Objectives: The aim of this research is to discover and invoke the Web services dynamically according to the users’ requirement. This system resolves the unknown input parameters’ names and invokes the required services. Methods/ Statistical Analysis: The methodology used is retrieving the Web Service Description Language (WSDL) of the Web services from the online-search-engine according to the user request, extracting and storing only the required elements in Multidimensional Online Analytical Processing (MOLAP) Cubes, mining MOLAP records to fill the unknown WSDL parameters’ name and dynamically invoking the Web services. Findings: The WSDL is big in size due to its multi elemental structure and requires huge space and time for storing and processing. Hence MOLAP cubes are used to store only the required elements of the retrieved WSDL. Existing Web Service discovery methods are classified into several categories: Ontology-based approach, UDDI based approach, Semantic-Based approach, QoS-based approach, Information Retrieval Based approach, data mining based approach and link-based approach. The drawbacks of the existing systems motivated the proposed system to use the WSDL-based method and to use an online search engine for the discovery of Web services. The proposed system is designed and implemented by considering the dynamic nature of the Web services. The results of experiments justify that the proposed system satisfies the user requests with reduced consumption of bandwidth, CPU and storage space. The performance of proposed system is high compared to the existing non-MOLAP systems. Application/ Improvements: Developing bigger applications with fewer resources and lesser time. Reusability of existing procedures through Remote Procedure Call (RPC). Satisfaction of the user requests at high speed.Keywords

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.Keywords

This research focuses on dynamic Web service link searching using web scraping (WS). WS is method of extracting required contents from search engine results. The proposed system inputs the functional word to search engine and retrieves required Web services from search engine results. WS method retrieves the links of the Web Service Definition Language from which service and operation elements are extracted and processed to check suitability of Web services. Matched Web services will be clustered and invoked. This research is implemented using J2EE and remote Web services are executed according to user requirement. Analysis of results justified that this will be a suitable search method to search for remote Web services and to execute using open source software.Keywords
