Survey on discovery of web services

Abstract

Objectives: This paper is focused on survey of various discovery methods of web services. Web service discovery and service composition play an important role in the area of services computing. Methods/Statistical Analysis: There are many important research topics related to web service discovery and are classified into two categories: the syntactic web service discovery and semantic web service discovery. Syntactic based discovery involves the techniques of search based on Universal Directory Description Interface (UDDI), search based on text document, search on schema matching and software component matching. Semantic-based search is mainly based on ontology. Findings: The discovery of web service is a hot research topic for the past several years. Searching for similar web services and selecting them according to the user requirement is a key factor to satisfy consumer requests. Because of the absence of UDDI, it is not possible to get the link of the WSDL and also it is not possible to get Quality of Service (QOS) parameters unless the web service is executed. It is necessary to search the each request dynamically using search engines because of dynamic nature of the web services and due to absence of UDDI. Application/Improvements: This paper is focused on brief discussion of result of conducted research based on a dynamic search which is different from the methods specified in the literature review. It is concluded from the result that average search speed of different Web service’s discovery system is different for different types of searches.
