What is the key difference between literature review and related work? I really can not find a justifiable answer to this question. Are they used interchangeably?
One answer that's i found to be true is that we use the term literature review in writing thesis and related work in the writing research paper. but i am not sure if it is correct or not?
I've been looking last week for the difference between the literature review and the background. And I found this which may help you, a good definition of what the literature supposed to be (in my opinion): https://academia.stackexchange.com/a/49629/57676

I'm not sure, but I think the literature review can be regarded as related work in more storytelling style. And yes, related work is more frequent in research papers because you don't have enough space to "build a conceptual structure that ties together all the key ideas". Therefore, you just describe briefly what has been done and maybe try to compare it theoretically against what you're proposing, I think.
