我似乎 NLU 没有识别出我提供的全部数据。我是在代码中做错了什么，还是对 api 的工作方式有错误的假设？包含来自 api 的响应，其中包含分析的代码以及提交的完整文本。有一个增量，我不确定为什么会这样。
这是我的代码：
def nlu(text):
print("Calling NLU")
url = "https://gateway.watsonplatform.net/natural-language-understanding/api/v1/analyze?version=2017-02-27"
data = {
'text': text,
'language': "en",
'return_analyzed_text': True,
'clean': True,
'features': {
'entities': {
'emotion': True,
'sentiment': True,
'limit': 2
},
"concepts": {
"limit": 15
},
'keywords': {
'emotion': True,
'sentiment': True,
'limit': 2
}
}
}
headers = {
'content-type': "application/json"
}
username = os.getenv("nlu-username")
password = os.getenv("nlu-password")
print("NLU", username, password)
print("data", json.dumps(data))
response = requests.request("POST", url, data=json.dumps(data), headers=headers, auth=(username, password))
print("Done calling NLU")
print(response.text)
这是请求/响应：

D. the great city of TOT Makana Mexico bustled with thousands of people researchers examined the isotope ratios and skeletons to the now which held details of their diets when they were young they found evidence for significant migration into the city a majority of the individuals were born elsewhere with further geological and skeletal analysis they may be able to map where those people came from that work in tier two Akon is also an example of how bio anthropologists study skeletons in cemeteries and mass graves and analyze their similarities and differences from not information they can learn about cultural beliefs social norms wars and what caused their deaths today we use these tools to answer big questions about how forces like migration and disease shape the modern world DNA analysis is even possible in some relatively well preserved ancient remains that's helping us understand how diseases like tuberculosis have evolved over the centuries so we can build better treatments for people today ocean skeletons can tell us a surprisingly great deal about the past two of your remains are someday buried intact what might archaeologists of the distant future learn from them"
