Description

A method and device for determining a service plan

technical field

The present invention relates to the field of communication technologies, and in particular, to a method and apparatus for determining a service scheme.

Background technique

With the development of cloud computing, SaaS (Software as a Service, software as a service) model is becoming more and more popular as a novel service delivery model. Compared with the traditional software development model, software developers do not need to develop the required applications according to the individualized and diverse needs of each user. On the contrary, the SaaS model delivers applications in a multi-tenant model. Multi-tenancy means that the same application instance provides software services for thousands of users, which greatly reduces the cost of running the application and the corresponding management expenses. Each user is called a tenant. Through this multi-tenancy mechanism, a huge user scale can be supported more economically. Therefore, as users have more and more personalized and diverse needs, multi-tenant-oriented network applications are the main delivery mode of future applications.

At the same time, in order to adapt to complex application development, application components are also developing towards a modular and fine-grained direction. However, due to the wide range of client layers faced by complex network application services, the business requirements put forward by tenants are often diverse, some are very abstract and some are very specific, showing the characteristics of granularity. However, although traditional methods consider the multi-granularity of requirements, they do not propose corresponding countermeasures for the individual needs of each tenant.

To sum up, under the current SaaS model, there is an urgent need for a method that can quickly and accurately determine a corresponding service solution for a tenant according to their needs.

Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

FIG. 1 is a schematic flowchart corresponding to a method for determining a service scheme provided by an embodiment of the present invention, and the method includes:

Step 101: Obtain request information of a tenant; the request information at least includes a demand target of the tenant;

Step 102: Query the first service granularity space to obtain a first target service that matches the demand target; the services in the first service granularity space are obtained from services having common attributes in the second service granularity space;

Step 103, query the second service granularity space according to the first target service, and obtain a second target service corresponding to the first target service in the second service granularity space;

Step 104: Determine a service plan of the tenant according to the second target service.

The second service granularity space described in the embodiment of the present invention includes a large number of services, these services are all specific services, and each service has a corresponding software code. The services in the first service granularity space are obtained from services having common attributes in the second service granularity space, that is, there is a corresponding relationship between the first service granularity space and the services in the second service granularity space. Before implementing the determination of the tenant's service scheme according to the tenant's request message in the embodiment of the present invention, the first service granularity space needs to be constructed in advance according to the second service granularity space.

The construction process of the first service granularity space will be specifically described below.

2 is a schematic flowchart of determining a service in the first service granularity space in an embodiment of the present invention, and the specific steps are as follows:

Step 201, according to the semantic similarity between each service in the second service granularity space, cluster the services in the second service granularity space to obtain different service clusters;

Step 202, according to the input and output of each service in each service cluster, obtain the representative service of each service cluster; the input of the representative service is the common input of the service cluster, and the output of the representative service is the service cluster common output;

Step 203, taking the representative service as a service in the first service granularity space.

Specifically, different service clusters are pre-stored in the second service granularity space for different categories of services. In step 201, for the service that is not clustered in the second granularity space, calculate the semantic similarity between the service and other services, if the semantic similarity between the service and each service in a certain service cluster is greater than Threshold, the service is added to the service cluster. Otherwise, continue to judge the semantic similarity between the service and the services in the next service granular cluster until all the service clusters in the second service granularity space are judged. If the judgment is completed, the service does not belong to the second service granularity space If any of the service clusters are found, a new service cluster is re-created for the service, and the service is added to the newly created service cluster. Then, continue to judge the next service that is not clustered in the second service granularity space, and the clustering ends when all the services that are not clustered find the service cluster to which they belong. In other words, the services in the first service granularity space are divided into service clusters according to the similarity of the services in the second granularity space, and the representative services with common attributes in each service cluster are regarded as the services in the first service granularity space. .

The above process will be described below with reference to specific examples.

It is assumed that the original service clusters in the second service granularity space are service cluster 1, service cluster 2, service cluster 3, service cluster 4, and service cluster 5. The services that are not clustered are service a1, service a2, and service a3. Calculate the similarity between service a1 and service cluster 1, service cluster 2, service cluster 3, service cluster 4, and service cluster 5. If the semantic similarity between service a1 and any service in service cluster 1 is greater than the threshold, the service a1 is added to service cluster 1. Calculate the similarity between service a2 and service cluster 1, service cluster 2, service cluster 3, service cluster 4, and service cluster 5. If the semantic similarity between service a2 and any service particle in service cluster 2 is greater than the threshold, then Service a2 is added to service cluster 2. Calculate the similarity between service a3 and service cluster 1, service cluster 2, service cluster 3, service cluster 4, and service cluster 5. If the semantic similarity between service a3 and any service in service cluster 3 is greater than the threshold, the service a3 is added to service cluster 3.

Extract the common input and output concepts of all services in service cluster 1 to form a new service b1, extract the common input and output concepts of all services in service cluster 2 to form a new service b2, and extract the common input and output concepts of all services in service cluster 3. A new service b3 is formed, the common input and output concepts of all service granules in service cluster 4 are extracted to form a new service b4, and the common input and output concepts of all service granules in service cluster 5 are extracted to form a new service b5. Service b1, service b2, service b3, service b4, and service b5 are representative services of service cluster 1, service cluster 2, service cluster 3, service cluster 4, and service cluster 5, respectively. Service b1, service b2, service b3, service b4, and service b5 are used as services in the first service granularity space.

After the representative service is obtained through the above steps, the representative service with the associated relationship can also be combined to obtain the composite service, that is, the associated service is formed into a workflow. One way is the output concept of the previous service and the input of the latter service. Concept matching; another way is to match the output of the previous services with the input of the latter service, so as to organize the related services in a certain sequence, showing that one service calls another service to realize the message The transmission of the first service can generate functions that a single service does not have, and further improve the granularity space of the first service.

Specifically, service b1, service b2, service b3, service b4, and service b5 are combined according to the association relationship among service b1, service b2, service b3, service b4, and service b5 in the first service granularity space. If the output concept of the service b1 matches the input concept of the service b2 (the service b1 and the service b2 have an associated relationship), the service b1 and the service b2 are organized in sequence to obtain the combined service b1-b2. For example, service b2 (City2ZipCode) is a service for querying city zip codes. Its input is Cityname, and its output is zipCode. If there is a match between the output concept of service b1 and the input concept of service b2, it can be determined that service b2 and service b1 have The association relationship is to combine the service b2 and the service b1 to obtain the combined service b1-b2. Alternatively, the output concepts of service b3 and service b4 can be matched with the input concept of service b5, and a combined service consisting of service b3, service b4 and service b5 can be obtained. As shown in Figure 3, the output and Schematic diagram of the composite service where the input of the latter service is matched.

It should be noted that since a coarse-grained service has the same functions as multiple fine-grained services, when the aggregation degree between the fine-grained service and the coarse-grained service reaches a certain threshold, it indicates that the coarse-grained service has the same function. The service can be hierarchically decomposed into a combination of fine-grained services, which is manifested in that the semantic similarity between the input and output of the coarse-grained service and the input and output of the starting service and ending service of the combined service is greater than the first threshold, where the first A threshold can be set according to the actual situation. Therefore, in the embodiment of the present invention, the relationship between the representative service and the composite service can also be obtained according to the semantic similarity between the representative service and the composite service in the first granularity space: if the representative service in the first granularity space and the composite service are If the semantic similarity between them is greater than the first threshold, the representative service is regarded as a similar service of the combined service, so that the user can be provided with more selectable service solutions according to the user's needs.

As shown in Figure 4, it is a schematic diagram of the hierarchical relationship between the representative service and the composite service. Service c1, service c2 and service c3 constitute composite service c1-c2-c3, if the input of service c4 is similar to the input of start service c1 in the composite service, the output of service c4 is similar to the output of end service c3 in the composite service, Then the service c4 can be equivalent to the combined service c1-c2-c3.

In this embodiment of the present invention, after the request message is obtained in step 101, in step 102, the first service granularity space may be queried according to the demand target of the tenant contained in the request message, so as to obtain the first service granularity space matching the demand target. A target service.

On the one hand, because in the actual process, the tenant's demand target involves various fields, therefore, there may or may not exist services matching the demand target in the relatively limited first service granularity space. For the situation that there is a service matching the demand target in the first service granularity space, the embodiment of the present invention directly regards the service matching the demand target as the first target service; for the first service granularity space When there is no service matching the demand target, the embodiment of the present invention first parses the demand target, and automatically generates a service matching the analysis result according to the analysis result and the existing services in the first granularity space, Then, the service that matches the analysis result is used as the first target service, so that the first target service that meets the needs is automatically generated by analyzing the tenant's demand target, which not only meets the various needs of users, but also improves the tenants' needs. Determine the accuracy of the service plan.

On the other hand, the scope of tenants' demand objectives is also diverse, that is, the requirements are multi-granular. For example, some medium-sized enterprises propose to build a large-scale e-commerce application, while some small enterprises may require logistics management. application. In contrast, the granularity of requirements proposed by the former is coarser than that of the latter. In view of the above situation, in the embodiment of the present invention, the first target service that meets the needs of the tenant can be determined according to whether the request message of the tenant includes a customized service: if the request message does not include the customized service, the tenant may need to A coarser-grained service may also require a finer-grained service. Therefore, when the obtained service that matches the demand target is a representative service, and the representative service is a similar service of the combined service, the representative service and the corresponding The composite service is determined as the first target service to meet the tenant's needs, so that the tenant can choose according to their actual needs; if the request message contains a customized service, that is, the tenant has customized a finer-grained service based on the demand target. At this time, only the combined service that includes the customized service in the service matching the requirement target may be used as the first target service.

In this embodiment of the present invention, after the first target service is acquired according to step 102, in step 103, according to the first target service and the corresponding relationship between the service in the first service granularity space and the service in the second service granularity space, from the first target service The service corresponding to the first target service is obtained in the second service granularity space. If the request message of the tenant includes the QoS requirement of the tenant, a service corresponding to the first target service in the second service granularity space and satisfying the QoS requirement of the tenant is acquired as the second target service. If the request message of the tenant does not contain the QoS requirement of the tenant, the services corresponding to the first target service in the second service granularity space are sorted according to the QoS, and the service whose QoS meets the second threshold is regarded as the first target service. Two target services; the second threshold can be set according to the actual situation.

In step 104, according to the second target service, a specific service corresponding to the second target service is determined, so as to determine the service plan of the tenant. Specifically, the service customized by the tenant may be used as the service solution of the tenant by receiving the customization instruction of the tenant for the second target service.

Specifically, in the stage of determining the service plan, before receiving the tenant's customization instruction for the second target service, the following elimination processing is performed: For example, assuming that the specific services corresponding to the second target service include service C and service D, the price of service C is is 65, the response time is 10s, the price of service D is 50, and the response time is 6s, then in the process of determining the second target service, service C can be automatically eliminated. For the services that satisfy the same function, some are the representative service S, and some are the composite service s1-s2 which is equivalent to the representative service S. Compare the QoS attributes of the composite service s1-s2 and the representative service S. If the QoS attribute of the composite service s1-s2 is superior For the QoS attribute of the representative service S, the representative service S is eliminated. After the above-mentioned culling process, the uneliminated services are returned to the tenant for selection by the tenant, and obviously bad services are filtered out in this way, which can further facilitate the user to customize according to the returned service.

Preferably, in this embodiment of the present invention, the service further includes inheritance and version management. According to the unique properties of the service, the inheritance operation is mainly manifested in the following aspects: the inheritance of the user interface, the inheritance of the descriptive definition, the inheritance of the process and the inheritance of the data schema. Among them, the inheritance of the user interface includes changing the content of the interface, changing the structure of the interface, changing the content of the interface including adding modules, adjusting the font size, changing the style of the table, etc. Changing the structure of the interface includes adjusting the layout of the module, changing the display effect, changing the Location of pictures or menus, etc. Inheritance of process includes adding process and deleting process, adding process includes sequential adding, parallel adding and selective adding, and deleting process includes sequential deleting, parallel deleting and selective deleting. The inheritance of descriptive definitions includes adding parameter types, adding input and output parameters, deleting parameter types, modifying parameter types, and deleting input and output parameters. The inheritance of data schema includes adding data fields, deleting data fields and modifying data fields. Due to changes in market demand, service providers will regularly update applications, and tenants will also customize the required attributes. These updates will break the tenant's original service version, so that tenants' respective service instances have different versions, and tenants can choose to migrate to The new version can also be delayed to stay on the old version in order to maintain the availability of the application. The embodiment of the present invention realizes the version management of the service by recording the difference between the old and new versions.

The present invention will be further described below in conjunction with specific examples.

Assuming that the model of the first service granularity space is shown in Figure 5, the services in the first service granularity space include: service P for vacation, service Q to book air tickets, service S to apply for visa, service T to book hotels & sightseeing, and service R to book train tickets , Service X to book hotels, Service Y to travel.

If the tenant's needs are relatively simple, such as wanting a sightseeing service, then service Y can meet the demand. At this time, service Y is the first target service. According to the first target service, query the second service granularity space, and the corresponding first target service can be obtained. Second target service, the specific service can be selected from the specific service set corresponding to the second target service according to the QoS requirement.

If a tenant wants a vacation plan service, and its demand target is: vacation, and customizes service Q, service S, and service X, the services that can be obtained according to the tenant's demand target and matching the demand target include: (1 ) service P; (2) combined service Q-S-T; (3) combined service R-S-T; (4) combined service Q-S-X-Y; (5) combined service R-S-X-Y. Further according to the customized service of the tenant, it can be obtained that the first target service is a combined service Q-S-X-Y including service Q, service S, and service T. According to the obtained first target service, the second target service corresponding to each service in the first target service can be obtained, and then a specific service is selected according to the QoS requirement, and a service plan of the tenant is determined.

The tenant can also choose the method of customizing and recommending it by the system, that is, the tenant proposes the need for service Q, and selects a specific service from the specific services corresponding to service Q, and then the system can recommend the specific service corresponding to service S for the tenant. After selecting a specific service corresponding to service S, the system recommends specific services corresponding to service E or service F for it. In this way, according to the combined services in the first service granularity space and so on, the service that meets the needs of the tenant is finally obtained. Program.

In this embodiment of the present invention, by acquiring the tenant's request information, the first service granularity space is queried according to the tenant request message, and the first target service matching the demand target contained in the request message is acquired; wherein, in the first service granularity space The service is obtained from a service with a common attribute in the second service granularity space; according to the first target service, query the second service granularity space, and obtain the second service granularity space corresponding to the first target service the second target service; the tenant's service scheme is determined according to the second target service; the embodiment of the present invention constructs the first service granularity space according to the services with common attributes in the second service granularity space, and the first service granularity As the interface for tenants' access, the space first queries the first service granularity space and then the second service granularity space according to the user's request message, which simplifies the implementation details of specific services and improves the efficiency and accuracy of determining service plans.
