Study survey of service discovery using perdurant ontology

Service discovery is a mechanism for finding services, the existing service discovery mechanisms offer low retrieval precision and recall. The current problem with service inventories such as UDDI is the retrieval process which associated with the search engines that support only syntactic, keyword-Oriented search. Many researchers talked about that and some of them introduce the use of semantic service discovery mechanisms to improve the quality of result. The key to searching service inventories is to find ways to represent them in a way that can be exploited by one of the standard methods like Google type search. In our work we introduce a review of ontology and mechanisms used there. The main concern is service inventories at design time by designing ontology and produce queries at run time to specify how to access the services by using TripAdvisor website as a concrete case study.
