A Review of Dynamic Web Service Description and Discovery Techniques

The increasing number of Web service providers over the Web has prompted the need for research in service description and discovery. The Web service requesters need tools, in order to search suitable services that satisfy the requester´s needs. The Web service discovery is defined as a mechanism that allows the service requester to gain an access to the service descriptions and make them available to the application at runtime for binding. The service requesters can retrieve a service descriptions at design time or at run time from the service description repository i.e. service registry like UDDI. The lookup mechanism must support a query mechanism to explore services based on the type of interface, the binding information (protocols), properties (QoS properties), the taxonomy of service and the business (provider) information etc. This paper reviews (and classifies) various architectures and matchmaking mechanisms defined in literature for the dynamic Web service discovery.
