Where did you read this? These are probably terms that are defined within the context of the material that you have read - that does not mean that these terms are universally accepted.
My
guess would be:
Simple web service: One-off solution to either integrate two disparate systems within the company infrastructure or to establish an electronic link with one specific trading partner.
EAI Web Services: Systematic use of web services to integrate all heterogeneous systems within the company.
Example:
Composed Messaging with Web Services Business Web Services. This one could imply one of two totally different concepts.
Systematic use of web services for electronic interactions with most trading partners. Systematic implementation of business processes as services that can then be choreographed/coordinated (e.g. BPEL) into a WS-style SOA.
