Add Sentence pointer in Named Entity object

The named entities returned from .ents have individual spans returned. Is it possible to add a member to the span so that it points to the sentence that it is a part of?

Would breaking a document up into sentences first be a better way to go to keep entities and sentences self-contained?

Hmm. That’s probably a good idea.

In the meantime something like this should work:

    def get_sent(span):
        root = span.root
        i = 0
        while root.head is not root:
            root = root.head
            i += 1
            if i > len(root.doc):
                raise ValueError("Infinite loop. Cycle in parse tree?")
        return root.doc[root.left_edge.i : root.right_edge.i + 1]
