Domain expertise determination
View Patent ↗A user's domain expertise may be estimated through several factors by monitoring different aspects of a user's interaction with a web browser. Based on the user's domain expertise, search results may be presented to the user that is commensurate with their expertise, resulting in a more efficient and productive on line session. A user's expertise in a knowledge domain may be determined from the user's behavior, including analyzing search queries, monitoring how the user navigates between and through websites, and analyzing the specific cites visited. As a user interacts with a browser, the user's estimated domain expertise may be updated and used to provide appropriate and useful search results. In many embodiments, a user may have different expertise levels for different technical domains.
1. A method comprising:
monitoring a web browser session by a user;
identifying a search query submitted by said user, said search query generating a set of search results;
identifying a web page selected by said user from said search results;
examining said web page and identifying a set of technical words in said web page;
comparing said technical words to a technical lexicon, said technical lexicon comprising a user expertise level corresponding to said technical words; and
determining a user expertise level for said user based on said technical words in said web page.
2. The method of claim 1 further comprising storing said user expertise level.
3. The method of claim 2 further comprising updating said user expertise level based on a subsequent web browser session.
4. The method of claim 1 , said search results comprising an expert grouping.
5. The method of claim 1 further comprising:
determining an expertise level for each of said search results; and
ranking said search results by said expertise level.
6. The method of claim 5 further comprising:
displaying a subset of said search results having an expertise level corresponding to said user expertise level.
7. The method of claim 1 further comprising:
determining a visit length for said selected site; and
updating said user expertise level based on said visit length.
8. The method of claim 7 , said selected site being browsed to by said user.
9. The method of claim 1 further comprising:
monitoring said web browsing session to determine a branchiness factor for said session; and
updating said user expertise level based on said branchiness factor.
10. A system comprising:
a processor;
system memory; and
one or more computer storage media having stored thereon computer-executable instructions representing:
a lexicon comprising technical words, said technical words being related to a technical domain; and
an expertise rating system that:
receives a search result comprising a plurality of web sites generated in response to a query; and
determines an expertise rating for each of said web sites by identifying one or more technical search terms from said web sites;
identifies a first web site selected by a user; and
determines a user expertise level based on said expertise rating for said first web site.
11. The system of claim 10 , said expertise rating system that further updates an expertise rating for a particular user.
12. The system of claim 11 , said expertise rating being stored on a local storage device.
13. The system of claim 11 , said expertise rating being stored on a remote storage device, said expertise rating being stored without any personally identifiable information.
14. The system of claim 13 , said expertise rating being stored on a remote storage device, said particular user having given permission for said expertise rating to be stored.
15. The system of claim 10 , said user expertise rating being determined for a specific domain.
16. A method comprising:
monitoring a web browser session by a user;
determining a first user expertise level associated with a first domain for said user;
identifying a website browsed to by said user;
determining an expertise level and a first technical domain associated with said website by associating said first user expertise level and said first technical domain; and
storing said first expertise level and said first technical domain for said website.
17. The method of claim 16 further comprising:
receiving a query from a second user, said second using having a second user expertise level in said first domain;
determining that said query is related to said first domain, said query returning said website;
determining that said second user expertise level is similar to said first expertise level and presenting said website to said second user.
18. The method of claim 16 , for each of a plurality of domains, said user having a different expertise level.
19. The method of claim 16 , said website being browsed to by said user from a group of search results.
