Comparing text values from columns in two different Tables

I have two datasets:

webfact

dimSegments

When someone selects Fresh or Frozen from dimSegment, I expect to see this:

When someone selects US from dimSegment, I expect to see this:

dimSegments contains hundreds of Segment and Tag combinations so I would prefer not to manually assign each condition individually. Is there a way to do this via DAX or Power Query? I'm even open to parameters nested in SQL statements via Advanced Editor.

This is obviously not correct but this is what my brain has conjured up: 
if Text.Contains(webfact.Tags_Fact, dimSegments.Tags_Dim) then dimSegments.Segment
