Automated service composition has been investigated thoroughly during the last five years. Although it promises to alleviate the difficulties of manual service composition, it will only work if complete and correct service specifications are available. In this paper, we present a third approach – semi-automated composition – based on three mixed initiative features which we have derived from an industry case study with SAP. These features, filter inappropriate services, check validity, and suggest partial plans, are definded on the basis of a common formal model. Related approaches, in contrast, are limited to supporting individual mixed ini-tiative features. To show the applicability of our approach, we have developed a prototypical implementation. Our re-sults show that our mixed initiative approach significantly eases the modeling of service compositions. 1

Abstract. When creating service compositions from a very large number of atomic service operations, it is inherently difficult for the modeler to discover suitable operations for his particular goal. Automated service composition claims to solve this problem, but only works if complete and correct ontologies alongside with service descriptions are in place. In this paper, we present a semi-automated modeling environment for Web service compositions. At every step in the process of creating the composition, the environment suggests the modeler a number of relevant Web services. Furthermore, the environment summarizes the problems that would prevent the composed service from being invocable. The environment is also able to insert composed services into the composition at suitable places, with atomic services producing the required data artifacts to come to an invocable composition. Our results show that this mixed initiative approach significantly eases the creation of composed services. We validated our implementation with the leading vendor of business applications, using their processes and service repository, which spans across multiple functional areas of enterprise computing. 1

The process of selecting Web services from a large number of potential Web services available on the Web is a challenging task for users engaged in Web service composition. Our work is devoted to resolving this issue by suggesting Web services to the user. Our suggestion algorithm ranks all the available services for the user based on the semantic annotations of a service’s inputs, outputs and functionality, as well as pre-conditions and effects, if available. This paper presents multiple algorithms for making suggestions during Web service composition. These algorithms extend traditional Web service discovery algorithms; in particular, they include new techniques for ranking the effectiveness of data mediation.

Abstract: Despite the fact that researchers agree on the importance of enterprise models to an organization’s success, the knowledge about how tohandle problems where models have to be compared or integrated is still fuzzy and vague, and there is little agreement regarding compositional facets. Highly interesting is the interaction between models in shared modeling projects —e.g.between requirement models and service implementations in aservice-oriented architecture (SOA). This article highlights an approach that allows to prevent integration conflicts in conceptual models already during the modeling phase. The influence of this approach on conceptual modeling and its use in intra-organizational collaborations is investigated. We show the inherent complexities of model-mediated interactions between domain experts and IT-service developers. It is suggested that at an early stage of the modeling process the use of guidelines has an substantial benefit for avoiding integration conflicts in conceptual models. Furthermore, due to the way how the approach bridges the semantic gap, changes of business requirements as well as technical implementation restrictions influence each other. This results in an ongoing system development process that can be interpreted as apermanent management of application systems. Our results contribute to model-based management theories that have so far neglected the distributed construction of conceptual models. 1
