Thank you very much. SemanticInterpretation is what I was looking for.
In my original post, I had an explanation of my problem, and now it seems to be completely blank. At least, I don't see any body to the post. I don't know what happened to it. Apologies for that.
Edited to add: If I Edit the original post, I see the text that was supposed to be there in the body. Not sure why it isn't appearing in the published post.
