I'm trying to improve the semantic web services' discovery to satisfy better the user. For that, I choose to use OWL-S. So I created an ontology using Protégé then I generated semantic web services using OWL-S editor within Eclipse (these services have been in part generated automatically since they are already developed in Java). What I can't do now is the execution of these services: I don't know how to proceed. I need your help please, I didn't find good documentation or tutorials about the life cycle of OWL-S services. Could you please help me and suggest me some useful tools, tutorials..?
PS: do you think that OWL-S is still used or do you suggest something else? What is the most common way to develop semantic web services nowadays?
Thank you!
