我创建了一个用Spacy标记所有命名实体的函数:
def tag_ne(content):
doc = nlp(content)
text = doc.text
for ent in doc.ents:
text = re.sub(ent.text, ent.label_, text)
return text
当我将它应用于小型Pandas系列的unicode字符串时,它可以工作。但是,当我将它应用到我的整个数据集时,我收到一个错误(因为特定观察引起的错误)。我无法知道导致错误的原因,我无法共享我的数据集,但错误如下:
---------------------------------------------------------------------------

241 except error, v:
--> 242 raise error, v # invalid expression
243 if len(_cache) >= _MAXCACHE:

我可以使用哪种替代方法标记可能让我解决此错误的所有命名实体?否则,我该如何解决?
答案 0 :(得分:0)
当然,您可以知道导致错误的行。只需添加一个try / except语句:
def tag_ne(content):
doc = nlp(content)
text = doc.text
for ent in doc.ents:
try:
text = re.sub(ent.text, ent.label_, text)
except Exception as e:
print(ent.text, ent.label_, '\n', e)
return text
