Abstract: Methods, techniques, and systems for providing adaptive automated interaction capabilities for computer applications that request automated conducting of domain specific transactions via a domain specific online transaction website, e.g. an online-banking web site in a failure-proof manner. Particular methods, techniques and systems employ adaptive mixing of script-based and avatar-based execution entities for delegating sub-tasks and activities of a domain-specific transaction workflow for automated processing via a domain-specific online transaction website, the transactions being requested by a third party computer application and the domain e.g. pertaining to online banking.
