BPEL Processes Matchmaking for Service Discovery

The capability to easily find useful services software applications, software components, scientific computations becomes increasingly critical in several fields. Recent works have demonstrated that this approach is not sufficient to discover relevant components. In this paper we argue that, in many situations, the service discovery should be based on the specification of service behavior. The idea behind is to develop matching techniques that operate on behavior models and allow delivery of partial matches and evaluation of semantic distance between these matches and the user requirements.

Consequently, even if a service satisfying exactly the user requirements does not exist, the most similar ones will be retrieved and proposed for reuse by extension or modification.

To illustrate Web services provision and provide application requirements for the research issues that we focus on in this survey, we describe here a classic scenario — travel agency — in which a customer makes a plan for his trip through a travel agent. Suppose Bob wants to plan a trip with his family to celebrate his birthday. At first, he and his family come to an agreement that the scenic spot should be close to mountains and not be too hot, and they can go there directly by plane.

Then, Bob sends a travel agent these requirements based on which candidate scenic spots can be searched. After finding these scenic spots, the agent contacts a flight company to see whether enough tickets are available. If not, it notifies Bob the unfortunate result; otherwise, it tells Bob to select and confirm one scenic spot and corresponding flight tickets. As soon as Bob acknowledges the initial plan, the agent starts to confirm the expected flight.

After that, it reserves hotel rooms nearby and tickets for the scenic spot. Finally, Bob is informed of the plan details including flight tickets, scenic spot tickets, and hotel rooms.

This work addresses the question of how to efficiently find business partners with matching business processes. In particular, the input business process enforces that some parts of the business process be mandatory. Current Web service standards around UDDI do not address this problem as they are limited to atomic service discovery.

BPEL which is currently used to express business processes in Web service environments does not have a solid formal model, thus lacks formal semantics for querying business processes. A formal model is required to express business processes and enable their querying.

The problem addressed in this dissertation can be stated as follows: given as a query, a business process description within a Web service infrastructure, efficiently find business processes from a large repository that complementarily support the input query. In particular, the input business process enforces that some parts of the business process be mandatory.

For example, a buyer organization using RosettaNet PIPs and the corresponding data dictionary might want to find suppliers that use the same RosettaNet standard that fulfill his business process. In this case, for instance, a mandatory cancellation procedure of the processing would be executed after the order had been placed with the supplier. This means that a formal model is required to express business processes and to enable their querying.

Based on this formal model, appropriate indexing techniques are needed for efficient querying in large service repositories. A business process can be described as a set of message sequences each representing a potential execution sequence of the process. Based on this model, business processes are queried by finding matching business processes within the repository; the matching operation can be defined by computing a common set of message sequences covering the mandatory parts.

Based on this formal model, appropriate indexing techniques are needed to efficiently query large service repositories. In this work a formal model and algorithms for indexing and querying business processes are presented. This work should help shed some light on how to automate the discovery of compatible business partners on the basis of their business processes. It is suitable for professionals and researchers involved in business process modeling, engineering and implementation.
