Relevancy-ranking LCSH?

I just wrote up a blog post about trying to tease relevancy ranking from LCSHs:

I wonder if anyone has made, seen or can think of any good methods to
do it. So far I've only seen non-ranked and popularity-ranked results.
In the blog post I talk about playing around with how LCSHs reinforce"
each other statistically, but I couldn't get the algorithm to produce
good results more than sporadically.

I'm not sure if this is a cataloging or a coding. Maybe that's the point.
