Abstract

There are provided methods and systems for presenting a personalized aggregated search results page (SERP) to a user in response to a search query. The method can be executable at a server. The method comprises appreciating a user-specific aggregation preference parameter, the user-specific aggregation preference parameter having been generated based on at least one feature of the user'"'"'s search history; ranking a first general search result item and a first vertical search result item relative to each other based at least on the user-specific aggregation preference parameter, to generate a ranked order of search results items; and causing an electronic device associated with the user to display the ranked order of search results items within the SERP.

Claims

1. A method of presenting a search result page (SERP) to a user in response to a search query, the SERP including a first general search result item and a first vertical search result item, the method executable at a server, the method comprising:

appreciating a user-specific aggregation preference parameter, the user-specific aggregation preference parameter having been generated based on at least one feature of the user'"'"'s search history;

aggregating the first general search result item and the first vertical search result item into an aggregated set of search results;

ranking the first general search result item and the first vertical search result item relative to each other within the aggregated set of search results based at least on the user-specific aggregation preference parameter, to generate a ranked order of search results items; and

causing an electronic device associated with the user to display the ranked order of search results items within the SERP.

2. The method of claim 1, wherein:

the SERP includes a second vertical search result item; and

the first general search result item, the first vertical search result item, and the second vertical search result item are ranked relative to each other based at least on the user-specific aggregation preference parameter, to generate the ranked order of search results items.

3. The method of claim 2, wherein the first vertical search result item and the second vertical search result item are ranked together relative to the general search result item and displayed as a block within the SERP.

4. The method of claim 2, wherein the first vertical search result item and the second vertical search result item are ranked and displayed separately within the SERP.

5. The method of claim 1, wherein:

the SERP includes a second general search result item; and

the first general search result item, the first vertical search result item, the second vertical search result item, and the second general search result item are ranked relative to each other based at least on the user-specific aggregation preference parameter, to generate the ranked order of search results items.

6. The method of claim 1, wherein the first general search result item is ranked based on a general domain-ranking parameter, before said ranking based at least on the user-specific aggregation preference parameter.

7. The method of any one of claim 1, wherein the first vertical search result item is ranked based on a vertical domain-ranking parameter, before said ranking based at least on the user-specific aggregation preference parameter.

8. The method of claim 5, wherein the first general search result item and the second general search result item are ranked based on a general domain-ranking parameter, before said ranking based at least on the user-specific aggregation preference parameter.

9. The method of claim 5, wherein the first vertical search result item and the second vertical search result item are ranked based on a vertical domain-ranking parameter, before said ranking based at least on the user-specific aggregation preference parameter.

10. The method of claim 8, wherein the general domain-ranking parameter is based on a user-specific general ranking attribute.

11. The method of claim 8, wherein the vertical domain-ranking parameter is based on a user-specific vertical ranking attribute.

12. The method of claim 10, wherein any one of the user-specific general ranking attribute and the user-specific vertical ranking attribute is based on the same at least one feature of the user'"'"'s search history on which the user-specific aggregation parameter is based.

13. The method of claim 10, wherein any one of the user-specific general ranking attribute and the user-specific vertical ranking attribute is based on a second at least one feature of the user'"'"'s search history, said second at least one feature of the user'"'"'s search history being different from the at least one feature of the user'"'"'s search history on which the user-specific aggregation parameter is based.

14. The method of claim 1, wherein the at least one feature of the user'"'"'s search history includes at least one of user'"'"'s past preference for aggregated general content and vertical content, general content alone, or vertical content alone;

user'"'"'s past preference for obtaining results from a specific vertical domain; and

user'"'"'s intent for the search query.

15. The method of claim 1, wherein the at least one feature of the user'"'"'s search history includes at least one of a click-through rate;

a number of times a search result item was selected or clicked within a particular time period;

a dwell-time after clicking; and

whether a click on a result item was the last user action in a previous user session.

16. The method of claim 14, wherein user'"'"'s intent includes intent for a particular type of vertical content.

17. The method of claim 16, wherein the particular type of vertical content is video content, image content, commerce content, music content, weather content, geographic content, text content, dictionary content, events content, news content, or advertising content.

18. The method of claim 1, wherein the at least one feature of the user'"'"'s search history includes any one of query data;

vertical data;

web data; and

search-log data.

19. The method of claim 1, wherein the at least one feature of the user'"'"'s search history includes any one of aggregated search need;

certain vertical preference; and

vertical navigationality.

20. The method of claim 1, wherein the user-specific aggregation preference parameter has been generated using a Gradient Boosted Decision Tree-based algorithm.

21. The method of claim 1, wherein the user-specific aggregation preference parameter has been generated using a machine learning algorithm.

22. The method of claim 1, wherein said user-specific aggregation preference parameter has been generated prior to a point of time when the user has submitted the search query.

23. The method of claim 22, wherein said appreciating step comprises retrieving the previously generated user-specific aggregation preference parameter.

24. The method of claim 1, wherein said user-specific aggregation preference parameter has been generated at a point of time when the user submitted the search query.

25. The method of claim 1, wherein said user-specific aggregation preference parameter has been generated after a point of time when the user submitted the search query.

26. The method of claim 1, wherein said generating said user-specific aggregation preference parameter comprises accessing a log, said log including at least one feature of the user'"'"'s search history.

27. The method of claim 26, wherein said log is stored in association with the user'"'"'s log-in credentials.

28. The method of claim 2, wherein the first vertical search result item is generated by searching a first vertical domain, the second vertical search result item is generated by searching a second vertical domain, and the first vertical domain and the second vertical domain are not the same.

29. The method of claim 2, wherein the first vertical search result item is generated by searching a first vertical domain, the second vertical search result item is generated by searching a second vertical domain, and the first vertical domain and the second vertical domain are the same.

30. The method of claim 1, further comprising a step of determining that the first general search result item and the first vertical search result item are relevant to the search query, prior to said ranking.

31. The method of claim 1, wherein the first general search result item is one of a plurality of general search result items having been ranked according to a general search result ranking and the first vertical search result item is one of a plurality of vertical search result items having been ranked according to a vertical search result ranking.

32. A server configured for presenting a search result page (SERP) to a user in response to a search query, the server having a non-transient computer usable information storage medium that stores computer executable instructions, which instructions when executed are configured to render the server operable to execute the steps of:

appreciating a user-specific aggregation preference parameter, the user-specific aggregation preference parameter having been generated based on at least one feature of the user'"'"'s search history;

aggregating the first general search result item and the first vertical search result item into an aggregated set of search results;

ranking the first general search result item and the first vertical search result item relative to each other within the aggregated set of search results based at least on the user-specific aggregation preference parameter, to generate a ranked order of search results items; and

causing an electronic device associated with the user to display the ranked order of search results items within the SERP.
