Class: AWS.Textract

Inherits:
AWS.Service show all
Identifier:
textract
API Version:
2018-06-27
Defined in:
(unknown)

Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

Amazon Textract detects and analyzes text in documents and converts it into machine-readable text. This is the API reference documentation for Amazon Textract.

Sending a Request Using Textract

var textract = new AWS.Textract();
textract.analyzeDocument(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the Textract object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var textract = new AWS.Textract({apiVersion: '2018-06-27'});

You can also set the API version globally in AWS.config.apiVersions using the textract service identifier:

AWS.config.apiVersions = {
  textract: '2018-06-27',
  // other service API versions
};

var textract = new AWS.Textract();

Method Details

analyzeDocument(params = {}, callback) ⇒ AWS.Request

Analyzes an input document for relationships between detected items.

The types of information returned are as follows:

  • Form data (key-value pairs). The related information is returned in two Block objects, each of type KEY_VALUE_SET: a KEY Block object and a VALUE Block object. For example, Name: Ana Silva Carolina contains a key and value. Name: is the key. Ana Silva Carolina is the value.

  • Table and table cell data. A TABLE Block object contains information about a detected table. A CELL Block object is returned for each cell in a table.

  • Lines and words of text. A LINE Block object contains one or more WORD Block objects. All lines and words that are detected in the document are returned (including text that doesn't have a relationship with the value of FeatureTypes).

  • Signatures. A SIGNATURE Block object contains the location information of a signature in a document. If used in conjunction with forms or tables, a signature can be given a Key-Value pairing or be detected in the cell of a table.

  • Query. A QUERY Block object contains the query text, alias and link to the associated Query results block object.

  • Query Result. A QUERY_RESULT Block object contains the answer to the query and an ID that connects it to the query asked. This Block also contains a confidence score.

Selection elements such as check boxes and option buttons (radio buttons) can be detected in form data and in tables. A SELECTION_ELEMENT Block object contains information about a selection element, including the selection status.

You can choose which type of analysis to perform by specifying the FeatureTypes list.

The output is returned in a list of Block objects.

AnalyzeDocument is a synchronous operation. To analyze documents asynchronously, use StartDocumentAnalysis.

  • LineItemGroups- A data set containing LineItems which store information about the lines of text, such as an item purchased and its price on a receipt.

  • SummaryFields- Contains all other information a receipt, such as header information or the vendors name.

Service Reference:

Examples:

Calling the analyzeExpense operation

var params = {
  Document: { /* required */
    Bytes: Buffer.from('...') || 'STRING_VALUE' /* Strings will be Base-64 encoded on your behalf */,
    S3Object: {
      Bucket: 'STRING_VALUE',
      Name: 'STRING_VALUE',
      Version: 'STRING_VALUE'
    }
  }
};
textract.analyzeExpense(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • Document — (map)

      The input document, either as bytes or as an S3 object.

      You pass image bytes to an Amazon Textract API operation by using the Bytes property. For example, you would use the Bytes property to pass a document loaded from a local file system. Image bytes passed by using the Bytes property must be base64 encoded. Your code might not need to encode document file bytes if you're using an AWS SDK to call Amazon Textract API operations.

      You pass images stored in an S3 bucket to an Amazon Textract API operation by using the S3Object property. Documents stored in an S3 bucket don't need to be base64 encoded.

      The AWS Region for the S3 bucket that contains the S3 object must match the AWS Region that you use for Amazon Textract operations.

      If you use the AWS CLI to call Amazon Textract operations, passing image bytes using the Bytes property isn't supported. You must first upload the document to an Amazon S3 bucket, and then call the operation using the S3Object property.

      For Amazon Textract to process an S3 object, the user must have permission to access the S3 object.

      • Bytes — (Buffer, Typed Array, Blob, String)

        A blob of base64-encoded document bytes. The maximum size of a document that's provided in a blob of bytes is 5 MB. The document bytes must be in PNG or JPEG format.

        If you're using an AWS SDK to call Amazon Textract, you might not need to base64-encode image bytes passed using the Bytes field.

      • S3Object — (map)

        Identifies an S3 object as the document source. The maximum size of a document that's stored in an S3 bucket is 5 MB.

        • Bucket — (String)

          The name of the S3 bucket. Note that the # character is not valid in the file name.

        • Name — (String)

          The file name of the input document. Synchronous operations can use image files that are in JPEG or PNG format. Asynchronous operations also support PDF and TIFF format files.

        • Version — (String)

          If the bucket has versioning enabled, you can specify the object version.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

analyzeID(params = {}, callback) ⇒ AWS.Request

Analyzes identity documents for relevant information. This information is extracted and returned as IdentityDocumentFields, which records both the normalized field and value of the extracted text. Unlike other Amazon Textract operations, AnalyzeID doesn't return any Geometry data.

Service Reference:

Examples:

Calling the analyzeID operation

var params = {
  DocumentPages: [ /* required */
    {
      Bytes: Buffer.from('...') || 'STRING_VALUE' /* Strings will be Base-64 encoded on your behalf */,
      S3Object: {
        Bucket: 'STRING_VALUE',
        Name: 'STRING_VALUE',
        Version: 'STRING_VALUE'
      }
    },
    /* more items */
  ]
};
textract.analyzeID(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

    • AdapterId — (String)

      A string containing a unique ID for the adapter that will receive a new version.

    • ClientRequestToken — (String)

      Idempotent token is used to recognize the request. If the same token is used with multiple CreateAdapterVersion requests, the same session is returned. This token is employed to avoid unintentionally creating the same session multiple times.

      If a token is not provided, the SDK will use a version 4 UUID.
    • DatasetConfig — (map)

      Specifies a dataset used to train a new adapter version. Takes a ManifestS3Object as the value.

      • ManifestS3Object — (map)

        The S3 bucket name and file name that identifies the document.

        The AWS Region for the S3 bucket that contains the document must match the Region that you use for Amazon Textract operations.

        For Amazon Textract to process a file in an S3 bucket, the user must have permission to access the S3 bucket and file.

        • Bucket — (String)

          The name of the S3 bucket. Note that the # character is not valid in the file name.

        • Name — (String)

          The file name of the input document. Synchronous operations can use image files that are in JPEG or PNG format. Asynchronous operations also support PDF and TIFF format files.

        • Version — (String)

          If the bucket has versioning enabled, you can specify the object version.

    • KMSKeyId — (String)

      The identifier for your AWS Key Management Service key (AWS KMS key). Used to encrypt your documents.

    • OutputConfig — (map)

      Sets whether or not your output will go to a user created bucket. Used to set the name of the bucket, and the prefix on the output file.

      OutputConfig is an optional parameter which lets you adjust where your output will be placed. By default, Amazon Textract will store the results internally and can only be accessed by the Get API operations. With OutputConfig enabled, you can set the name of the bucket the output will be sent to the file prefix of the results where you can download your results. Additionally, you can set the KMSKeyID parameter to a customer master key (CMK) to encrypt your output. Without this parameter set Amazon Textract will encrypt server-side using the AWS managed CMK for Amazon S3.

      Decryption of Customer Content is necessary for processing of the documents by Amazon Textract. If your account is opted out under an AI services opt out policy then all unencrypted Customer Content is immediately and permanently deleted after the Customer Content has been processed by the service. No copy of of the output is retained by Amazon Textract. For information about how to opt out, see Managing AI services opt-out policy.

      For more information on data privacy, see the Data Privacy FAQ.

getDocumentAnalysis(params = {}, callback) ⇒ AWS.Request

Gets the results for an Amazon Textract asynchronous operation that analyzes text in a document.

You start asynchronous text analysis by calling StartDocumentAnalysis, which returns a job identifier (JobId). When the text analysis operation finishes, Amazon Textract publishes a completion status to the Amazon Simple Notification Service (Amazon SNS) topic that's registered in the initial call to StartDocumentAnalysis. To get the results of the text-detection operation, first check that the status value published to the Amazon SNS topic is SUCCEEDED. If so, call GetDocumentAnalysis, and pass the job identifier (JobId) from the initial call to StartDocumentAnalysis.

GetDocumentAnalysis returns an array of Block objects. The following types of information are returned:

  • Form data (key-value pairs). The related information is returned in two Block objects, each of type KEY_VALUE_SET: a KEY Block object and a VALUE Block object. For example, Name: Ana Silva Carolina contains a key and value. Name: is the key. Ana Silva Carolina is the value.

  • Table and table cell data. A TABLE Block object contains information about a detected table. A CELL Block object is returned for each cell in a table.

  • Lines and words of text. A LINE Block object contains one or more WORD Block objects. All lines and words that are detected in the document are returned (including text that doesn't have a relationship with the value of the StartDocumentAnalysis FeatureTypes input parameter).

  • Query. A QUERY Block object contains the query text, alias and link to the associated Query results block object.

  • Query Results. A QUERY_RESULT Block object contains the answer to the query and an ID that connects it to the query asked. This Block also contains a confidence score.

Note: While processing a document with queries, look out for INVALID_REQUEST_PARAMETERS output. This indicates that either the per page query limit has been exceeded or that the operation is trying to query a page in the document which doesn’t exist.

Selection elements such as check boxes and option buttons (radio buttons) can be detected in form data and in tables. A SELECTION_ELEMENT Block object contains information about a selection element, including the selection status.

Use the MaxResults parameter to limit the number of blocks that are returned. If there are more results than specified in MaxResults, the value of NextToken in the operation response contains a pagination token for getting the next set of results. To get the next page of results, call GetDocumentAnalysis, and populate the NextToken request parameter with the token value that's returned from the previous call to GetDocumentAnalysis.

For more information, see Document Text Analysis.

Service Reference:

Examples:

Calling the getDocumentAnalysis operation

var params = {
  JobId: 'STRING_VALUE', /* required */

getDocumentTextDetection(params = {}, callback) ⇒ AWS.Request

Gets the results for an Amazon Textract asynchronous operation that detects text in a document. Amazon Textract can detect lines of text and the words that make up a line of text.

You start asynchronous text detection by calling StartDocumentTextDetection, which returns a job identifier (JobId). When the text detection operation finishes, Amazon Textract publishes a completion status to the Amazon Simple Notification Service (Amazon SNS) topic that's registered in the initial call to StartDocumentTextDetection. To get the results of the text-detection operation, first check that the status value published to the Amazon SNS topic is SUCCEEDED. If so, call GetDocumentTextDetection, and pass the job identifier (JobId) from the initial call to StartDocumentTextDetection.

GetDocumentTextDetection returns an array of Block objects.

Each document page has as an associated Block of type PAGE. Each PAGE Block object is the parent of LINE Block objects that represent the lines of detected text on a page. A LINE Block object is a parent for each word that makes up the line. Words are represented by Block objects of type WORD.

Use the MaxResults parameter to limit the number of blocks that are returned. If there are more results than specified in MaxResults, the value of NextToken in the operation response contains a pagination token for getting the next set of results. To get the next page of results, call GetDocumentTextDetection, and populate the NextToken request parameter with the token value that's returned from the previous call to GetDocumentTextDetection.

For more information, see Document Text Detection.

Service Reference:

Examples:

Calling the getDocumentTextDetection operation

var params = {

getExpenseAnalysis(params = {}, callback) ⇒ AWS.Request

Gets the results for an Amazon Textract asynchronous operation that analyzes invoices and receipts. Amazon Textract finds contact information, items purchased, and vendor name, from input invoices and receipts.

You start asynchronous invoice/receipt analysis by calling StartExpenseAnalysis, which returns a job identifier (JobId). Upon completion of the invoice/receipt analysis, Amazon Textract publishes the completion status to the Amazon Simple Notification Service (Amazon SNS) topic. This topic must be registered in the initial call to StartExpenseAnalysis. To get the results of the invoice/receipt analysis operation, first ensure that the status value published to the Amazon SNS topic is SUCCEEDED. If so, call GetExpenseAnalysis, and pass the job identifier (JobId) from the initial call to StartExpenseAnalysis.

Use the MaxResults parameter to limit the number of blocks that are returned. If there are more results than specified in MaxResults, the value of NextToken in the operation response contains a pagination token for getting the next set of results. To get the next page of results, call GetExpenseAnalysis, and populate the NextToken request parameter with the token value that's returned from the previous call to GetExpenseAnalysis.

For more information, see Analyzing Invoices and Receipts.

getLendingAnalysis(params = {}, callback) ⇒ AWS.Request

Gets the results for an Amazon Textract asynchronous operation that analyzes text in a lending document.

You start asynchronous text analysis by calling StartLendingAnalysis, which returns a job identifier (JobId). When the text analysis operation finishes, Amazon Textract publishes a completion status to the Amazon Simple Notification Service (Amazon SNS) topic that's registered in the initial call to StartLendingAnalysis.

To get the results of the text analysis operation, first check that the status value published to the Amazon SNS topic is SUCCEEDED. If so, call GetLendingAnalysis, and pass the job identifier (JobId) from the initial call to StartLendingAnalysis.

Service Reference:

Examples:

Calling the getLendingAnalysis operation

var params = {
  JobId: 'STRING_VALUE', /* required */
  MaxResults: 'NUMBER_VALUE',
  NextToken: 'STRING_VALUE'
};
textract.getLendingAnalysis(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • JobId — (String)

      A unique identifier for the lending or text-detection job. The JobId is returned from StartLendingAnalysis. A JobId value is only valid for 7 days.

    • MaxResults — (Integer)

    • NextToken — (String)

      If the previous response was incomplete, Amazon Textract returns a pagination token in the response. You can use this pagination token to retrieve the next set of lending results.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

getLendingAnalysisSummary(params = {}, callback) ⇒ AWS.Request

Gets summarized results for the StartLendingAnalysis operation, which analyzes text in a lending document. The returned summary consists of information about documents grouped together by a common document type. Information like detected signatures, page numbers, and split documents is returned with respect to the type of grouped document.

You start asynchronous text analysis by calling StartLendingAnalysis, which returns a job identifier (JobId). When the text analysis operation finishes, Amazon Textract publishes a completion status to the Amazon Simple Notification Service (Amazon SNS) topic that's registered in the initial call to StartLendingAnalysis.

To get the results of the text analysis operation, first check that the status value published to the Amazon SNS topic is SUCCEEDED. If so, call GetLendingAnalysisSummary, and pass the job identifier (JobId) from the initial call to StartLendingAnalysis.

Service Reference:

Examples:

Calling the getLendingAnalysisSummary operation

var params = {
  JobId: 'STRING_VALUE' /* required */
};
textract.getLendingAnalysisSummary(params, function(err, data) {

      The idempotent token that you use to identify the start request. If you use the same token with multiple StartLendingAnalysis requests, the same JobId is returned. Use ClientRequestToken to prevent the same job from being accidentally started more than once. For more information, see Calling Amazon Textract Asynchronous Operations.

    • JobTag — (String)

      An identifier that you specify to be included in the completion notification published to the Amazon SNS topic. For example, you can use JobTag to identify the type of document that the completion notification corresponds to (such as a tax form or a receipt).

    • NotificationChannel — (map)

      The Amazon Simple Notification Service (Amazon SNS) topic to which Amazon Textract publishes the completion status of an asynchronous document operation.

      • SNSTopicArnrequired — (String)

        The Amazon SNS topic that Amazon Textract posts the completion status to.

      • RoleArnrequired — (String)

        The Amazon Resource Name (ARN) of an IAM role that gives Amazon Textract publishing permissions to the Amazon SNS topic.

    • OutputConfig — (map)

      Sets whether or not your output will go to a user created bucket. Used to set the name of the bucket, and the prefix on the output file.

      OutputConfig is an optional parameter which lets you adjust where your output will be placed. By default, Amazon Textract will store the results internally and can only be accessed by the Get API operations. With OutputConfig enabled, you can set the name of the bucket the output will be sent to the file prefix of the results where you can download your results. Additionally, you can set the KMSKeyID parameter to a customer master key (CMK) to encrypt your output. Without this parameter set Amazon Textract will encrypt server-side using the AWS managed CMK for Amazon S3.

      Decryption of Customer Content is necessary for processing of the documents by Amazon Textract. If your account is opted out under an AI services opt out policy then all unencrypted Customer Content is immediately and permanently deleted after the Customer Content has been processed by the service. No copy of of the output is retained by Amazon Textract. For information about how to opt out, see Managing AI services opt-out policy.

      For more information on data privacy, see the Data Privacy FAQ.

      • S3Bucketrequired — (String)

        The name of the bucket your output will go to.

      • S3Prefix — (String)

        The prefix of the object key that the output will be saved to. When not enabled, the prefix will be “textract_output".

    • KMSKeyId — (String)

      The KMS key used to encrypt the inference results. This can be in either Key ID or Key Alias format. When a KMS key is provided, the KMS key will be used for server-side encryption of the objects in the customer bucket. When this parameter is not enabled, the result will be encrypted server side, using SSE-S3.
