Abstract

A server improves the ranking of search results. The server includes a processor and a memory that stores instructions and a group of query themes. The processor receives a search query containing at least one search term, retrieves one or more objects based on the at least one search term and determines whether the search query corresponds to at least one of the group of query themes. The processor then ranks the one or more objects based on whether the search query corresponds to at least one of the group of query themes and provides the ranked one or more objects to a user.

Claims

1. A method, implemented by a computer device, for providing search results, comprising:

receiving a search query;

retrieving one or more objects in response to the search query;

automatically determining whether the search query corresponds to at least one query theme of a group of query themes;

determining whether any of the one or more objects relates to a list of favored or non-favored sources;

ranking the one or more objects based on a result of the determination of whether the search query corresponds to at least one query theme and the determination whether any of the one or more objects relates to the list of favored or non-favored sources; and

providing the ranked one or more objects to a client.

2. The method of claim 1 wherein the objects include web pages.

determining a score for those objects that are unrelated to the list of favored or non-favored sources using a first group of parameters,

determining a score for those objects that relate to the list of favored or non-favored sources using the first group of parameters and an editorial opinion parameter, and

ranking the objects based on the determined scores.

4. The method of claim 3 wherein the editorial opinion parameter causes the rank of those objects corresponding to favored sources to be increased and a rank of those objects corresponding to non-favored sources to be decreased.

5. The method of claim 1 wherein the automatically determining includes:

determining whether the search query corresponds to a query rule associated with each query theme.

6. The method of claim 1 wherein each query theme is classified into a first set of topics, and

wherein the automatically determining includes:

classifying the search query into a second set of topics, and

determining that the search query corresponds to a query theme when the second set of topics relates to the first set of topics associated with that query theme.

provide the ranked one or more objects to a client.

15. The server of claim 14 wherein, when ranking the one or more objects, the processor is configured to:

determine a score for those objects that are unrelated to the list of favored or non-favored sources using a first group of parameters,

determine a score for those objects that relate to the list of favored or non-favored sources using the first group of parameters and an editorial opinion parameter, and

rank the objects based on the determined scores.

16. The server of claim 15 wherein the editorial opinion parameter causes the rank of those objects corresponding to favored sources to be increased and a rank of those objects corresponding to non-favored sources to be decreased.

17. A method comprising:

developing one or more query themes;

identifying, for each query theme, a first set of objects as favored objects;
