Research Problem

Due to the heterogeneity, both structural and semantic, in QoS term description which is inherent in the service and cloud world, there is a need for introducing a semantic language which is able to cover the non-functional service description. As such, the use of such language will enable reaching better accuracy levels in service discovery and composition. Apart from non-functional service profiles and requests, this language should be able to specify SLAs in the way that extends the current state-of-the-art. This means that it should be complete enough in order to cover all information required for supporting the management of all service lifecycle activities.

The required language should be able to also specify KPIs as well as link them to goals in order to support BPaaS evaluation as well as goal analysis enabling broker to inspect whether their strategic, tactical and operational goals are satisfied. The current set of languages employed for this purposes suffer from the following drawbacks: (a) they are not rich or complete enough to cover the respective domain; (b) they are mapped to a quite technical level which is not suitable for business experts; (c) they are not able to exploit different information sources, even external to the respective BPaaS (management) system; (d) in some cases, they are not linked to goals.

Solution Approach
