擷取關鍵詞組

已完成

關鍵片語擷取是評估文件的文字過程，然後識別文件上下文中的主要內容。

關鍵片語擷取最適合用於較大的檔（可分析的大小上限為5,120個字元）。

如同語言偵測，REST 介面可讓您提交一或多個文件進行分析。

    "kind": "KeyPhraseExtraction",
    "parameters": {
        "modelVersion": "latest"
    },
    "analysisInput":{
        "documents":[
            {
              "id": "1",
              "language": "en",
              "text": "You must be the change you wish 
                       to see in the world."
            },
            {
              "id": "2",
              "language": "en",
              "text": "The journey of a thousand miles 
                       begins with a single step."
            }
        ]
    }
}
