<p>Natural language processing is on topic here, as @amoeba points out. But I think it'd be a good idea to clarify the point of your question in its body. Do you want to know <em>how</em> to recognize named entities within HTML links (given the lack of usual orthographic or syntactic clues)? Asking what <a href="https://en.wikipedia.org/wiki/Named-entity_recognition" rel="nofollow">NER</a> typically involves is a bit wishy-washy - it's likely to depend on the application.</p>
