stanzaで言語分析 3

stanzaを使ってみる 3

---

以前の投稿でstanzaを使ってみたことをまとめた．

今回はその続きで依存構造解析（Dependency Parsing）をstanzaで行ってみたい．

コードは下記．

import stanza

stanza.download('en')
nlp = stanza.Pipeline('en')

text = "The quick brown fox jumps over the lazy dog."

doc = nlp(text)

for sentence in doc.sentences:
    print("Dependency Parse:")
    for word in sentence.words:
        print(f"{word.text} <--{word.deprel}-- {sentence.words[word.head - 1].text if word.head > 0 else 'ROOT'}")

Output例

Dependency Parse:

The <–det– fox

quick <–amod– fox

brown <–amod– fox

fox <–nsubj– jumps

jumps <–root– ROOT

over <–case– dog

the <–det– dog

lazy <–amod– dog

dog <–obl– jumps

. <–punct– jumps
