Abstract

Method of computer-based detection of discrepancy between a user'"'"'s perception of web sites and an author'"'"'s intention of these web sites, wherein user interactions are gathered and combined with the content of individual web pages, the combination thereof is clustered topically, and a respective topical distance of the web pages is compared to a structural distance of the web pages, which results from the author'"'"'s elected arrangement of the web pages to each other, whereby the difference in both distances gives the discrepancy in the user'"'"'s perception and the author'"'"'s intention of the web pages, characterized in that at least parts of the text are extracted from the web pages for building keywords, which represent the contents of such web pages.

Claims

1. A method to detect a discrepancy between a user'"'"'s perception of web sites having web pages and an author'"'"'s intention for these web sites, comprising:

gathering user interaction information regarding how a user navigates between web pages;

building keywords based on text extracted from the web pages;

using the keywords to represent contents of the web pages;

topically combining the user interaction information with the contents of the web pages;

for each web page, determining a structural distance of the web page to other web pages based on how an author of the web page has arranged the web page with respect to other web pages; and

for each web page, comparing a topical distance of the web page to the structural distance of the web page, whereby a difference in the distances gauges the discrepancy between the user'"'"'s perception of and the author'"'"'s intention for the web page.

2. A method according to claim 1, wherein single occurring words, stop words and stems are filtered from the extracted text before the keywords are used to represent contents of the web pages.

3. A method according to claim 1, wherein navigational pages and crawlers are excluded when gathering user interaction information and representing contents of web pages.

4. A method according to claim 1, wherein the interaction information is stored in a user-session-matrix and the contents of the web pages is stored in a web-page keyword-matrix.

5. A method according to claim 4, wherein the user-session matrix and the web-page-keyword-matrix are multiplied for establishing a user-keyword-matrix.

6. A method according to claim 5, wherein user-sessions of the user-session-matrix are clustered by similar interests.

7. A method according to claim 6, wherein an initial clustering is made using a complete-linkage-method.

8. A method according to claim 2, wherein navigational pages and crawlers are excluded when gathering user interaction information and representing contents of web pages.

9. A method according to claim 8, wherein the interaction information is stored in a user-session-matrix and the contents of the web pages is stored in a web-page keyword-matrix.

10. A method according to claim 9, wherein the user-session matrix and the web-page-keyword-matrix are multiplied for establishing a user-keyword-matrix.

11. A method according to claim 10, wherein user-sessions of the user-session-matrix are clustered by similar interests.

12. A method according to claim 12, wherein an initial clustering is made using a complete-linkage-method.

13. A computer readable medium storing a program to control a computer to perform a method to detect a discrepancy between a user'"'"'s perception of web sites having web pages and an author'"'"'s intention for these web sites, the method comprising:

gathering user interaction information regarding how a user navigates between web pages;

building keywords based on text extracted from the web pages;

using the keywords to represent contents of the web pages;

topically combining the user interaction information with the contents of the web pages;

for each web page, determining a structural distance of the web page to other web pages based on how an author of the web page has arranged the web page with respect to other web pages; and

for each web page, comparing a topical distance of the web page to the structural distance of the web page, whereby a difference in the distances gauges the discrepancy between the user'"'"'s perception of and the author'"'"'s intention for the web page.
