Abstract In software development, crosscutting concerns, such as security, audit, access control, authentication, logging, persistence, transaction, error handling etc. can be modularized using the aspect-oriented paradigm. In business process modeling, aspects have been used to reduce visualization complexity, increase reuse and improve model maintainability. There are techniques which address aspects in modeling and implementation phases of business process; however, these techniques adopt different semantic representations, hindering the integration of these phases into the BPM lifecycle. This work proposes an architecture for service discovery capable of selecting web services that implement crosscutting concerns and meet the goals established in the aspect modeling phase, executing them accordingly with a prioritization.

was performed. Afterwards, the proposal was evaluated by means of an experiment. The results suggest that the definition of an operational goal enables the business specialists to concentrate on the modeling of the aspect without necessarily concerning its implementation, since a proper option for implementation is discovered during the execution of the process.

1 Introduction The aspect-oriented paradigm (Kiczales et al. 1997) brings several advantages for software development, such as the reduction of scattered codes, transparency of the responsibilities of each module, and independence of modules, as well as facilitating the application evolution with low coupling between the modules, and the code reusability. The business process management (BPM) community has been actively studying the application of this paradigm in all phases of the BPM life cycle in order to modularize crosscutting concerns that are scattered and tangled within process models (Cappelli et al. 201
