Group recommendation for user-generated content

A system comprising:

• a memory comprising instructions;
• and
• one or more computer processors, wherein the instructions, when executed by the one or more computer processors, cause the system to perform operations comprising:
• detecting a post of a user being added to an online service;
• determining post interest scores for the post, the post interest scores being for a plurality of interests, each interest being associated with a topic;
• calculating a match score for a plurality of groups based on the post interest scores and group interest scores;
• using an intent machine-learning (ML) model to calculate the group interest scores, wherein the intent ML model is trained with training data based on past content and assigned labels for corresponding intents;
• determining whether to recommend a group, from the plurality of groups, for including the post of the user in a feed of the recommended group based on the match score;
• and
• within an order or less of a hundred milliseconds of the post of the user being added, causing, by a real-time nudge system, a presentation of the recommended group based on the determined recommendation.
