowd to which the user belongs and the similar dishes marked with the user behavior recommendation, and the association weights corresponding to the behavior data are added to obtain the association weight between the user behavior recommendations of the user and the dishes.
Therefore, the association weight between the user and the recommendation in different dimensions of the object can be determined according to the above mode, so that the target dimension which is most matched with the user is determined according to the association weight, and the generated recommendation in the target dimension is most suitable for the user and is closely associated with the user.
And 103, acquiring a target dimension of which the associated weight meets a preset condition.
For this embodiment, after calculating the association weights between the user and the different-dimension recommenders of the object, the association weights may be sorted according to the calculated association weights, a dimension corresponding to an association weight with a ranking within a preset ranking range is determined as a target dimension, a dimension corresponding to an association weight with a top ranking may also be determined as a target dimension, a dimension corresponding to an association weight with an association weight within a preset weight range may also be determined as a target dimension, and a specific manner for determining a target dimension is not specifically limited in this embodiment.
And 104, generating a recommendation of the object for the user according to the target dimension.
For the embodiment, after the primary target dimension matched with the user is determined, the secondary target dimension matched with the user is continuously determined on the basis of the primary target dimension. Specifically, historical associated data of a user and an object under different secondary dimensions are collected, associated weights between the user and different secondary dimension recommenders of the object are determined according to the historical associated data, a secondary target dimension with the associated weights meeting preset conditions is obtained, and the recommenders of the object are generated for the user according to the secondary target dimension.
For example, the primary target dimension may be a user behavior, the secondary dimension corresponding to the user behavior includes a placing behavior, a favorable behavior and a browsing behavior of the user, and historical association data between the user and an object marked with a placing behavior recommendation, historical association data between the user and an object marked with a favorable recommendation and historical association data between the user and an object marked with a browsing behavior recommendation are collected respectively.
The historical associated data specifically includes: behavior data of the user between the user and the object under different secondary dimensions, and behavior data of the crowd to which the user belongs between the user and the object under different secondary dimensions; the method comprises the steps that behavior data of a user between the user and an object of the type under different secondary dimensions and behavior data of a crowd to which the user belongs between the user and the object of the type under different secondary dimensions are determined, association weights between the user and recommenders of the object of the type under different secondary dimensions are further determined according to the behavior data, a secondary target dimension with the association weights meeting preset conditions is determined, the determination process of the secondary target dimension is the same as the determination process of the primary dimension, and finally, recommenders are generated for the user according to the determined secondary target dimension. Therefore, for the same object, the recommended words seen by different users are different, and the generated recommended words and the users can be guaranteed to have higher matching degree and relevance degree.
In the process of generating the recommended words according to the secondary target dimensions, the recommended words corresponding to different secondary target dimensions are generated in different modes. For example, if the secondary target dimension is a dish raw material, the dish attribute information recorded by the merchant is directly obtained, and the raw material information in the dish attribute information is extracted and displayed to the user as a recommendation.
For another example, if the secondary target dimension is favorable behavior, obtaining comment information for the dish, determining favorable information of the user by positioning the associated words, accumulating the times of the favorable information, and generating a user behavior recommendation for the dish for the user according to the accumulated result and a specific grammar model.
For another example, if the secondary target dimension is user evaluation, obtaining comment information for the dish, and filtering and recombining the comment information to generate a user evaluation recommendation for the dish for the user.
For another example, if the secondary target dimension is the area list data, the area sales ranking, the area popularity surge ranking and the area good rating ranking corresponding to the dish can be counted, and the area list data recommendation for the dish is generated for the user according to the counting result and the specific grammar model.
Compared with the current mode of generating the recommendation according to the description provided by the object publisher, the method for generating the recommendation provided by the embodiment collects historical associated data between the user and the object in different dimensions; determining association weights between the user and different dimensionality recommenders of the object according to the historical association data; meanwhile, acquiring a target dimension of which the associated weight meets a preset condition; and finally, generating the recommended words of the objects for the users according to the target dimensions, so that the recommended words under the target dimensions matched with the users can be generated by collecting historical associated data of the users under different dimensions and the objects, the generated recommended words can be ensured to be closely associated with the users, the recommended words are more suitable for the users, the attraction of the objects to the users is increased, and the selection rate of the objects is improved.
Further, as a refinement and an extension of the specific implementation of the above embodiment, another recommendation generation method is provided, as shown in fig. 2, the method includes:
For the present embodiment, in order to determine a target dimension that is most matched with an object, historical association data between a user and the object in different dimensions needs to be collected, and as an optional implementation manner, for a collection process of the historical association data, step 201 specifically includes: collecting first behavior data between the user and the object in different dimensions; determining a target crowd to which the user belongs, and collecting second behavior data of the target crowd and the object under different dimensions; determining a similar object corresponding to the object, and collecting third behavior data of the user and the similar object in different dimensions, and fourth behavior data of the target crowd and the similar object in different dimensions; determining the first behavior data, and/or the second behavior data, and/or the third behavior data, and/or the fourth behavior data as the history correlation data.
For example, different dimensions are respectively user behavior and list ranking data, historical association data between the user and dishes marked with user behavior recommenders and historical association data between the user and dishes marked with list ranking data recommenders are collected. Specifically, when historical association data between a user and dishes marked with user behavior recommenders is collected, first behavior data of the user for dishes marked with the user behavior recommenders is collected, second behavior data of people to which the user belongs for dishes marked with the user behavior recommenders is collected, third behavior data of the user for dishes marked with the user behavior recommenders is collected, fourth behavior data of people to which the user belongs for dishes marked with the user behavior recommenders is collected, the first behavior data, the second behavior data, the third behavior data and the fourth behavior data respectively comprise purchase adding behavior data, purchase repeating behavior data, order placing behavior data and click behavior data, and historical association data between the user and the dishes marked with the user behavior recommenders is determined according to at least one of the first behavior data, the second behavior data, the third behavior data and the fourth behavior data, similarly, historical association data between the user and the dishes marked with the list ranking data can be determined in the above mode, so that association weights between the user and different-dimension recommenders of the dishes are determined according to the historical association data.

For this embodiment, in order to determine the associated weights between the user and the recommenders for different dimensions of the object, step 202 specifically includes: determining associated weights corresponding to the first behavior data, and/or the second behavior data, and/or the third behavior data, and/or the fourth behavior data, respectively; and adding the associated weights respectively corresponding to the first behavior data, the second behavior data, the third behavior data and/or the fourth behavior data to obtain the associated weights between the user and the different-dimension recommenders of the object. When determining the association weights corresponding to the different-dimension recommenders, the association weights corresponding to the different-dimension recommenders may be determined according to the association weight corresponding to any behavior data, or the association weights corresponding to any several behavior data in the first behavior data, the second behavior data, the third behavior data, and the fourth behavior data may be added to obtain the association weights corresponding to the different-dimension recommenders.
For example, when determining the association weight between the user and the list ranking data recommender of the dish, first, the association weight corresponding to the first behavior data is determined according to the size of the first behavior data between the user and the dish marked with the area list ranking data recommender. Specifically, the association weight corresponding to the first behavior data may be determined according to the data range in which the first behavior data is located, for example, when the first behavior data is greater than 0 and less than 10, the association weight corresponding to the first behavior data is determined to be 1; when the first behavior data is greater than or equal to 10 and smaller than 20, determining that the associated weight corresponding to the first behavior data is 2; when the first behavior data is more than or equal to 20 and less than 30, determining that the associated weight corresponding to the first behavior data is 3, if the accumulated sum of the times of purchase adding behavior, the times of repurchase behavior, the times of order release behavior and the times of click behavior of the users in the collected first behavior data is 25, determining that the associated weight corresponding to the first behavior data is 3, similarly, determining the associated weight corresponding to the second behavior data according to the size of the second behavior data between the crowd to which the users belong and the dishes marked with the regional list data recommenders, then determining the associated weight corresponding to the third behavior data according to the size of the third behavior data between the users and the similar dishes marked with the regional list data recommenders, and finally determining the associated weight corresponding to the fourth behavior data according to the size of the fourth behavior data between the crowd to which the users belong and the similar dishes marked with the regional list data recommenders, and adding the associated weights corresponding to the behavior data to obtain the associated weight between the user and the regional list data recommendation of the dishes.
And 203, acquiring a target dimension of which the associated weight meets a preset condition.
For the embodiment, if the user is a new user, the historical associated data of the user cannot be collected, so that the target dimension matched with the user cannot be determined according to the historical associated data, and in order to generate corresponding recommenders for the new user as well, when the target dimension is determined, the target dimension matched with the user can be determined according to the basis weights of the object for recommenders with different dimensions, and then the recommenders are generated for the new user; if the user is not a new user, jointly determining a target dimension matched with the user according to the calculated association weight and the basis weight, and further generating a corresponding recommended word for the user, based on which step 203 specifically includes: determining the basic weight of the object aiming at the recommendation words with different dimensions; adding the basic weight and the associated weight to obtain a total weight between the user and the recommendation words with different dimensions of the object; and determining the dimension of which the total weight is greater than the preset weight as a target dimension.
Specifically, when determining a target dimension corresponding to a new user, since the historical associated data of the user cannot be collected, historical associated data of the same type of population between the object and the same type of population in different dimensions can be collected, the basic weights of the object for recommenders in different dimensions can be determined according to the historical associated data corresponding to the same type of population, for example, the new user is a fat-reduction user, the historical associated data of the fat-reduction type population between the object and the same type of population in different dimensions is collected, the basic weights of the object for recommenders in different dimensions are determined according to the historical associated data corresponding to the fat-reduction type population, the target dimension with the basic weight meeting preset conditions is obtained, for example, the basic weight corresponding to the ranking data is the largest, the ranking data is determined as the target dimension, and for example, the ranking data and the basic weight corresponding to the user behavior are within a preset weight range, determining the ranking data of the list and the user behavior as target dimensions.
Further, if the user is not a new user, the association weight and the corresponding basis weight may be added to obtain a total weight between the user and the recommendation of the object in different dimensions, for example, the basis weight corresponding to the list ranking data and the association weight between the user and the recommendation of the list ranking data are added to obtain a total weight between the user and the list ranking data, and similarly, the total weight between the user and the user behavior and the total weight between the user and the commodity attribute may be obtained, and the dimension corresponding to the maximum total weight is determined as the target dimension, and the corresponding recommendation is generated for the user according to the target dimension. Therefore, according to the mode, the recommendation language can be generated not only for the old user, but also for the new user.
And 204, generating grammar through a preset recommendation corresponding to the target dimension, and generating the recommendation of the object for the user.
In this embodiment, after the primary target dimension matched with the user is determined, the secondary target dimension matched with the user needs to be continuously determined, and a specific determination process of the secondary target dimension is the same as that of the primary target dimension, and is not repeated again.
In a specific application scenario, if the secondary target dimension includes at least one dimension of a weight, a material, and a taste corresponding to an object, the generating a grammar by using a preset recommendation corresponding to the target dimension to generate a recommendation of the object for the user includes: obtaining raw data of at least one dimension of the weight, the material and the taste; and generating a recommendation corresponding to the object for the user according to the original data.
For example, if the primary target dimension is a dish attribute, and the secondary target dimension is a material corresponding to a dish, dish description information issued by a merchant may be acquired, the dish description information is used as original data, the material corresponding to the dish is extracted from the original data, and a recommendation corresponding to the dish is generated for the user. If the tomato scrambled eggs comprise tomatoes and eggs, the material labels 'tomatoes and eggs' can be displayed to the user as recommenders, furthermore, historical behavior data of the user for the tomato scrambled eggs can be collected, the historical behavior data comprise purchase times, order placing times and click times of the user for the tomato scrambled eggs, and by analyzing the historical behavior data of the user for the tomato scrambled eggs, if it is determined that the purchase times, order placing times and click operations of the user are more frequent when the material label 'tomatoes' is preferentially displayed, which indicates that the user has a higher interest level in the tomatoes, the material label 'tomatoes' can be preferentially displayed to the user, and then the 'eggs' are displayed.

Wherein the pre-set positive word library comprises positive words.
As shown in fig. 3, the secondary target dimension is comment information, the dish is roasted fish with sweet fragrance, comment information related to the roasted fish with sweet fragrance is collected, a preset front lexicon is used for locating front comment words in the comment information, sentences containing the front comment words are proposed, and then the extracted sentences are spliced by using a preset grammar model.
For example, the extracted sentence includes "wonderful roasted fish", "good taste", and "next return", which are composed using a preset grammar model to generate a recommendation "wonderful roasted fish, good taste, and next return" for the user. In addition, the positioned positive comment words can be directly extracted and spliced, for example, the extracted positive comment words comprise 'good words' and 'very tender', and after the comment words are spliced with the name of the dish, a recommendation word 'wonderful roasted fish, very delicious and very tender' is generated for the user. Therefore, the comment information recommendation words can be generated according to the two modes and displayed to the user, so that the user can quickly find the required dishes according to the comment words, and the ordering rate of the dishes is improved.
In a specific application scenario, if the secondary target dimension includes at least one of a placing behavior, a good comment behavior, and a browsing behavior, the generating a grammar by using a preset recommendation corresponding to the target dimension to generate the recommendation of the object for the user includes: counting original data under at least one dimension of ordering behavior, favorable behavior and browsing behavior to obtain a first statistical result corresponding to the object; and generating a recommendation corresponding to the object based on the first statistical result and a first preset grammar model.
