Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
The current service platform can provide services for screening suppliers for demanders, and generally sets screening conditions according to classification results of the suppliers, so that the demanders can select the screening conditions and match suitable suppliers according to self requirements. The service platforms such as job hunting platforms, housekeeping platforms, bid and bid platforms and the like are appeared, so that the matching efficiency of the demand side and the supply side is greatly improved.
However, the condition screening function of the service platform is not intelligent, and only the supplier is matched according to the screening condition selected by the demander, if the condition set by the demander is excessive, the condition that the supplier cannot be matched occurs, and the demander needs to reset the screening condition to match the supplier again, based on which, the embodiment of the invention firstly provides a supply and demand matching method, as shown in fig. 1, the supply and demand matching method comprises:
step S101, acquiring a plurality of conditions for screening suppliers corresponding to a demand side;
in this step, the demander refers to the user or the enterprise who is publishing the demand, and the supplier refers to the user or the enterprise who provides the service, for example, in the job hunting platform, the job hunter can be regarded as the demander, and the job hunter browses the enterprise which enters the job hunting platform and finds the enterprise which meets the desire of the job hunter to further know the salary treatment.
The plurality of conditions are set by the demand side for screening suppliers, and because the number of suppliers in the platform is possibly huge, in order to enable the demand side to screen out suitable suppliers, the service platform generally provides the demand side with a plurality of conditions for the demand side to select, so that the supply side can be screened out quickly.
Step S102, if the suppliers meeting the conditions are not found, determining weights corresponding to the conditions;
in the matching process of screening suppliers by using condition hierarchy, the step from the condition with the lowest importance degree to the beginning of relaxing search is particularly critical, because in practical application, a part of conditions set by a demand side are not hard requirements, if the condition is adopted and the rule is limited to be dead, all hard conditions that the supplier meets the demand side may exist, but the condition of no match occurs when the condition is deviated from the non-hard conditions, so in order to avoid the condition, the weights corresponding to the conditions are required to be determined.
In the embodiment of the present invention, for the case that the suppliers meeting the plurality of conditions are not found, the condition range set by the demander is too small, which results in the case that the suppliers meeting the conditions are not matched, so in this step, the embodiment of the present invention determines the important ranks of the plurality of conditions by determining the weight corresponding to each condition, which represents the importance degree of the condition, and further can widen the conditions from the condition with small weight, and gradually screen out the suppliers.
Step S103, determining a first target condition with weight meeting the setting requirement from the plurality of conditions;
in practical applications, the screening rule is generally set to be written to death, so that the situation that the supplier cannot be matched easily occurs, and in fact, the condition is relaxed to a certain extent due to non-rigid stipulations existing in the screening condition provided by the demand side, so that the embodiment of the invention determines the first target condition with the weight meeting the setting requirement from a plurality of conditions to perform subsequent relaxed condition processing.
The setting requirement may be determined according to an actual situation, for example, N conditions after ranking are selected as the first target condition according to the weight, preferably, the condition with the smallest weight is selected as the first target condition, and a situation that the matched supplier cannot meet the demand of the demander can be avoided.
Step S104, relaxing the first target condition into a second target condition;
step S105, determining the suppliers meeting the second target condition.
The embodiment of the invention realizes the purpose of searching for the supplier meeting the second target condition again by relaxing the first target condition into the second target condition, and particularly, the gradient of the phase difference between the second target condition and the first target condition can be determined according to the actual situation.
For example: in the home service platform, there are many periods of short supply (the employer increases in spring festival and the home staff decreases), and after the platform of the employer selects the screening conditions, the platform of the employer selects non-hard screening conditions in addition to the hard conditions set by the employer (such as cooking, nursing babies and the like), and when the home staff meeting the conditions of the employer cannot be matched, the non-hard screening conditions (such as commission, working years and the like) are correspondingly relaxed.
According to the method and the device, after the conditions which are corresponding to the demander and used for screening the suppliers are obtained, if the suppliers meeting the conditions are not found, the weights corresponding to the conditions are determined, then the first target conditions with the weights meeting the set requirements are determined from the conditions, the first target conditions are relaxed to be the second target conditions, the suppliers meeting the second target conditions are screened, the search range is automatically expanded, the suppliers meeting the conditions of the demander can be found for the demander without resetting the screening conditions, and the purpose of intelligent matching is achieved.
In practical applications, when the demander does not match the supplier meeting the multiple conditions set by the demander, that is, the supplier does not completely meet the multiple conditions, the embodiment of the present invention re-matches the supplier by using the condition with the lowest importance degree to ensure that the workload of repeated retrieval of the conditions set by the demander is reduced as much as possible, and simultaneously, the embodiment of the present invention can also meet the multiple conditions provided by the demander, but when too many suppliers are searched after the screening condition is relaxed, further screening is required, based on which, in another embodiment provided by the present invention, as shown in fig. 2, the supply and demand matching method further includes:
step S201, if at least two suppliers meeting the second target condition are found, determining a fourth target condition with the minimum weight from the rest conditions;
wherein the remaining condition refers to a condition other than the first target condition among the plurality of conditions.
Step S202, finding out the supplier meeting the fourth target condition from at least two suppliers meeting the second target condition.
In the embodiment of the present invention, when at least two suppliers meeting the second target condition are found, at least two suppliers are further screened by determining a fourth target condition with the minimum weight from the remaining conditions.
Further, if at least two suppliers are still matched by the fourth target condition, the condition with the smallest weight is selected again from the remaining conditions for screening with reference to the above embodiment until all the conditions are used. The embodiment of the invention can maximally fit a plurality of conditions set by a demand party by carrying out hierarchical screening on a plurality of suppliers, screen a proper supplier for the demand party, and ensure that the matched suppliers after the search range is expanded can be further screened out to meet the conditions while the condition screening is relaxed.
In an actual application scenario, the demander may set A, B, C three conditions, and if the server platform does not match the supplier meeting A, B, C three conditions at the same time, the server platform may preferentially select the condition C with the lowest importance degree among the three conditions to perform relaxed matching so as to search the supplier in a wider range.
In addition, in another embodiment of the present invention, a specific implementation manner is further provided for a case that at least two suppliers meeting the second target condition do not meet the fourth target condition, as shown in fig. 3, where the method includes:
step S301, if at least two suppliers meeting the second target condition do not meet the fourth target condition, relaxing the fourth target condition into a fifth target condition;
step S302, finding a supplier meeting the fifth target condition from at least two suppliers meeting the second target condition.
In an actual application scenario, A, B, C three conditions may be set by a demand party, if a server platform does not match a supplier meeting A, B, C three conditions at the same time, a condition C with the lowest importance degree of the three conditions is preferentially selected for relaxation matching, so as to search the supplier within a larger range, at this time, if at least two suppliers meeting the condition C are matched, a condition B (selected between a and B) with the lowest importance degree can be used, if none of the suppliers meeting the relaxed condition C meets the condition B, the condition B can be relaxed and matched, and similarly, when none of the suppliers meeting the relaxed condition B meets the condition a, the condition a can be relaxed and matched, so as to realize hierarchical screening of the suppliers.
Referring to the above embodiment for performing relaxation matching on the conditions, in the embodiment of the present invention, when at least two suppliers meeting the second target condition do not meet the fourth target condition, the fourth target condition is also relaxed to be the fifth target condition, so as to ensure that suppliers more meeting the conditions set by the demander can be continuously screened from the at least two suppliers.
In the matching process of screening suppliers by using condition hierarchy, the step from the condition with the lowest importance degree to the beginning of relaxing search is particularly critical, because in practical application, some conditions in the conditions set by the demander are not hard requirements, if the condition that the rule is limited to death is adopted, all hard conditions that the suppliers meet the demander may exist, but the condition that the suppliers do not match is present when the conditions deviate from the non-hard conditions in a millicentimeter, so in order to avoid the above condition, the weight (the weight is used for representing the importance degree of the condition) corresponding to each of the multiple conditions needs to be determined, based on this, the embodiment of the present invention provides a specific determination method of the weight, as shown in fig. 4, the determining the weight corresponding to each of the multiple conditions includes:
step S401, determining target group weight distribution information from a plurality of preset groups of weight distribution information;
in the embodiment of the present invention, multiple sets of weight distribution information are preset, where each set of weight distribution relationship includes multiple conditions and their respective corresponding weights, and multiple sets of weight distribution relationships may have overlapping conditions, for example: the weight assignment relationship a has a condition a, and the weight assignment relationship B also has a condition a.
However, the weights of the condition a in different pieces of weight distribution information are also different, specifically, the multiple pieces of weight distribution information respectively correspond to different application scenarios, and the application scenario information may be a matching rule formulated only by the service platform, or may be information representing a supply-demand relationship between a current demand side and a supplier, for example: the application scenario may include: the number of suppliers is greater than the number of demanders, the number of suppliers is equal to the number of demanders, and the number of suppliers is less than the number of demanders.
Based on this, in step S401, the determining target group weight distribution information from the preset multiple groups of weight distribution information, as shown in fig. 5, includes:
step S501, obtaining an application scene when the demand side matches the supplier side;
in the embodiment of the present invention, the manner of obtaining the application scenario may be directly obtained from the service platform, and preferably, the service platform may determine the application scenario according to a supply-demand relationship between a current demand party and a supplier, for example: when the number of suppliers is greater than that of demanders, more rigorous screening can be performed for demanders, and when the number of suppliers is less than that of demanders, the search conditions can only be relaxed for demanders to match to suppliers. The weight setting of different weight distribution information corresponding to the same condition will directly affect the matching result.
Scene one:
in practical applications, the demander may be an employer, the supplier may be a housekeeper, the demander conditions are "commission", "cook-up" and "region", the "cook-up" is a rigid requirement for the employer, and during spring festival, when the number of employers increases and the number of housekeepers decreases, the "commission" condition is relaxed, the housekeepers are matched as much as possible, and then the "region" condition is used to further search for qualified housekeepers.
Scene two:
the conditions of the demand side are "commission", "year of employment", "cooking" and "region", and "cooking" is a rigid demand for the employer, and the priority of the relaxation of the "commission" condition can be lower than the non-rigid demands of the "region" and the "year of employment" in the period of low employer number and high housekeeping person number.
Step S502, searching target weight distribution information matched with the application scene from the multiple groups of weight distribution information.
In this step, each set of weight distribution information corresponds to one application scenario, and the current application scenario is obtained from the service platform, so that the target weight distribution information matched with the application scenario can be found from the sets of weight distribution information.
In the embodiment of the invention, the weight setting of each condition in the weight distribution information corresponding to the application scene can be determined according to the actual situation, and the aim is to change the matching rule in real time according to the application scene, so that the intelligent matching process is realized.
Step S402, determining weights corresponding to the plurality of conditions based on the target weight distribution information.
In this step, the target weight assignment information includes weights corresponding to the plurality of conditions, and the embodiments of the present invention can adjust the weights of the plurality of conditions according to changes in application scenarios, and even if the same setting conditions are used, the weight assignments may be different in different application scenarios, so that compared with the conventional case of matching supply and demand by only using a write-down condition, an intelligent matching process is implemented.
