Patent Application
20200111145
This application relates to the field of computer and material technologies, and in particular, to a product information integration and orchestration method and a cloud service apparatus.
After network cloud ecology is opened, primary integrators face massive problems of integration, customization, and delivery of cross-vendor information.
A currently adopted solution is mainly: Cross-vendor information is manually integrated, user-generated content (User Generated Content, UGC) is mainly customized manually, and the content is shared and transferred manually. For example, a user obtains an information packet of a vendor A, an information packet of a vendor B, and UGC content of various channels, and the user obtains an information segment of the vendor A, an information segment of the vendor B, and a UGC content segment through manual integration.
However, in the foregoing solution, there is no unified support management platform, and it is very difficult to ensure quality and efficiency of cross-vendor information integration and UGC content customization. As a result, it is unable to adapt to transformation of on-demand customization of product information.
This application provides a product material integration and orchestration method and a cloud service apparatus, to provide an automated orchestration service, improve orchestration efficiency, and satisfy a requirement for on-demand customization of product material.
In view of this, a first aspect of this application provides a product material integration and orchestration method, may include:
First, a cloud service apparatus for orchestrating information on demand is developed. A product model and an information model corresponding to a product description object class in the product model are built, product information components in a one-to-one correspondence to product description objects are defined, so that product material is conveniently automatically or manually customized and assembled according to an assembling rule of a product. In addition, based on this, persons of various writing abilities in a product life cycle who are authorized with and opened to an orchestration capacity of a product information component and a product information deliverable can define a product information model, a semantic product information component, and metadata (Metadata), so that the persons can readily access the Internet to perform low-entry-barrier DIY on-demand orchestration of product information. For example, the cloud service apparatus obtains target content, where the target content includes at least one of the following content: user-generated semantic content, existing semantic content, and semantic content in an orchestration system; and the cloud service apparatus orchestrates the target content based on the product model and the information model, to obtain a product information deliverable. It can be learned that, the cloud service apparatus can provide an automated orchestration service, to improve orchestration efficiency and satisfy a requirement for on-demand customization of product material.
In some possible implementations, the method may further include: after the product model and the information model corresponding to the product model are built, automatically or manually customizing or assembling, by a user using the orchestration system, required product material according to a logic rule used for assembling the product description object into a product, to obtain the customized or assembled product material by using the cloud service apparatus.
In some other possible implementations, if the target content includes the user-generated semantic content, the obtaining target content may be: determining, by the user using the orchestration system, based on a difference between a to-be-customized product whose information needs to be orchestrated by the user and an existing product description object tree and a product description object model in the orchestration system, whether the product description object class needs to be newly added. If the product description object class needs to be newly added, the user needs to customize an information component content model corresponding to the product description object class. Correspondingly, the cloud service apparatus obtains the product description object class newly added by the user; determines a first information component content model corresponding to the product description object class; determines a first UGC component based on the first information component content model; may select semantic archiving; and obtains, based on the first UGC component, semantic content newly written by the user or semantic content rewritten by the user.
In some other possible implementations, if the target content includes the user-generated semantic content, the obtaining target content may further be: determining, by the user using the orchestration system, based on a difference between a to-be-customized product whose information needs to be orchestrated by the user and an existing product description object tree and a product description object model in the orchestration system, whether a product description object needs to be newly added. If the product description object needs to be newly added, the user may newly write semantic content in an information component content model in the product description object. Correspondingly, if the product description object needs to be newly added, a second information component content model corresponding to the product description object is determined, a second UGC component is determined based on the second information component content model, and semantic content newly written by the user or semantic content rewritten by the user is obtained based on the second UGC component.
In some other possible implementations, if the target content includes the existing semantic content, the obtaining target content may further be: determining, by the user using the orchestration system, whether there is existing non-semantic content such as third-party information content or already existing content that needs to be introduced to the orchestration system through conversion, and if determining that there is existing non-semantic content that needs to be introduced to the orchestration system through conversion, completing conversion of the existing non-semantic content by using the cloud service apparatus. That is, the cloud service apparatus obtains the existing non-semantic content, and converts the existing non-semantic content into the existing semantic content.
In some other possible implementations, the converting the existing non-semantic content into the existing semantic content may be: defining, by the user using the orchestration system, based on information of an existing product, a product description object tree of the existing product, and abstracting a description object class of the product based on this, and complementing metadata related to newly-added existing content; customizing, by the user, an information component model corresponding to the newly-added description object class of the existing product; and converting an information deliverable template of the existing product into an information deliverable template that is based on the product description object class by using the cloud service apparatus; and generating a standard information component list of the existing product based on the product description object tree, a product information component model, and the information deliverable template. Correspondingly, the cloud service apparatus determines the product description object tree of the existing non-semantic content; determines the product information component model that corresponds to the newly-added product description object class of the existing non-semantic content and that is customized by the user; converts an information deliverable template of the existing non-semantic content into the information deliverable template that is based on the product description object class; and converts the existing non-semantic content into the existing semantic content based on the product description object tree, the product information component model, and the information deliverable template.
In some other possible implementations, if the target content includes the semantic content in the orchestration system, the obtaining target content may further be: determining, by the user using the orchestration system, whether the existing semantic content in the orchestration system needs to be filtered and orchestrated, and if the user needs to filter and orchestrate the existing semantic content in the orchestration system, filtering and orchestrating the existing semantic content in the orchestration system by using the cloud service apparatus. That is, the cloud service apparatus may obtain the product description object tree, and filter and orchestrate the product description object tree, to obtain the semantic content; or the cloud service apparatus may obtain an initial product information deliverable in the orchestration system, and filter and orchestrate the initial product information deliverable, to obtain the semantic content.
A second aspect of this application provides a cloud service apparatus, and the cloud service apparatus is configured to implement functions of the method provided in the first aspect or any optional implementation of the first aspect. The cloud service apparatus is implemented by using software, the software of the cloud service apparatus includes modules corresponding to the foregoing functions, and the modules are configured to implement the corresponding functions.

This application provides a product material integration and orchestration method, and the following describes an application scenario of product material integration and orchestration of this application. Referring to
The enterprise information development cloud platform is an information development cloud environment used by professional information developer in an enterprise, including a professional product information design, development, translation, and publishing platform, a product model (a product description object library), a content model (an information component content model and an information deliverable model), and a semantic product information component library.
The enterprise information delivery cloud platform is a platform by using which product information deliverables corresponding to full products are usually delivered to a user. The cloud service apparatus provided in this application is deployed on the information delivery cloud platform, and users who may access the Internet may access an information orchestration cloud service by using a browser based on permission, to orchestrate information on demand.
The cloud data center of the site A and the cloud data center of the site X may represent a cloud data center of each site, and a corresponding cloud service is deployed in the cloud data center. Usually, a cloud data center of a site is a relatively closed environment. In this case, a person at the site may directly orchestrate semantic content in a product information deliverable library in an information center cloud service by using the information orchestration cloud service, to customize and orchestrate related product information content for a secondary developer or a renter at the site.
The following describes the cloud service apparatus provided in this application, and the cloud service apparatus may be divided into six layers, namely, a user layer, a user interface layer, a business service layer, a data management service layer, a data invocation service layer, and a data layer.

The following describes a product material integration and orchestration method in this application by using an embodiment. Referring to
101. Obtain target content, where the target content includes at least one of the following content: user-generated semantic content, existing semantic content, and semantic content in an orchestration system.
In this embodiment, a cloud service apparatus builds a product model and an information model corresponding to a product description object class in the product model, and the cloud service apparatus defines a correspondence between product description objects and product information components.
The target content obtained by the cloud service apparatus includes at least one of the following content: the user-generated semantic content, the existing semantic content, and the semantic content in the orchestration system.
For example, when a user enters into an orchestration service interface of the cloud service apparatus, the user determines whether the user has content that needs to be newly written or content that needs to be rewritten. Herein, the content that needs to be newly written or content that needs to be rewritten is relative to existing semantic content in the orchestration system. If the user uses the semantic content already provided by a vendor in the orchestration system to perform only a logic-level change, it indicates that the user does not have content that needs to be newly written or content that needs to be rewritten. If the user determines that the user has content that needs to be newly written or content that needs to be rewritten, the user needs to generate semantic content. After the cloud service apparatus determines that the user has a demand for generating the semantic content, the cloud service apparatus may support the user in completing an operation of generating the semantic content, that is, the target content obtained by the cloud service apparatus includes the user-generated semantic content.
For another example, when the user enters the orchestration service interface of the cloud service apparatus, the user determines whether there is existing non-semantic content converted into the semantic content, the non-semantic content may be third-party information content, already existing content, or the like. If the user determines that there is existing non-semantic content that needs to be converted into existing semantic content, after the cloud service apparatus determines that the user has a demand for converting the existing non-semantic content into the existing semantic content, the cloud service apparatus may support the user in converting the existing non-semantic content into the existing semantic content, that is, the target content obtained by the cloud service apparatus includes the existing semantic content.
For another example, when the user enters the orchestration service interface of the cloud service apparatus, the user determines whether the existing semantic content in the orchestration system needs to be filtered and orchestrated. If the user determines that the existing semantic content in the orchestration system needs to be filtered and orchestrated, after the cloud service apparatus determines that the user has a demand for filtering and orchestrating the existing semantic content in the orchestration system, the cloud service apparatus may support the user in filtering and orchestrating the existing semantic content in the orchestration system, that is, the target content obtained by the cloud service apparatus includes the semantic content in the orchestration system.
In some possible implementations, the method may further include: assembling or customizing product material according to a logic rule used for assembling the product description object into a product.
In this embodiment, after the product model and the information model corresponding to the product model are built, the user using the orchestration system automatically or manually customizes or assembles required product material according to the logic rule used for assembling the product description object into a product, to obtain the customized or assembled product material by using the cloud service apparatus.
In some possible implementations, if the target content includes the user-generated semantic content, the obtaining target content includes: obtaining a product description object class newly added by a user; determining a first information component content model corresponding to the product description object class; determining a first user-generated content UGC component based on the first information component content model; and obtaining the user-generated semantic content based on the first UGC component, where the user-generated semantic content includes semantic content newly written by the user or semantic content rewritten by the user.
In this embodiment, the user using the orchestration system determines, based on a difference between a to-be-customized product whose information needs to be orchestrated by the user and an existing product description object tree and a product description object model in the orchestration system, whether a product description object class needs to be newly added. If the product description object class needs to be newly added, the user needs to customize an information component content model corresponding to the product description object class. Correspondingly, the cloud service apparatus obtains the product description object class newly added by the user; determines the first information component content model corresponding to the product description object class; determines the first UGC component based on the first information component content model; may select semantic archiving; and obtains, based on the first UGC component, semantic content newly written by the user or semantic content rewritten by the user.
In some possible implementations, if the target content includes the user-generated semantic content, the obtaining target content includes: obtaining a product description object newly added by a user; determining a second information component content model corresponding to the product description object; determining a second UGC component based on the second information component content model; and obtaining the user-generated semantic content based on the second UGC component, where the user-generated semantic content includes semantic content newly written by the user or semantic content rewritten by the user.
In this embodiment, the user using the orchestration system determines, based on a difference between a to-be-customized product whose information needs to be orchestrated by the user and an existing product description object tree and a product description object model in the orchestration system, whether a product description object needs to be newly added. If the product description object needs to be newly added, the user may newly write semantic content in an information component content model in the product description object. Correspondingly, if the product description object needs to be newly added, the second information component content model corresponding to the product description object is determined, the second UGC component is determined based on the second information component content model, and the semantic content newly written by the user or the semantic content rewritten by the user is obtained based on the second UGC component.
In some possible implementations, if the target content includes the existing semantic content, the obtaining target content includes: obtaining the existing non-semantic content; and converting the existing non-semantic content into the existing semantic content.
In this embodiment, the user using the orchestration system determines whether there is existing non-semantic content such as third-party information content or already existing content that needs to be introduced to the orchestration system through conversion, and if determining that there is existing non-semantic content that needs to be introduced to the orchestration system through conversion, the user completes conversion of the existing non-semantic content by using the cloud service apparatus. That is, the cloud service apparatus obtains the existing non-semantic content, and converts the existing non-semantic content into the existing semantic content.
In some possible implementations, the converting the existing non-semantic content into the existing semantic content includes: determining a product description object tree of the existing non-semantic content; determining a product information component model that corresponds to the newly-added product description object class of the existing non-semantic content and that is customized by the user; converting an information deliverable template of the existing non-semantic content into an information deliverable template that is based on the product description object class; and converting the existing non-semantic content into the existing semantic content based on the product description object tree, the product information component model, and the information deliverable template.
In this embodiment, the user using the orchestration system defines, based on information of an existing product, a product description object tree of the existing product, and abstracts a description object class of the product based on this, and complements metadata related to newly-added existing content; the user customizes an information component model corresponding to the newly-added description object class of the existing product; and converts an information deliverable template of the existing product into an information deliverable template that is based on the product description object class by using the cloud service apparatus; and generates a standard information component list of the existing product based on the product description object tree, the product information component model, and the information deliverable template. Correspondingly, the cloud service apparatus determines the product description object tree of the existing non-semantic content; determines the product information component model that corresponds to the newly-added product description object class of the existing non-semantic content and that is customized by the user; converts an information deliverable template of the existing non-semantic content into the information deliverable template that is based on the product description object class; and converts the existing non-semantic content into the existing semantic content based on the product description object tree, the product information component model, and the information deliverable template.
In some possible implementations, if the target content includes the semantic content in the orchestration system, the obtaining target content includes: obtaining the product description object tree; and filtering and orchestrating the product description object tree, to obtain the semantic content; or obtaining an initial product information deliverable in the orchestration system; and filtering and orchestrating the initial product information deliverable, to obtain the semantic content.
In this embodiment, the user filters and orchestrates the product description object tree, for example, adds an object, deletes an object, modifies an object, or changes a logic layer of an object tree, to automatically filter customized product information corresponding to the product description object tree. Alternatively, the user filters, by directly defining a filtering condition, a product information deliverable that is provided by the vendor in the orchestration system, selects content required by the user, and then implements orchestration.
102. Orchestrate the target content based on a product model and an information model, to obtain a product information deliverable.
In this embodiment, the cloud service apparatus may perform mixed orchestration on the target content based on the product model and the information model, to obtain a product information deliverable.
For example, the cloud service apparatus may perform, based on the product model and the information model, on-demand mixed orchestration on the semantic content provided by the vendor, the user-generated semantic content, and the existing semantic content obtained after conversion in the orchestration system, and publish content obtained after the on-demand mixed orchestration as a user-customized product information deliverable.
In this embodiment, an automated orchestration service is provided based on the product model and the information model, efficiency and quality are improved, entry barriers and difficulty of information orchestration are reduced, and the automated orchestration service is applicable to unprofessional information developers of various skills.
In addition, a user development capacity and an automated orchestration and assembling capacity based on a model and a template are opened based on permission. This is quick and convenient. An automatic batch conversion function is provided, so that it is convenient to convert, in a unified manner, massive third-party existing content into semantic content that can be managed and orchestrated by a system.
Finally, requirements of products for ready, on-demand, online, convenient design and development of product material, open ecology, and the like are satisfied.
