理解：Detect_pii_entities 和 contains_pii_entities 之间的区别 boto3 comprehend

Question

我试图了解使用 boto3 comprehend 的 detector_pii_entities 和 contains_pii_entities 函数之间的区别。我尝试使用以下代码片段：

str_text = """
Hello Zhang Wei, I am John. Your AnyCompany Financial Services, LLC credit card account 1111-0000-1111-0008 has a minimum payment of $24.53 that is due by July 31st. Based on your autopay settings, we will withdraw your payment on the due date from your bank account number XXXXXX1111 with the routing number XXXXX0000.

"""

client = boto3.client('comprehend')
detect_pii = client.detect_pii_entities(
             Text=str_text,
             LanguageCode='en'
         )
print("detect pii: ", detect_pii)
contains_pii = client.detect_pii_entities(
             Text=str_text,
             LanguageCode='en'
         )
print("contains pii: ", contains_pii)

我得到的输出是：

detect_pii:  {'Entities': [{'Score': 0.9996908903121948, 'Type': 'NAME', 'BeginOffset': 52, 'EndOffset': 61}, {'Score': 0.9999550580978394, 'Type': 'NAME', 'BeginOffset': 68, 'EndOffset': 72}, {'Score': 0.9627901911735535, 'Type': 'CREDIT_DEBIT_NUMBER', 'BeginOffset': 134, 'EndOffset': 153}, {'Score': 0.9714980125427246, 'Type': 'DATE_TIME', 'BeginOffset': 201, 'EndOffset': 210}, {'Score': 0.9999960660934448, 'Type': 'BANK_ACCOUNT_NUMBER', 'BeginOffset': 320, 'EndOffset': 330}, {'Score': 0.999988317489624, 'Type': 'BANK_ROUTING', 'BeginOffset': 355, 'EndOffset': 364}, {'Score': 0.9999522566795349, 'Type': 'ADDRESS', 'BeginOffset': 406, 'EndOffset': 441}, {'Score': 0.9999591112136841, 'Type': 'PHONE', 'BeginOffset': 525, 'EndOffset': 537}, {'Score': 0.999980092048645, 'Type': 'PHONE', 'BeginOffset': 633, 'EndOffset': 645}, {'Score': 0.9995272159576416, 'Type': 'EMAIL', 'BeginOffset': 658, 'EndOffset': 680}], 'ResponseMetadata': {'RequestId': '80d513d3-83b3-4ebc-915a-1e2c731d1eb4', 'HTTPStatusCode': 200, 'HTTPHeaders': {'x-amzn-requestid': '80d513d3-83b3-4ebc-915a-1e2c731d1eb4', 'content-type': 'application/x-amz-json-1.1', 'content-length': '827', 'date': 'Fri, 04 Mar 2022 16:03:42 GMT'}, 'RetryAttempts': 0}}

contains_pii: {'Labels': [{'Name': 'DATE_TIME', 'Score': 0.9986850023269653}, {'Name': 'EMAIL', 'Score': 0.9985549449920654}, {'Name': 'BANK_ACCOUNT_NUMBER', 'Score': 0.8221991658210754}, {'Name': 'BANK_ROUTING', 'Score': 0.6654205918312073}, {'Name': 'CREDIT_DEBIT_NUMBER', 'Score': 1.0}, {'Name': 'PHONE', 'Score': 1.0}], 'ResponseMetadata': {'RequestId': 'f0361d1a-afad-4b4f-9877-fdbb5c297936', 'HTTPStatusCode': 200, 'HTTPHeaders': {'x-amzn-requestid': 'f0361d1a-afad-4b4f-9877-fdbb5c297936', 'content-type': 'application/x-amz-json-1.1', 'content-length': '285', 'date': 'Fri, 04 Mar 2022 16:03:42 GMT'}, 'RetryAttempts': 0}}

我发现在第二种情况下，名称和地址丢失，可能还缺少一些 PII 标签。我如何使用 contains. 文档建议名称和地址应可用以及控制台上的 Comprehend API 可以返回所有 PII 标签。

AWS 控制台：

{
    "Labels": [
        {
            "Name": "EMAIL",
            "Score": 1
        },
        {
            "Name": "DATE_TIME",
            "Score": 1
        },
        {
            "Name": "NAME",
            "Score": 0.8311530351638794
        },
        {
            "Name": "BANK_ROUTING",
            "Score": 0.7879412174224854
        },
        {
            "Name": "ADDRESS",
            "Score": 0.6723417043685913
        },
        {
            "Name": "BANK_ACCOUNT_NUMBER",
            "Score": 0.6297846436500549
        },
        {
            "Name": "CREDIT_DEBIT_NUMBER",
            "Score": 1
        },
        {
            "Name": "PHONE",
            "Score": 1
        }
    ]
}

不确定使用 boto3 包时缺少什么。使用的 boto3 版本：1.18.12
