Abstract

An electronic device for providing cross-domain recommendations includes a memory and at least one processor coupled to the memory. The at least one processor is configured to receive one or more notifications of at least one user activity in a content provider application, build at least one query based on the one or more notifications, and provide the at least one query to a database, receive at least one cross-domain action from the database. The at least one processor is also configured to generate at least one cross-domain recommendation based on the cross-domain action and instruct an application to display the at least one cross-domain recommendation.

First claim

What is claimed is:

1 . An electronic device, comprising:
a memory; and at least one processor coupled to the memory, wherein the at least one processor is configured to:
receive one or more notifications of at least one user activity in a content provider application;
build at least one query based on the one or more notifications;
provide the at least one query to a database;
receive at least one cross-domain action from the database;
generate at least one cross-domain recommendation based on the cross-domain action; and
instruct an application to display the at least one cross-domain recommendation.

2 . The electronic device of claim 1 , wherein the database is a graph database.

3 . The electronic device of claim 2 , wherein the at least one cross-domain recommendation includes two or more co-occurring cross-domain recommendations from one or more graphs in the graph database.

4 . The electronic device of claim 2 , wherein the at least one processor is further configured to provide information to update the graph database, wherein the information includes one or more user activities in one or more content provider applications.

5 . The electronic device of claim 4 , wherein the information to update the graph database causes the graph database to add one or more nodes to the graph database, wherein the one or more nodes are defined by one or more action results in the one or more content provider applications.

6 . The electronic device of claim 4 , wherein the information to update the graph database causes the graph database to delete one or more nodes from the graph database.

7 . The electronic device of claim 1 , wherein the at least one cross-domain recommendation is displayed on a host application surface in accordance with a display specification provided by the content provider application.

8 . A method, comprising:
receiving one or more notifications of at least one user activity in a content provider application; building at least one query based on the one or more notifications; providing the at least one query to a database; receiving at least one cross-domain action from the database; generating at least one cross-domain recommendation based on the cross-domain action; and instructing an application to display the at least one cross-domain recommendation.

9 . The method of claim 8 , wherein the database is a graph database.

10 . The method of claim 9 , wherein the at least one cross-domain recommendation includes two or more co-occurring cross-domain recommendations from one or more graphs in the graph database.

11 . The method of claim 9 , further comprising providing information to update the graph database, wherein the information includes one or more user activities in one or more content provider applications.

12 . The method of claim 11 , wherein the information to update the graph database causes the graph database to add one or more nodes to the graph database, wherein the one or more nodes are defined by one or more action results in the one or more content provider applications.

13 . The method of claim 11 , wherein the information to update the graph database causes the graph database to delete one or more nodes from the graph database.

14 . The method of claim 8 , wherein the at least one cross-domain recommendation is displayed on a host application surface in accordance with a display specification provided by the content provider application.

15 . A non-transitory computer readable medium embodying a computer program for operating an electronic device including a memory and at least one processor, the computer program comprising computer readable instructions that, when executed by the at least one processor, cause the electronic device to:
receive one or more notifications of at least one user activity in a content provider application; build at least one query based on the one or more notifications; provide the at least one query to a database; receive at least one cross-domain action from the database; generate at least one cross-domain recommendation based on the cross-domain action; and instruct an application to display the at least one cross-domain recommendation.

16 . The non-transitory computer readable medium of claim 15 , wherein the database is a graph database.

17 . The non-transitory computer readable medium of claim 16 , wherein the at least one cross-domain recommendation includes two or more co-occurring cross-domain recommendations from one or more graphs in the graph database.

18 . The non-transitory computer readable medium of claim 16 , wherein the computer program further comprises computer readable instructions that, when executed by the at least one processor, cause the electronic device to provide information to update the graph database, wherein the information includes one or more user activities in one or more content provider applications.

19 . The non-transitory computer readable medium of claim 18 , wherein the information to update the graph database causes the graph database to add one or more nodes to the graph database, wherein the one or more nodes are defined by one or more action results in the one or more content provider applications.

20 . The non-transitory computer readable medium of claim 18 , wherein the information to update the graph database causes the graph database to delete one or more nodes from the graph database.
