def extract_spacy(self, text):
        try:
            doc = self.spacy(text)
            for ent in doc.ents:
                type_ = SPACY_TYPES.get(ent.label_)
                label = ent.text.strip()
                if type_ is not None and len(label):
                    entity = ExtractedEntity()

                    yield entity
        except Exception:
