Efficient Matchmaking of Business Processes in Web Service Infrastructures

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 do so, we reduce the problem of behavioral matching to a graph matching problem and we adapt existing algorithms for this purpose. A prototype is presented which takes as input two BPEL models and evaluates the semantic distance between them; the prototype provides also the script of edit operations that can be used to alter the first model to render it identical with the second one.

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.

Healthcare is often perceived to lag behind other industry sectors in its uptake and adoption of new technology. The main purpose of eHealth is to provide better use of information in health care settings, to improve the quality of patient care and the efficiency of clinical processes. Many situations exist where the use of eCommerce principles would be appropriate to establish new eHealth solutions, and these warrant extensive research investigation.

Services Computing has been described as a “cross-discipline that covers the science and technology of bridging the gap between Business Services and IT Services” Site 1. This role is supported by Web services and service-oriented architecture SOA , business consulting methodology and utilities, business process modelling, transformation and integration. The goal of Services Computing is to enable IT services and computing technology to perform business services more efficiently and effectively.

Opportunities abound for the unique aspects of healthcare to drive fundamental computing and IT research together with leading applied research within the healthcare domain that could potentially be reapplied to areas outside of healthcare. This special issue contains articles addressing eHealth and Services Computing in Healthcare from several different perspectives.

The first three articles set the scene for research within this domain by focusing on business process modelling within healthcare and e-health, otherwise known as patient flow or patient journey modelling. While many healthcare organisations are utilising Lean Thinking Site 2 based approaches, these research articles show that improvements can be made to these initiatives through approaches that better support the nuances of healthcare when compared to the retail and manufacturing sectors for example.

In this paper, we argue that in several applications services having multiple and dependent operations and scientific workflows , 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 approximate matches and evaluation of semantic distance between these matches and the user requirements. To do so, we reduce the problem of behavioral matching to a graph matching problem and adapt existing algorithms for this purpose.

BPEL Processes Matchmaking for Service Discovery

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.

Toggle navigation Boston University Libraries. Link Network. This item is available to borrow from all library branches. Editor Cabral, Liliana. Martin, David. Cabral, Liliana. Summary Over the last decade, a great amount of effort and resources have been invested in the development of Semantic Web Service SWS frameworks.

Numerous description languages, frameworks, tools, and matchmaking and composition algorithms have been proposed. Nevertheless, when faced with a real-world problem, it is still very hard to decide which of these different approaches to use. In this book, the editors present an overall overview and comparison of the main current evaluation initiatives for SWS. The presentation is divided into four parts, each referring to one of the evaluation initiatives.

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. 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.
