Universal Recommender date boosts

[Tom McCaul <to...@tomandco.co.uk>]

Hi,

I'm setting up UR to return an ordered list of items for a category by
popularity but I wanted to boost new in items.

So far, I'm using an attribute to create a boost for those new products but
this isn't the most ideal set up.  I'd prefer for the boost to be weighted
over time, so on day 1, the product receives the biggest boost and by day
28 (just before it's no longer considered new) it's at its lowest.

Does anyone have any suggestions how I could best approach this?

Thanks,
Tom

Create categorical date ranges and attach them to items. They will be "0-10 days”, "11-20 days” etc. Something that encodes how far back from today the data is. This will, of course need to be updated periodically with a property change event.

Then in your engine.json or query boost "0-10 days” with a bias of something above 1 like 10, and “11-20 days” by something less like 5.

If you limit the number of user history events you will get a recency effect also. This is discussed in actionml.com/ur-config <http://actionml.com/ur-config>, look for maxQueryEvents. This will allow you to look for the most current user intent, it will not explicitly boost new things. IMHO It is likely to have a better effect on your KPIs than an explicit boost but you’d have to A/B test to be sure.
