Fair point. "Abstract" might be better. It embodies the information-/implementation-hiding goal of this technique.

Abstractions still require names, and the names should be meaningful (not easy: "naming things is one of the hardest things to do in software development"), at least to the development team (hate to keep rattling off platitudes, but "you should write code for humans first, computers second"). Rather than "semantic", "descriptive" seems to fit the bill.

"Abstract and descriptive". Doesn't quite roll off the tongue, but I tried :)
