Abstract
A method and device for easily defining new information services for delivery to customers. The information to be delivered is extracted from information sources such as standard Internet web pages, databases, text files or proprietary data sources. The customer is provided with a list of accessible services, and may choose from among the services and may also specify delivery schedules of the information service. Information may be delivered to a cellular telephone display, or sent to a fax machine, beeper or to an e-mail server. The user may create a rule, composed of condition on the data in the page which has to met—for example a known text that has to be located in a known table cell and an action—for example to search for the next table in the page that meets the specified condition. This rule is maintained as part of the extraction template.
