## Title
Semantic analysis driven service creation within a multi-level business process

## Abstract

A multi-level business process interface associated with an incomplete Web service can be identified. The interface can be created within a user interface (UI) modeling tooling. The Web service can be associated with a business process. An interface specific metadata associated with the process interface can be determined. Service definitions for one or more existing Web service matching a portion of the interface specific metadata can be searched for semantically based on search depth parameters set by a user. A search result responsive to the searching can be returned. The search result can identify one or more existing Web services from a service registry.

## Background
BACKGROUND
The present invention relates to the field of Web service development and, more particularly, to semantic analysis driven service creation in a multi-level business process.
Web services are frequently associated with business processes which model necessary stages for achieving a business objective. The Web services can be an implementation of a business process, a portion of a business process, or multiple business processes. Existing Web services and are often used to create new services rapidly by leveraging software development practices such as software reuse. For example, two or more Web services can be combined into a single service which can provide greater functionality than the services individually.
Traditional Web service creation often requires manual searches for service definitions by using specific keywords to search for the definitions. The definitions can be retrieved from registries such as internal registry, an external registry, or cloud registry. Once retrieved service objects must be manually mapped to the service being created. This traditional process can be a time consuming endeavor and can also require industry specific knowledge to identify appropriate search keywords. That is, existing Web services can go unused due to difficulty in determining the service existence. For example, a service can be tagged with jargon keywords which can render the service difficult to find. Further, traditional approaches fail to permit searching low-level details (e.g., operations) of Web services and/or business processes.
BRIEF SUMMARY
One aspect of the present invention can include a system, an apparatus, a computer program product, and a method for semantic analysis driven Web service creation. A multi-level business process within a computing environment can be identified. The interface can be created within a user interface (UI) modeling tooling. The Web service can be associated with a business process. An interface specific metadata associated with the process interface can be determined. Service definitions for one or more existing Web service matching a portion of the interface specific metadata can be searched for semantically. A search result responsive to the searching can be returned. The search result can identify one or more existing Web services from a service registry.
Another aspect of the present invention can include an apparatus, a computer program product, a method, and a system semantic analysis driven Web service creation. A tooling engine can be able to automatically generate Web service artifacts associated with an interface of an incomplete Web service. The interface can be associated with interface specific metadata. The incomplete Web service can be associated with a business process. A data store can be configured to persist a search result associated with a semantic search. The search result can identify at least one existing Web service matching a portion of the interface specific metadata.

FIG. 1 is a schematic diagram illustrating a flow 100 for semantic analysis driven service creation in a multi-level business process in accordance with an embodiment of the inventive arrangements disclosed herein. Flow 100 can be performed in the context of method 200 and system 300. Flow 100 can include stages 101, 110, 140, 170 and can include optional stages not shown herein. In flow 100, a business process 102 can be selected for implementation. The business process 102 can be a collection of related structured activities (e.g., tasks) which can produce a specific service and/or product. For example, a business process can be a series of workflows for a Web service for retrieving Web site user account details. The interface definition 109 can be defined within a modeling tool (e.g., tooling screen 103) and can be utilized to create an automatically generated service 170. That is, the disclosure can facilitate rapid and easy top-down Web service creation.
In define implementation 101, a business process 102 can be inputted into a tooling screen 103. Utilizing tooling screen 103, a process implementation 108 can be created. For example, the process implementation 108 can be a new Web service being created by a user. The process implementation 108 can include an interface definition 109. The interface definition 109 can be generated from user input received within tooling screen 103. For example, a developer can employ business process flowcharts to manually define an interface definition 109 for business process 102. The interface definition 109 can be an entity specifying the location of the implementation 108 (e.g., URL) and the operations the implementation exposes. In one instance, the interface definition 109 can be a Web Services Description Language (WSDL) document. In the instance, the definition 109 can include, but is not limited to, a binding, a port type, a message, a type, and the like. That is, interface definition 109 can specify requisite messages which can be used by the Web service associated with the process implementation.
In programmatic semantic search 110, the interface definition 109 can be conveyed to a semantic engine 112. Semantic engine 112 can utilize traditional and/or proprietary techniques to establish an ontology 113. One or more search parameters 116 can be extracted from the ontology 113. In instances where an ontology 113 is not available, known external service directories can be queried to obtain metadata which can be utilized to generate an appropriate ontology. Search parameters 116 can be employed to aid in locating existing services which can be useful to building out implementation 108 functionality. Search parameters 116 can include, but is not limited to, a keyword, a tag, a category, and the like. In one embodiment, search parameters 116 can include user specified options including a search depth parameter, a search string, and the like. In the instance, search parameters can utilize traditional Boolean operations and search depth options to automatically improve search results. For example, a search depth parameter can be specified in a numerical value (e.g., depth=3) permitting a user to search for specific process operations matching user specified criteria. It should be appreciated that search depth parameters can be specified using traditional and/or proprietary mechanisms. For example, the search depth parameter can be a search string keyword (e.g., depth: object). Search parameters 116 can be utilized by tooling engine 114 to perform query 118.
Query 118 can be conveyed to service directory 120 which can return a result set 119. Query 118 can include multiple search queries and/or parameters for identifying an appropriate service. In one instance, query 118 can be a SPARQL Protocol and Resource Description Framework (RDF) Query Language Query (SPARQL). Query 118 can be fully customizable utilizing user established settings, automatically established settings, and the like. In one instance, service directory 120 can be an internal service directory maintained within the tooling engine 114. In another instance, service directory 120 can be an external service directory communicatively linked to engine 114. For example, directory 120 can be a cloud based service registry accessible to tooling engine 114. Result set 119 can be a semantic search data set including identification of services 122 which match query 118 (e.g., search parameters 116). Result set 119 can be conveyed to engine 114 which can perform necessary actions to facilitate automated process implementation 108 assembly.
In service creation 140, result set 119 and metrics 142 can be utilized to create generated service 170. Engine 114 can employ metrics 142 to provide a ranked set 150 which can be an ordered instance of result set 119. For example, ranked set 150 can be a list of services 122 matching query 118 and/or search parameters 116. Metrics 142 can be one or more data sets of measures associated with a Web service. Metrics 142 can include, but is not limited to performance metrics, software metrics, and the like. For example, a metric 142 can be a popularity of a Web service based on service usage during a one week period. In one instance, ranked set 150 can be automatically generated and mapping 152 can be produced. In another instance, ranked set 150 can be automatically generated and await approval from a user before mapping 152 is produced. Metrics 142 can be automatically and/or manually conveyed to engine 114. For example, a user interface associated with tooling engine 114 can permit a developer to select specific metrics which can be used to aid in the creation of service 170.
One or more services 122 from ranked set 150 can be utilized to programmatically create mapping 152. Mapping 152 can be an artifact permitting association of service and/or service objects to an interface definition (e.g., interface metadata). In one instance, mapping 152 can be an Extensible Markup Language (XML) document for associating relevant service objects to implementation 108. Mapping 152 can be employed by engine 114 to provide generated code 154. Generated code 154 can be an entity including one or more source code documents. For example, generated code 154 can be a JAVA 2 ENTERPRISE EDITION source code document. Generated code 154 can be employed to create validation payload 160.
Validation payload 160 can be an artifact for verifying the appropriate operation of code 154. Validation payload 160 can include unit testing artifacts which can automate code 154 testing. In one instance, code 154 can be modified based on outcome of validation testing. That is, code 154 can be automatically tailored to fit specific requirements. In one embodiment, validation can be manually approved to enable user control of the flow. In another embodiment, one or more rules can be established to enable automation of approval.
When validation of code 154 is complete, generated service 170 can be created. Service 170 can be a completely functional Web service based on interface definition 109. In one embodiment, service 170 can conform to a Representational State Transfer (REST) architecture. In another embodiment, service 170 can conform to a Service Oriented Architecture (SOA). Service 170 can be optionally deployed based on engine 114 settings. In one embodiment, service 170 can be published to a service directory (e.g., stage publish 170).
In publish 170, engine 114 can publish service 170 to service directory 120. In one instance, a publish artifact can be conveyed to directory 120 to register service within a network. In one embodiment, publish artifact can be a WSDL document (e.g., interface definition 109). Service directory 120 can update services 122 to include generated service 170 availability. In one instance, ontology and metric information associated with the service 170 can be published to service directory 120. In the instance, the published data can be export to external registries (e.g., cloud service directory).
Drawings presented herein are for illustrative purposes only and should not be construed to limit the invention in any regard. It should be appreciated that disclosure can utilize external resources (e.g., semantic engine 112) to accomplish flow 100. It should be understood that stage 170 can be an optional phase of the disclosure. The flow 100 can be associated with traditional and/or proprietary Web service frameworks including, but not limited to, IBM WEB TOOLS PLATFORM, Apache Axis, Spring Framework, Web Services Invocation Framework, and the like. In one instance, flow 100 can utilize Java Application Programming Interface (API) for XML Web Services (JAX-WS) technologies.
FIG. 2 is a schematic diagram illustrating a method 200 for semantic analysis driven service creation in a multi-level business process in accordance with an embodiment of the inventive arrangements disclosed herein. Method 200 can be performed in the context of flow 100 and system 300. In method 200, a business process can be associated with a process implementation such as a Web service. The Web service can be automatically generated from a user provided interface definition. The generation can be aided in part by user input (e.g., user approval actions).
In step 205, a business process interface can be inputted within a Web service modeling tool. The business process can be manually and/or automatically inputted into the modeling tool. In one embodiment, a business process artifact conforming to a Business Process Modeling Notation (BPMN) format can be inputted into the modeling tool. The modeling tool can be a software program able to receive interface definition details associated with a process implementation. In one instance, the modeling tool can be an assisted creation tool (e.g., wizard) within an integrated development environment (IDE). For example, modeling tool can be a Web service creation screen of an IBM ECLIPSE IDE.
In step 210, an interface metadata (e.g., Extensible Markup Language document) can be generated from the interface. In one instance, metadata can include metrics associated with the interface. In one instance, a “summary” Extensible Markup Language document can be created. In the instance, the document can include context information about the interface extracted from metadata entered by a user, a list of vocabulary extracted from the interface definition, and the like. In step 215, the definition can be conveyed to a semantic analysis engine. In step 220, the definition can be analyzed by the semantic analysis and a set of search parameters can be generated.
In step 225, the search parameters can be utilized to identify existing services which can be utilized in Web service creation. In step 230, if services exist, the method can continue to step 240, else proceed to step 235. If a matching service is found, the service interface information can be retrieved from an internal service directory (e.g., directory 335). In one instance, service discovery can be performed utilizing Web Services Dynamic Discovery (WS-Discovery) communication protocol. When a matching service is not located, external registries can be queried for relevant artifacts. In step 235, the service can be built manually by an appropriate user. When a matching service is not located within external registries, the service can be defined manually. That is, the service can be new and user input via existing tooling is required to create the service. In one instance, a notification of service absence can be conveyed to one or more users. In the instance, tooling configuration can permit notification to be conveyed to an administrator, a developer, a development team, a project manager, and the like. For example, an email notification can be transmitted to a project team member when a service requires manual creation.
In step 240, existing services can be compiled into a ranked set. In one embodiment, the ranked set can include a score for each existing service identified. In the embodiment, the score can be automatically computed utilizing one or more rulesets. In one instance, the highest ranked service can be automatically selected to be utilized in the generation of the Web service. In step 245, appropriate artifacts can be selected from relevant services. In step 250, artifacts can be mapped to relevant interface objects. In step 255, generated service can be created based on mapping. In step 260, a verification payload can be generated. In step 265, validation services can be invoked to verify generated service. In one instance, one or more external services can be invoked to verify the generated service. In step 250, the service can be optionally published. In step 275, the method can end.
Drawings presented herein are for illustrative purposes only and should not be construed to limit the invention in any regard. Method 200 can be performed in parallel or serial. It should be appreciated that, method 200 can be performed in real-time or near real time. In one instance, method 200 can be triggered via a user interface functionality. For example, a file menu entry can permit assisted and targeted Web service development from an initial interface definition. It should be appreciated that method 200 can leverage semantic Web technologies to enable method to be enacted.
