给出一段python实现实体链接额代码示例
时间: 2023-06-09 18:01:56 浏览: 58
这是一个简单的Python实例,用于将文本中的实体链接到相关的实体页面:
```python
import requests
import json
# Entity Linking API endpoint
api_endpoint = "http://api.dbpedia-spotlight.org/en/annotate"
# Text to annotate
text = "Barack Obama was born in Hawaii."
# Set HTTP headers
headers = {
"Accept": "application/json"
}
# Set request parameters
params = {
"text": text,
"confidence": 0.5,
"support": 20
}
# Send HTTP request
response = requests.get(api_endpoint, params=params, headers=headers)
# Parse JSON response
json_response = json.loads(response.text)
# Iterate over annotations
for annotation in json_response["Resources"]:
# Get URI of annotated entity
uri = annotation["@URI"]
# Get surface form of annotated entity
surface_form = annotation["@surfaceForm"]
# Replace surface form with entity URI
text = text.replace(surface_form, uri)
# Print annotated text
print(text)
```
请注意,此示例需要访问Entity Linking API,并使用适当的凭据进行身份验证。此外,实体链接的结果可能因输入文本和相关信息而异。
