AWS SDK またはコマンドラインツールAnalyzeDocumentで を使用する

以下のコード例は、AnalyzeDocument の使用方法を示しています。



次の analyze-document の例は、ドキュメント内のテキストを分析する方法を示しています。


aws textract analyze-document \ --document '{"S3Object":{"Bucket":"bucket","Name":"document"}}' \ --feature-types '["TABLES","FORMS"]'

Windows :

aws textract analyze-document \ --document "{\"S3Object\":{\"Bucket\":\"bucket\",\"Name\":\"document\"}}" \ --feature-types "[\"TABLES\",\"FORMS\"]" \ --region region-name
