Multi-objective Service Similarity Metrics for More Effective Service Engineering Methods (Short Paper)

The usage of single-objective similarity functions in engineering tasks of service-oriented software may reduce their effectiveness, since a single similarity value can be misleading. In particular, a single similarity value cannot be clearly interpreted, since it hides the values of its individual objectives. The state-of-the-art approaches, which use service similarity functions, typically rely on single-objective functions. Going in a complementary direction, we propose the usage of multi-objective functions for calculating service similarity. We formally define such a function and we provide emerging results, which show that the effectiveness of service engineering tasks can be improved by using multi-objective functions.
