Method and system for online user profiling

A non-transitory, computer-readable medium having information recorded thereon for online user profiling, which, when read by at least one processor, effectuates operations comprising:

• determining a social media network including a first user and other users in a social graph associated with the first user;
• obtaining first web-based content with which the first user interacts;
• extracting, from the first web-based content, a first link pointing to second web-based content;
• obtaining third web-based content with which the other users interact;
• extracting, from the third web-based content, a second link pointing to fourth web-based content;
• extracting, based on a content analysis platform model, features from the first and second web-based content and features from the third and fourth web-based content, wherein the extracted features comprise publishers of the first, second, third, and fourth web-based content;
• scoring each of the publishers based on relevance of the publisher to each of the first, second, third, and fourth web-based content;
• generating, for the first user, a first user profile based on the scoring;
• generating, based on user profiles of the other users and weights assigned to the publishers, a baseline user profile indicative of popularity of one or more of the extracted publishers in the social media network;
• adjusting the first user profile based on the baseline user profile;
• updating the first user profile based on a time-decay model, wherein historical weights assigned to the publishers are updated based on the time-decay model, and the time decay model includes a time-decay factor that reduces the historical weights in an exponential manner with respect to a time instance at which the first, second, third, and fourth web-based content are obtained;
• generating, based on the updated first user profile, a personalized content recommendation;
• and
• presenting, via an application running on an electronic user device associated with the first user, the personalized content recommendation to the first.

A system for online user profiling, the system comprising:
