上次我们简单介绍了Spacy,了解了它的安装及一些基础功能,如实体识别等。今天我们将进一步探讨Spacy的其他高级功能,包括词性还原、词性标注、名词块识别和依存分析等。
接下来,让我们直接进入代码部分:
```python import encoreweb_sm
parser = encoreweb_sm.load()
sentences = "There is an art, it says, or rather, a knack to flying." "The knack lies in learning how to throw yourself at the ground and miss." "In the beginning the Universe was created." "This has made a lot of people very angry and been widely regarded as a bad move."
print("解析文本中的句子:") sents = [sent for sent in parser(sentences).sents] for sentence in sents: print(sentence)
print("n分词结果:") tokens = [token for token in sents[0] if len(token) > 1] print(tokens)
print("n词性还原结果:") lemmatokens = [token.lemma for token in sents[0] if len(token) > 1] print(lemma_tokens)
print("n简化版词性标注:") postokens = [token.pos for token in sents[0] if len(token) > 1] print(pos_tokens)
print("n详细版词性标注:") tagtokens = [token.tag for token in sents[0] if len(token) > 1] print(tag_tokens)
print("n依存关系分析:") deptokens = [token.dep for token in sents[0] if len(token) > 1] print(dep_tokens)
print("n名词块分析:") doc = parser(u"Autonomous cars shift insurance liability toward manufacturers") chunktext = [chunk.text for chunk in doc.nounchunks] print(chunk_text)
print("n名词块根节点的文本:") chunkroottext = [chunk.root.text for chunk in doc.nounchunks] print(chunkroot_text)
print("n名词块根节点的依存关系:") chunkrootdep_ = [chunk.root.dep_ for chunk in doc.nounchunks] print(chunkrootdep)
print("n名词块根节点的父节点文本:") chunkrootheadtext = [chunk.root.head.text for chunk in doc.nounchunks] print(chunkroothead_text) ```
最后,为大家提供一份关于句法依存分析的参考资料,这份资料来自斯坦福大学的自然语言处理项目,提供了详细的依存句法分析解释文档。
