All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
In addition, the term "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. In this context, unless otherwise specified, the term "/" generally indicates that the associated object is an "or" relationship.
Embodiments of the present application are described in further detail below with reference to the drawings attached hereto.
The embodiment of the application provides a user demand recommendation method, and the main flow of the method is described as follows.
As shown in fig. 1:
step S101: and acquiring user history data in a preset time.
Specifically, the user history data includes a plurality of browsing data, each browsing data includes a commodity category and a style identifier, each browsing data corresponds to browsing a commodity, and each browsing data includes a commodity category and a style identifier. The commodity category indicates the types of commodities including foods, furniture, clothing, etc., and the style identification includes the style of a certain type of commodity, for example, the style of furniture includes new style, mediterranean style, new classical style, european style, japanese style, nordic style, industrial style, post modern style, garden style, modern brief style, etc., and the style of clothing includes fresh wind, leisure wind, sports wind, business wind, brief wind, etc. The preset time is a set time, generally, the user history data of the previous year or the previous two years of the current time is obtained instead of all the user history data, the preference of the user in the last period of time can be analyzed by obtaining the user history data in the preset time, if all the user history data are obtained, the latest preference of the user may be weakened, and a larger error exists in the subsequent analysis result.
Step S102: and determining the category weight and the style weight corresponding to the user history data according to the user history data, a preset style category comparison table and a preset weight calculation rule.
Specifically, the style category comparison table includes all commodity categories, all style identifications, category association degrees among all commodity categories, and style association degrees among all style identifications. And acquiring the style data volume and the category data volume corresponding to the user history data, wherein the style data volume represents the number of different style identifications included in the user history data, and the category data volume represents the number of different commodity categories included in the user history data. For example, the user history data has ten pieces of browsing data, wherein the style with 4 pieces of browsing data is identified as an industrial style, the style with 4 pieces of browsing data is identified as a garden style, the style with 2 pieces of browsing data is identified as an European style, and the style data amount is 3. The category data amount is the same as the style data amount, and will not be described here. And acquiring the total number of styles and the total number of categories in the style category comparison table, wherein the total number of styles represents the number of all the style identifications, and the total number of categories represents the number of all the commodity categories. The above category weight = category data amount/total number of categories; the above style weight=style data amount/style total.
Step S103: based on the feature determining rule, determining a feature style and a feature category according to the commodity category, the style identification and the style category comparison table.
Specifically, according to the user history data and the style category comparison table, the style association degree of the style identifier corresponding to the user history data and other style identifiers and the category association degree of the commodity category corresponding to the user history data and other commodity categories are obtained. The other style identifications include other style identifications in addition to the style identifications appearing in the user history data. The other commodity categories include commodity categories other than those appearing in the user history data. When the style association degree is within the preset association threshold value range, the style concerned by the user and other styles with higher similarity are indicated, and the styles with higher similarity can be recommended to the user, and other styles corresponding to the style association degree are identified as feature styles. When the category association degree is within a preset association threshold value, a user who purchases or pays attention to the commodity category also purchases or pays attention to the commodity corresponding to the commodity category, and other commodity categories corresponding to the category association degree are feature categories.
Step S104: and determining push content and push duty ratio corresponding to the push content according to the category weight, the style weight, the feature style, the feature category and a preset recommendation method, and pushing.
Specifically, the pushing content includes a commodity corresponding to the characteristic style, a commodity corresponding to the characteristic category, a commodity corresponding to the style identification, and a commodity corresponding to the commodity category; determining a user type according to the style weight, the category weight and a preset weight comparison table, wherein the user type represents wide browsing preference or preference concentration of a user; and respectively determining a push duty ratio corresponding to the characteristic category, a push duty ratio corresponding to the characteristic style, a push duty ratio corresponding to the style identification and a push duty ratio corresponding to the commodity category according to the user type and the recommended proportion table, and completing push. The weight comparison table comprises style weights, category weights and user types corresponding to the style weights and the category weights. The recommended proportion table comprises a user type, a push duty ratio corresponding to a characteristic category, a push duty ratio corresponding to a characteristic style, a push duty ratio corresponding to a style identification and a push duty ratio corresponding to a commodity category.
In one example, when both the category weight and the style weight are greater than sixty percent, the user is indicated to be of a type that is relatively broad for both category and style preferences. And carrying the user type into a recommended proportion table to obtain a specific push duty ratio. The specific push duty cycle for this user is: pushing commodities of commodity categories browsed by a user to seventy percent of total push content, namely, pushing proportion corresponding to the commodity categories is seventy percent; pushing commodities of commodity categories which are not browsed by the user to be thirty percent of the total push content, namely, the push proportion corresponding to the characteristic categories is thirty percent; pushing commodities with style marks browsed by a user to seventy percent of total push content, namely, pushing the commodities with style marks corresponding to seventy percent; the commodity pushing of the style identification which is not browsed by the user accounts for thirty percent of the total pushing content, namely the pushing ratio corresponding to the characteristic style is thirty percent.
In another example, when the category weight is greater than seventy percent and the style weight is less than twenty percent, the user is indicated to be of a type that is more extensive for the category and more focused for the style's preference. And carrying the user type into a recommended proportion table to obtain a specific push duty ratio. The specific push duty cycle for this user is: pushing commodities in commodity categories browsed by a user to be fifty percent of the total push content, namely, the push ratio corresponding to the commodity categories is fifty percent; pushing commodities of commodity categories which are not browsed by the user to be fifty percent of the total push content, namely, the push proportion corresponding to the characteristic categories is fifty percent; pushing the commodity with the style identifier browsed by the user to ninety percent of the total push content, namely, enabling the pushing ratio corresponding to the style identifier to be ninety percent; and pushing the commodity which is not browsed by the user and is identified by the style to be ten percent of the total push content, namely, the push ratio corresponding to the characteristic style is ten percent.
It can be understood that each commodity includes a style identification and a commodity category, and when the push of the commodity category is relatively large and the push of the style identification is relatively small, the commodity category is shown to push a plurality of different commodities, but the styles are relatively concentrated. For example, the recommended commodity categories include clothing, furniture, cloth, and ornaments. The recommended commercial styles all tend to be consistent, for example, both pink girl winds or both black and white and gray conciseness winds.
The user demand recommendation method further comprises the following steps: and acquiring the characteristic browsing data and adjusting the push content and the push duty ratio corresponding to the push content according to the characteristic browsing data and the push adjustment rule.
Specifically, the characteristic style, characteristic browsing data of the characteristic category and the client activity are obtained, wherein the characteristic browsing data comprises browsing time and browsing duration, the browsing time indicates from which point in time to start browsing, and the browsing duration indicates the stay time length of an interface of the commodity; classifying the characteristic browsing data according to the browsing time; for example, the daily feature browsing data is taken as a class in units of days. Acquiring the browsing sum of the browsing duration of each type of characteristic browsing data; and calculating the correlation coefficient of the client liveness and the browsing sum based on a preset correlation calculation rule. The above-mentioned correlation calculation rule is a technical means known to those skilled in the art, and in this embodiment, the above-mentioned correlation calculation rule is a calculation method of a spearman correlation coefficient, that is, the above-mentioned correlation coefficient is a spearman correlation coefficient, and in other embodiments, other correlation calculation rules may be used, which is not limited herein. And adjusting the push content and the push duty ratio corresponding to the push content according to the correlation coefficient and the push adjustment rule. When the correlation coefficient is larger than zero and smaller than the correlation threshold, the client activity is positively correlated with the characteristic browsing data, but the client activity is not obviously improved, and the current push content is kept, namely the push duty ratio corresponding to the push content is not adjusted; when the correlation coefficient is larger than the correlation threshold, the client activity is positively correlated with the characteristic browsing data, the client activity is obviously improved, and the push duty ratio corresponding to the push content is increased based on the duty ratio adjustment table; when the correlation coefficient is smaller than zero, the push content corresponding to the increased feature style and feature category, which indicates that the client liveness is inversely correlated with the feature browsing data, reduces the client liveness, and based on the duty ratio adjustment table, reduces the push duty ratio corresponding to the push content. The above-mentioned calculation method of the client activity is a technology known to those skilled in the art, and will not be described herein. The duty cycle adjustment table includes a correlation coefficient and a corresponding adjustment duty cycle.
In one example, the correlation coefficient is a spearman coefficient, the correlation threshold is 0.5, when the correlation coefficient is greater than 0 and less than 0.5, the client activity is positively correlated with the characteristic browsing data, but there is no obvious positive effect on improving the client activity, and the current push content is maintained, i.e. the push duty ratio corresponding to the push content is not adjusted. When the correlation coefficient is greater than 0.5, the client activity is positively correlated with the feature browsing data, the push content corresponding to the feature style and the feature category plays a certain positive role in the client activity, the push duty ratio corresponding to the push content is increased based on the duty ratio adjustment table, for example, when the correlation coefficient is 0.7, the corresponding adjustment duty ratio is +5%, namely, the push duty ratio of the commodity corresponding to the feature category and the feature style is increased by five percent. When the correlation coefficient is smaller than 0, the push content corresponding to the characteristic style and the characteristic category, which indicates that the client activity is negatively correlated with the characteristic browsing data, has a certain negative influence on the client activity, and based on the duty ratio adjustment table, the push duty ratio corresponding to the push content is reduced, for example, the correlation coefficient is-0.3, and the corresponding adjustment duty ratio is-10%, namely, the duty ratio of commodity push corresponding to the characteristic category and the characteristic style is reduced by ten percent. When the reduced duty ratio is larger than the original push duty ratio, the push of the characteristic style and the characteristic category is deleted, for example, the duty ratio corresponding to the characteristic style and the characteristic category is ten percent, the adjustment duty ratio is-20 percent, namely, the push duty ratio of twenty percent is reduced by more than ten percent, so that the push content corresponding to the characteristic style and the characteristic category is deleted.
