Abstract

A network device applies Hebbian-based learning to provide content recommendations in content-based social networks. The method includes obtaining customer activity data for a content-based social network; modeling the customer activity data as nodes and edges within the content-based social network, the nodes representing users and the edges representing connections between the users; assigning initial weights to the edges, that correspond to a connection strength, based on user-designated of relationships between the nodes; adjusting the initial weights in response to temporally correlated activity between the nodes from the customer activity data, to provide adjusted weights; identifying a content recommendation for a particular node based on an activity to access content by another node and one or more of the adjusted weights; storing a customer profile including the content recommendations associated with a node; and providing the content recommendation to a user device associated with the customer profile.

Claims

1. A method comprising:

obtaining, by a network device, customer activity data for a content-based social network;

modeling, by the network device, the customer activity data as nodes and edges within the content-based social network, the nodes representing users and the edges representing connections between the users;

assigning, by the network device, initial weights to the edges, that correspond to a connection strength, based on designated relationships between the nodes;

adjusting, by the network device, the initial weights in response to temporally correlated selections of a content item by two or more of the nodes, as indicated in the customer activity data, to provide adjusted weights, wherein the adjusting further comprises;

increasing one or more of the initial weights by an amount based on a difference between an expected outcome of the temporally correlated selections of the content item and an actual outcome of the temporally correlated selections of the content item, wherein the expected outcome includes selection of particular content by a particular node of the two or more nodes, which was previously selected by another node of the two or more nodes, within a time window;

identifying, by the network device, a content recommendation for the particular node of the two or more nodes based on an activity to access content by the other node and one or more of the adjusted weights; and

providing, by the network device, the content recommendation to a user device associated with the particular node.

2. The method of claim 1, wherein the customer activity data includes a record of selection of a content item from a catalog of available content items or a record of selection of a recommended content item.

3. The method of claim 1, wherein the edges further represent unidirectional connections between the users, and wherein assigning the initial weights further comprises assigning a weight based on:

bidirectional relationships from user-designated social media connections agreed upon by two of the users,

unidirectional relationships from user-designated social media connections of a single user to receive information from another of the users, or

non-designated relationships between the users.

4. The method of claim 1, wherein the adjusting further comprises:

decreasing one or more of the initial weights by an amount based on the difference between the expected outcome of the temporally correlated selections of the content item and the actual outcome of the temporally correlated selection of the content item.

5. The method of claim 1, wherein the expected outcome further includes:

failing to select the particular content by the particular node of the two or more nodes, which was previously selected by a another different node of the two or more nodes, within the time window.

6. The method of claim 1, further comprising:

storing, by the network device, a customer profile, including the content recommendation, associated with the particular node.

7. The method of claim 6, wherein the customer profile further includes a group association of the customer based on the adjusted weights.

8. The method of claim 7, wherein providing the content recommendation includes sending the content recommendation to all nodes within a same group association as a node that previously selected particular content.

9. The method of claim 6, wherein the customer profile further includes a connection strength threshold for notifications, and

wherein providing the content recommendation includes sending the content recommendation to all nodes that are connected to the particular node and have edges with adjusted weights that exceed the connection strength threshold.

10. A device comprising:

one or more memories to store instructions; and

a processor to execute the instructions to;

obtain customer activity data for a content-based social network;

model the customer activity data as nodes and edges within the content-based social network, the nodes representing users and the edges representing connections between the users;

assign initial weights to the edges, that correspond to a connection strength, based on designated relationships between the nodes;

adjust the initial weights in response to temporally correlated selections of a content item by two or more of the nodes, as indicated in the customer activity data, to provide adjusted weights, wherein the adjusting further comprises;

increasing one or more of the initial weights by an amount base on a difference between an expected outcome of the temporally correlated selections of the content item and an actual outcome of the temporally correlated selections of the content item, wherein the expected outcome includes selection by a particular node of particular content, which was previously selected by another node of the two or more nodes, within a time window;

identify a content recommendation for the particular node of the two or more nodes based on an activity to access content by the other node and one or more of the adjusted weights; and

provide the content recommendation to a user device associated with the particular node.
