My approach to avoid this is always to try and find a recent and well written Masters or Ph.D thesis in the area. You can't always find them of course, but if you do they tend to have pretty good context and a more detailed bibliography than you'll find elsewhere.

That said, if you are still at the point of inventing new terms for things people have been doing for decades, you are probably being fairly superficial in the area as well.

Research areas like CNN are especially prone to this because it is so much easier to apply the techniques than to understand the problem domain, and it generates a lot of low quality research papers. See also "when all you have is a hammer".
