Abstract

Method and system for content conversion of electronic data using data mining. A user is able select one or more hypertext elements from one or more hypertext electronic document for conversion based on user conversion preferences. For example, a user selects one or more display elements from one or more “web-pages” from the World-Wide-Web on the Internet or an intranet. The hypertext elements are extracted from one or more hypertext electronic documents and converted into a format suitable for display on a user device based on user conversion preferences. Selected hypertext elements are extracted and converted using data mining conversion operations. The data mining conversion operations allow a user to extract only desired display information displayed from a hypertext element and convert the display information into a format different than that defined for the original electronic document. The converted display information is appropriate for a user device such as hand-held, wireless phone, personal digital assistant, or other device.

Claims

1. In a first network with a plurality of network devices connected to a second network with a plurality of network devices, a method of content conversion for display on a first network device on the first network, comprising:

receiving a first hypertext electronic document on a second network device on a first network, from a third network device on a second network;

creating a document object model from the first hypertext electronic document;

extracting one or more selected hypertext elements from the document object model using one or more data mining expressions from a data mining conversion language comprising a set of methods operable to identify at least one of the one or more hypertext elements in the hypertext electronic document;

converting one or more extracted hypertext elements using one or more data mining operations from the data mining conversion language to generate one or more conversion variables corresponding to the one or more extracted hypertext elements, respectively;

creating a second hypertext electronic document including the extracted hypertext elements on the second network device based on a document template including the data mining conversion variables, wherein the data mining conversion variables are identifiable in the document template by a prefix including “

&

%”

characters; and

sending the second hypertext electronic document to the first network device on the first network for display.
