my definition is it's a service made available using Web based
technologies targeted at computer, as opposed to human, agents.

Some attempts at definitions:

http://www.w3.org/2002/ws/
http://en.wikipedia.org/wiki/Web_services
http://ws-i.org/about/Default.aspx
http://msdn.microsoft.com/webservices/
Google until your blue in the face ..

Web services are synonymous with SOAP, WSDL and UDDI in many
peoples' eyes, though they've taken so long to arrive
that the marketeers are busy re-branding it 'SOA', I
guess SOAP is now Service Oriented Architecture Protocol :-)

Sure, why ever not? It's the service that's important, not
how you elect to describe, catalogue or sell them.
