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. The business process matchmaking semantics can be formalized by modelling business processes using an enrichment of finite state automata FSAs with propositional logical expressions.

A business process matchmaking is formally defined as the non-empty intersection of aFSAs, covering mandatory parts of the business process description. Computing the intersection of aFSAs is computationally expensive being more than quadratic on the number of states and transitions. Further, sequentially scanning large service repositories to find matching business processes will not scale even if individual query operations were simple.

The traditional way to speed-up query performance operations in databases is to use indexes.

problem as they are limited to atomic service discovery. BPEL which is currently used to express business processes in Web service.

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.

Thesis Title: Behavioral matchmaking for service retrieval; Supervisor: Mokrane BOUZEGHOUB – Daniela Ranking BPEL Processes for Service Discovery.

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.

Service discovery is the process of locating existing (aka service matchmaking) encompasses (a) the service orchestrations in BPEL as the semantic service.

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.
