Context matters. Without it , its going to go haywire.

Eric, I have being in this situation and my experience has being that
its a super hard thing to do and the results are pretty bad in my
experience anyway.

Secondly, Its very hard to map between DDC and LCSH, even at the
highlest level.

I am sure if enough resources are put into it, you should be able to
get somewhat of a mapping, but is worth all that effort and resource?
for a somewhat of a mapping?

You can however refer to the  mapping from between DDC and LCSH at
classificationweb.net.

That is work done by professional librarians and even this does not do
a good mapping as far as I can see.

What is the mapping based on?
