[Question] Item filter by user

[aflyfish0329]

How can I configure Gorse to ensure that the recommended items for a user do not include items they have created themselves?

Thanks.

While there is no feature explicity for this pupore, I think you can send a read feedback for an item right after a user published it. But be aware that this may cause the system to think the user didn't like the content and don't suggest related items.

@erfansahaf Thanks your reply

I have another idea I want to implement. Perhaps I can add user_id in front of item_id to form user_id:item_id, and when doing offline recommendations in the worker, I can also add a check userId == strings.Split(s, ":")[0] during each excludeSet judgment before adding it to the candidates. What problems could this cause?
