Highlighting quoted passages in a hypertext system
View Patent ↗A method for highlighting quoted passages in a hypertext system. When a quotation in a reference document is selected by the user of the hypertext system, the source document for that quotation is retrieved from storage. The passage corresponding to the quotation is then located in the source document, and that quoted passage is highlighted in the initial display of the source document. Searching can locate a quoted passage even though it differs from the quotation. Optionally, differences between the quotation in the reference document and the quoted passage in the source document can be highlighted.
1. A method operating on a digital computer system, comprising:
displaying a reference document containing a quotation of a passage from a source document to permit the selection of the quotation by a user; and then
retrieving the source document containing the passage quoted in the quotation selected by the user; and then
locating the quoted passage in the source document; and then
displaying the source document, highlighting the quoted passage,
where the highlighting of the quoted passage is based on the result of the locating step and not highlighting previously in the source document.
2. A digital computer system programmed to perform the method of claim 1 .
3. A computer-readable medium storing a computer program implementing the method of claim 1 .
4. A method as in claim 1 , where the locating step utilizes an approximate matching technique to locate the quoted passage.
5. A digital computer system programmed to perform the method of claim 4 .
6. A computer-readable medium storing a computer program implementing the method of claim 4 .
7. A method operating on a digital computer system, comprising:
displaying a reference document containing a quotation of a passage from a source document to permit the selection of the quotation by a user; and then
retrieving the source document containing the passage quoted in the quotation selected by the user; and then
locating the quoted passage in the source document; and then displaying the source document, highlighting the quoted passage and indicating any differences between the quotation and the quoted passage,
where the highlighting of the quoted passage is based on the result of the locating step and not highlighting previously in the source document.
8. A digital computer system programmed to perform the method of claim 7 .
9. A computer-readable medium storing a computer program implementing the method of claim 7 .
10. A method as in claim 7 , where the locating step utilizes an approximate matching technique to locate the quoted passage.
11. A digital computer system programmed to perform the method of claim 10 .
12. A computer-readable medium storing a computer program implementing the method of claim 10 .
13. A method operating on a digital computer system, comprising:
displaying a reference document containing a quotation of a passage from a source document to permit the selection of the quotation by a user; and then
retrieving the source document containing the passage quoted in the quotation selected by the user; and then
locating the quoted passage in the source document; and then
displaying the source document, highlighting the quoted passage and indicating any differences between the quotation and the quoted passage by using one highlighting mode to highlight portions of the quoted passage that are contained in the selected quotation, and using another highlighting mode to display portions of the quotation that are not in the quoted passage,
where the highlighting is based on the result of the locating step and not highlighting previously in the source document.
14. A digital computer system programmed to perform the method of claim 13 .
15. A computer-readable medium storing a computer program implementing the method of claim 13 .
16. A method as in claim 13 , where the locating step utilizes an approximate matching technique to locate the quoted passage.
17. A digital computer system programmed to perform the method of claim 16 .
18. A computer-readable medium storing a computer program implementing the method of claim 17 .
