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

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

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

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.

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

Conclusion
Discovery of Composable Web Services
April 21, 2023 Presented by Vassilya Abdulova 21
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.
