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.

For the AWS API documentation, see https://docs.aws.amazon.com/goto/WebAPI/textract-2018-06-27

METHODS

AnalyzeDocument

Document => Paws::Textract::Document
FeatureTypes => ArrayRef[Str|Undef]

Each argument is described in detail in: Paws::Textract::AnalyzeDocument

Returns: a Paws::Textract::AnalyzeDocumentResponse instance

Analyzes an input document for relationships between detected items.

The types of information returned are as follows:

  • Words and lines that are related to nearby lines and words. 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.

  • Selectable elements such as checkboxes and radio buttons. A SELECTION_ELEMENT Block object contains information about a selectable element.

  • Lines and words of text. A LINE Block object contains one or more WORD Block objects.

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.

For more information, see Document Text Analysis (https://docs.aws.amazon.com/textract/latest/dg/how-it-works-analyzing.html).

DetectDocumentText

Document => Paws::Textract::Document

Each argument is described in detail in: Paws::Textract::DetectDocumentText

Returns: a Paws::Textract::DetectDocumentTextResponse instance

Detects text in the input document. Amazon Textract can detect lines of text and the words that make up a line of text. The input document must be an image in JPG or PNG format. DetectDocumentText returns the detected text in 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.

DetectDocumentText is a synchronous operation. To analyze documents asynchronously, use StartDocumentTextDetection.

For more information, see Document Text Detection (https://docs.aws.amazon.com/textract/latest/dg/how-it-works-detecting.html).

GetDocumentAnalysis

JobId => Str
[MaxResults => Int]
[NextToken => Str]

Each argument is described in detail in: Paws::Textract::GetDocumentAnalysis

Returns: a Paws::Textract::GetDocumentAnalysisResponse instance

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:

  • Words and lines that are related to nearby lines and words. 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.

  • Selectable elements such as checkboxes and radio buttons. A SELECTION_ELEMENT Block object contains information about a selectable element.

  • Lines and words of text. A LINE Block object contains one or more WORD Block objects.

Use the MaxResults parameter to limit the number of blocks 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 (https://docs.aws.amazon.com/textract/latest/dg/how-it-works-analyzing.html).

GetDocumentTextDetection

JobId => Str
[MaxResults => Int]
[NextToken => Str]

Each argument is described in detail in: Paws::Textract::GetDocumentTextDetection

Returns: a Paws::Textract::GetDocumentTextDetectionResponse instance

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.

StartDocumentAnalysis

DocumentLocation => Paws::Textract::DocumentLocation
FeatureTypes => ArrayRef[Str|Undef]
[ClientRequestToken => Str]
[JobTag => Str]
[NotificationChannel => Paws::Textract::NotificationChannel]

Each argument is described in detail in: Paws::Textract::StartDocumentAnalysis

Returns: a Paws::Textract::StartDocumentAnalysisResponse instance

Starts asynchronous analysis of an input document for relationships between detected items such as key and value pairs, tables, and selection elements.

StartDocumentAnalysis can analyze text in documents that are in JPG, PNG, and PDF format. The documents are stored in an Amazon S3 bucket. Use DocumentLocation to specify the bucket name and file name of the document.

StartDocumentAnalysis returns a job identifier (JobId) that you use to get the results of the operation. When text analysis is finished, Amazon Textract publishes a completion status to the Amazon Simple Notification Service (Amazon SNS) topic that you specify in NotificationChannel. 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 GetDocumentAnalysis, and pass the job identifier (JobId) from the initial call to StartDocumentAnalysis.

For more information, see Document Text Analysis (https://docs.aws.amazon.com/textract/latest/dg/how-it-works-analyzing.html).

StartDocumentTextDetection

DocumentLocation => Paws::Textract::DocumentLocation
[ClientRequestToken => Str]
[JobTag => Str]
[NotificationChannel => Paws::Textract::NotificationChannel]

Each argument is described in detail in: Paws::Textract::StartDocumentTextDetection

Returns: a Paws::Textract::StartDocumentTextDetectionResponse instance

Starts the asynchronous detection of text in a document. Amazon Textract can detect lines of text and the words that make up a line of text.

StartDocumentTextDetection can analyze text in documents that are in JPG, PNG, and PDF format. The documents are stored in an Amazon S3 bucket. Use DocumentLocation to specify the bucket name and file name of the document.

StartTextDetection returns a job identifier (JobId) that you use to get the results of the operation.
