Alert Notification as a new model of internet-based transactions

The newly proposed Alert Notification Service (ANS) represents a web service that automatically visits all requested web sites selected by a certain user and alerts the user when a certain keyword phrase has been changed. This saves users' time and effort by reducing the repeatedly visiting multiple web sites looking for some specific information or keywords. In comparison with other systems of the same kind, the ANS has a more intuitive user interface, and does not use only RSS for news feeds. It targets users who need to be notified for a certain change or appearance, as well as cloud service providers who would want to build a push functionality for standard web sites that do not support this technology. In this paper we present a new model of Internet-based transactions. It involves an automated intelligent agent in the communication between the user and server, which performs certain frequent user activities by visiting web pages on Internet. We also discuss the benefits of building and using such a system fully working as a service.
