Towards an Architectural Pattern for Automatic Web Service Discovery and Selection in Business Marketplace

The success of today enterprises depends on their capability to respond on demand to challenging customers´ request. At the same time, the enterprise marketplace is characterized by high dynamicity and heterogeneous requests. This makes difficult to provide in house cost-effective services able to meet them and, in many cases, the only solution is to aggregate different services at this purpose. In this context, the availability of an efficient service discovery mechanism is a key feature in order to enable the sketched context. In this paper, we present an architectural pattern for web service discovery following the principle of separation of concerns and based on the definition of discovery queries driven by the customers´ needs.
