Abstract

Abstract A method for extracting digests, reformatting, and automatic monitoring of structured online documents based on visual programming of document tree navigation and transformation is provided for structured online documents such as HTML, XML, SGML document, or any other document that has internal structure that can be represented by a tree. A digest of an online document is a collection of fragments of this document which are of interest to a user. The system is based on a technique whereby a user selects a fragment of an online document shown in a source window and copies this fragment to the target window that contains the reformatted digest. The system generates a sequence of web site navigation commands, online document tree navigation commands, and “Copy Fragment” commands that cause the assembly of the reformatted digest in the target window. The user can later ask the system to replay the generated commands, thus causing automatic creation of the reformatted digest of the changed version of the online document. Therefore, when content of the original document changes, the change is automatically propagated to the digest document. This allows implementation of a simple automatic monitoring of online documents or their reformatted digests. The digest document is usually much smaller than the original document, and usually it does not contain computationally intensive and bandwidth intensive multimedia elements such as graphics, sounds, applets, and scripts. This considerably lowers the bandwidth and processing power requirements for user agents that display document digests. Therefore digest documents can be displayed by user agents running on wireless and portable computing devices that have bandwidth and computational power limitations.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 137 words
A method of extracting a document fragment from a source document having a hierarchical internal structure, and displaying the document fragment in a target window, the method comprising the steps of: recording a script that finds the source document, navigates the hierarchical internal structure of the source document to find the document fragment, copies the document fragment, and displays the document fragment in the target window; saving the script on a computer-readable medium; and replaying the script using a computer to automatically redisplay the document fragment in the target window based on a current version of the source document, wherein the script includes navigation commands that lead from a root node of the hierarchical internal structure of the source document to a node of the hierarchical internal structure of the source document that represents the document fragment.
Claim 2
Independent Claim 137 words
A method of extracting a document fragment from a source document having a hierarchical internal structure, and displaying the document fragment in a target window, the method comprising the steps of: recording a script that finds the source document, navigates the hierarchical internal structure of the source document to find the document fragment, copies the document fragment, and displays the document fragment in the target window; saving the script on a computer-readable medium; and replaying the script using a computer to automatically redisplay the document fragment in the target window based on a current version of the source document, wherein the script includes navigation commands that lead from a root node of the hierarchical internal structure of the source document to a node of the hierarchical internal structure of the source document that represents the document fragment.
Claim 3
Dependent Claim 42 words
A method of extracting a document fragment from a source document as claimed in claim 1 , wherein the script further includes a copy fragment command that causes the contents of the selected document fragment to be displayed on the target window.
Claim 4
Independent Claim 155 words
A method of compiling a document digest by extracting at least one document fragment from at least one source document having a hierarchical internal structure, and displaying the document digest in a target window, the method comprising the steps of: recording at least a script that identifies the at least one document fragment to be copied from the at least one source document to the document digest; saving the script on a computer-readable medium; and replaying the script using a computer to automatically display the document digest in the target window based on a current version of the at least one source document, wherein the script includes navigation commands that lead from at least one root node of the hierarchical internal structure of the at least one source document to at least one other node of the hierarchical internal structure of the at least one source document that represents the at least one document fragment.
Claim 5
Independent Claim 155 words
A method of compiling a document digest by extracting at least one document fragment from at least one source document having a hierarchical internal structure, and displaying the document digest in a target window, the method comprising the steps of: recording at least a script that identifies the at least one document fragment to be copied from the at least one source document to the document digest; saving the script on a computer-readable medium; and replaying the script using a computer to automatically display the document digest in the target window based on a current version of the at least one source document, wherein the script includes navigation commands that lead from at least one root node of the hierarchical internal structure of the at least one source document to at least one other node of the hierarchical internal structure of the at least one source document that represents the at least one document fragment.
Claim 6
Dependent Claim 40 words
A method of compiling a document digest as claimed in claim 3 , wherein the script further includes a copy fragment command that causes the contents of the at least one document fragment to be displayed in the document digest.
