  1. CMPE588 Term Project Presentation Discovery of Composable Web Services Presented by: Vassilya Abdulova

  2. Discovery of Composable Web Services Introduction

  3. Introduction • Aim of the project: • Application • extracting relationships between Web Services • deciding whether services are composable • Parts of the project: • creating Web Services using OWL-S • writing Java code for the extraction of relationships between Web Services • JSP (Java Server Pages)/HTML code development of user interface Presented by Vassilya Abdulova

  4. Discovery of Composable Web Services Web Services using OWL-S

  5. Developed Web Services • Book Finder WS • takes name of the book as an input and returns ISBN of the book • Book Price WS • takes ISBN of a book as an input and returns the price of the book Presented by Vassilya Abdulova

  6. Developed Web Services • Car Finder WS • takes make and model of the car as an input and returns the information about the car • Car Price WS • takes information about the car as an input and returns the price of the car • Currency Converter WS • takes currency and price as an input and returns converted price as an output Presented by Vassilya Abdulova

  7. OWL-S • set of ontologies for describing web services • consists of three main upper ontologies • Profile • essentially used for describing the non-functional properties (service name, category, etc.); • Process • gives a detailed description of a service operation, its inputs and outputs • Grounding • provides details on how to interoperate with a service via messages.

  13. Discovery of Composable Web Services Composability of Web Services

  14. Composability of Web Services Presented by Vassilya Abdulova

  15. Example Scenario Presented by Vassilya Abdulova

  16. Discovery of Composable Web Services Web Application

  17. Web Application • Developed using Java Server Pages and HTML • JSP technology • separates user interface from content generation • enables designers to change the overall page layout without altering the underlying dynamic content Presented by Vassilya Abdulova

  18. Web Application in JSP Presented by Vassilya Abdulova

  19. Web Application in JSP Presented by Vassilya Abdulova

  20. Discovery of Composable Web Services Conclusion

  21. Conclusion • Successfully implemented an application that extracts relationships between Web Services and decides on whether these services are composable. • Developed five Web Services using OWL-S and tested their composability using the developed application • Developed a web application using JSP, which allows users to select some Web Services and provides composability report to the user.
