分析實體

實體分析會檢查指定文字中出現的已知實體 (公眾人物或地標等專有名詞) 並傳回有關這些實體的資訊。實體分析是透過 analyzeEntities 方法執行。如要瞭解 Natural Language 識別的實體類型，請參閱實體說明文件。如需有關 Natural Language API 支援哪些語言的資訊，請參閱語言支援。

本節示範幾種偵測文件中實體的方法。請為每份文件分別提交要求。

分析字串中的實體

以下示範如何針對直接傳送至 Natural Language API 的文字字串執行實體分析：

通訊協定

POST 要求，並提供適當的要求主體，如同下列範例所示。documents:analyzeEntities

範例使用 gcloud auth application-default print-access-token 指令，取得透過 Google Cloud Platform gcloud CLI 建立的專案服務帳戶存取權杖。如需安裝 gcloud CLI、使用服務帳戶建立專案的操作說明，請參閱快速入門導覽課程。

curl -X POST \      -H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \      -H "Content-Type: application/json; charset=utf-8" \      --data "{   'encodingType': 'UTF8',   'document': {     'type': 'PLAIN_TEXT',     'content': 'President Trump will speak from the White House, located   at 1600 Pennsylvania Ave NW, Washington, DC, on October 7.'   } }" "https://language.googleapis.com/v2/documents:analyzeEntities"

如未指定 document.language_code，系統會自動偵測語言。如需有關 Natural Language API 支援哪些語言的資訊，請參閱語言支援。如需更多有關設定要求主體的資訊，請參閱 Document 參考說明文件。

如果要求成功，伺服器會傳回 200 OK HTTP 狀態碼與 JSON 格式的回應：

gcloud

如需完整的詳細資訊，請參閱 analyze-entities 指令。

如要執行實體分析，請使用 gcloud CLI，並使用 --content 標記標示待分析內容：

分析 Cloud Storage 內容中的實體

為方便起見，Natural Language API 可以直接對 Cloud Storage 中的檔案執行實體分析，您無需在要求內容中傳送檔案的內容。

以下示範如何對位於 Cloud Storage 的檔案執行實體分析。

通訊協定

POST 要求，並提供適當的要求主體及文件路徑，如同下列範例所示。POSTdocuments:analyzeEntities

curl -X POST \      -H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \      -H "Content-Type: application/json; charset=utf-8" \      --data "{   'document':{     'type':'PLAIN_TEXT',     'gcsContentUri':'gs://<bucket-name>/<object-name>'   } }" "https://language.googleapis.com/v2/documents:analyzeEntities"
