关系提取

运行状况文本分析功能关系提取，用于标识文本中提到的概念或实体之间有意义的连接。 例如，通过将疾病名称与时间关联来查找“疾病时间”关系。 另一个例子是“药物剂量”关系，该关系通过将提取的药物与其所提取剂量联系起来而发现。 以下示例演示 JSON 输出中如何表示关系。

关系提取输出包含关系类型的实体的 URI 引用和分配的角色。 例如，在下面的 JSON 中：

"relations": [
    {
        "relationType": "DosageOfMedication",
        "entities": [
            {
                "ref": "#/results/documents/0/entities/0",
                "role": "Dosage"
            },
            {
                "ref": "#/results/documents/0/entities/1",
                "role": "Medication"
            }
        ]
    },
    {
        "relationType": "RouteOfMedication",
        "entities": [
            {
                "ref": "#/results/documents/0/entities/1",
                "role": "Medication"
            },
            {
                "ref": "#/results/documents/0/entities/2",
                "role": "Route"
            }
        ]
    }
]
