实时分析输出

文本输入的输出

如果使用 Text 参数输入文本，输出将由分析检测到的实体数组组成。以下示例显示了检测到两个 JUDGE 实体的分析。

{
        "Entities":
        [
            {
                "BeginOffset": 0,
                "EndOffset": 22,
                "Score": 0.9763959646224976,
                "Text": "John Johnson",
                "Type": "JUDGE"
            },
            {
                "BeginOffset": 11,
                "EndOffset": 15,
                "Score": 0.9615424871444702,
                "Text": "Thomas Kincaid",
                "Type": "JUDGE"
            }
        ]
    }

半结构化输入的输出

对于半结构化输入文档或文本文件，输出可以包括以下附加字段：

• DocumentMetadata — 提取有关文档的信息。元数据包括文档中的页面列表，以及从每页中提取的字符数。如果请求包含 Byte 参数，则响应中会显示此字段。

• DocumentType -输入文档中每页的文档类型。此字段出现在包含该 Byte 参数的请求的响应中。

• 块：有关输入文档中每个文本块的信息。块是嵌套的。页面块包含每行文本的块，其中每个单词都包含一个块。此字段出现在包含该 Byte 参数的请求的响应中。

• BlockReferences — 对该实体的每个区块的引用。此字段出现在包含该 Byte 参数的请求的响应中。文本文件中不存在该字段。

• 错误：系统在处理输入文档时检测到的页面级错误。如果系统未遇到任何错误，则该字段为空。

有关这些输出字段的描述，请参阅DetectEntities《Amazon Comprehend API 参考》。有关布局元素的更多信息，请参阅《Amazon Textract 开发人员指南》中的 Amazon Textract 分析对象。

以下示例显示了单页扫描的 PDF 输入文档的输出。
