如何从给定的句子中删除关键字

Question

How can I remove a keyword from a phrase?

For example,

Lionel Andrés Messi is an Argentine professional footballer who plays as a forward and captains both Spanish club Barcelona and the Argentina national team.

How can I remove a keyword (except for the name of the person) from this sentence, such as "American", "footballer", "Barcelona" to name a few.

I have realised that the keyword must be a noun , and I came across a library called NLTK, and maybe that can help me what I want to achieve.

Function example:

remove(sentence, word_to_not_remove)

>>> sentence = 'Lionel Andrés Messi is an Argentine professional footballer who plays as a forward and captains both Spanish club Barcelona and the Argentina national team.'
>>> remove(sentence, 'Lionel Andrés Messi')
footballer

Answer 1

I think what you need here is NER(Named Entity Recognition).

As a starting step, you can Look at Spacy [ https://explosion.ai/demos/displacy-ent ]

import spacy
text = "Lionel Andrés Messi is an Argentine professional footballer who plays as a forward and captains both Spanish club Barcelona and the Argentina national team."
nlp = spacy.load("en_core_web_sm")
doc = nlp(text)

for ent in doc.ents:
    print(ent.text, ent.start_char, ent.end_char, ent.label_)

Andrés Messi 7 19 PERSON
Argentine 26 35 NORP
Spanish 101 108 NORP
Barcelona 114 123 GPE
Argentina 132 141 GPE

PS: If you need a specific Entity Extraction, you may have to train it for your specific use case
