“…But, none of them presents such a focussed view on a components externally visible behavior as the communication graph does. Due to this representation, the comparison of behavior is more adequate w. r. t. the field of application than traces [24] or automaton [26].…”

Abstract. This paper is concerned with the application of Web services to distributed, cross-organizational business processes. In this scenario, it is crucial to answer the following questions: Do two Web services fit together in a way such that the composed system is deadlock-free? -the question of compatibility. Can one Web service be replaced by another while the remaining components stay untouched? -the question of equivalence. Can we reason about the soundness of one given Web service without considering the actual environment it will by used in? This paper defines the notion of usability -an intuitive and locally provable soundness criterion for a given Web services. Based on this notion, this paper demonstrates how the other questions could be answered. The presented method is based on Petri nets, because this formalism is widely used for modeling and analyzing business processes. Due to the existing Petri net semantics for BPEL4WS -a language that is in the very act of becoming the industrial standard for Web service based business processes -the results are directly applicable to real world examples.

“…First, element services provide basic business functions possible to autonomously be executed in an independent administrative domain, such as hotel reservation, goods tracking, credit card payment, and so on, while control services provide additional functions for the management of services such as service matchmaker [15,10], service performance validator [8], and so on. Each element service is assumed to have not only its own operations but also description of possible failures and the operation-coupled handlers.…”

Recently, the advent of Web services gets rid of the troubles in cooperating with other systems regardless of their underlying platforms. Web services can be composed dynamically on demand and possibly produce value-added services which are mesmerizing enterprises. For dependable execution of the composite services, many failure handling and recovery schemes have been proposed. However, those schemes lack in supporting specific handling of failures as an individual user desires.In this paper, we propose a service composition framework for user-specified failure handling in web services orchestration. In this framework, an instance of executable business process is dynamically generated from common business logic with failure handling specific to each user. We also design an XML expression of a user's failure acceptance specification, and an algorithm for automatically generating an executable business process embedding user-specified failure handling, with architecture of the composite service provider for applying our proposed framework. The comparison of properties between previous works and the proposed one in terms of failure handling is provided as well.

“…Service behaviors are not considered in these discovery approaches. Reference [16] attempts to find wanted business processes by directly matching message sequences, lack of a way to describe temporal properties. Activity sequences are considered in [2], and service discovery relies on pattern matching of two graphes which represent services.…”

Web service discovery based on behavior signatures

Web service discovery is a key problem as the number of services is expected to increase dramatically. Service discovery at the present time is based primarily on keywords, or interfaces of web services through the use of ontology. We argue that "behavior signatures" as operational level description should play an important role in the service discovery process. In this paper, we propose a new behavior model for web services using automata and logic formalisms. Roughly, the model associates messages with activities and adopts the IOPR model in OWLS to describe activities. A new query language is developed to express temporal and semantic properties on service behaviors. Query evaluation algorithms are developed; in particular, an optimization approach using RE-tree and heuristics is shown to improve the performance. Specifically, experimental results show that the use of RE-tree reduces query evaluation time by an order of magnitude and with heuristics it enhances the performance by two orders of magnitude. This is clearly an encouraging starting point.
