What is the terminology for "floating links"?

Quite often I come across this type of an answer:

The answer is in this mechanism. [2 lines of mechanism] Your mistake was [2 lines] 

https://link.to.com/a_research_paper

Also note that another reason is [2 lines]

The pattern here is that the user writes an answer, and in the middle of it, leaves a "floating link" - whose connection with either paragraph is unclear and requires some explanation.

It is not clear whether it's supposed to be a "Read more here" link, or a "Source from" link, or a "The full answer is here" link, or any other application the viewer could think of. A better way to write that link would have [How is this url supposed to help the reader?](url) (assuming markdown, but you get the point) Without the latter, this hurts user experience.

Far too often, I've found myself calling these "floating links", but I am not sure if this is the correct terminology. What is the correct terminology to refer to such links?
