List of the targeted feature types for the requested adapter version.
(string) --
Status (string) --
The status of the adapter version that has been requested.
StatusMessage (string) --
A message that describes the status of the requested adapter version.
DatasetConfig (dict) --
Specifies a dataset used to train a new adapter version. Takes a ManifestS3Objec as the value.
ManifestS3Object (dict) --
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 (dict) --
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 .

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 .

Response Structure
(dict) --
DocumentMetadata (dict) --
Metadata about the analyzed document. An example is the number of pages.
Pages (integer) --
The number of pages that are detected in the document.
Blocks (list) --
The items that are detected and analyzed by AnalyzeDocument .
(dict) --
A Block represents items that are recognized in a document within a group of pixels close to each other. The information returned in a Block object depends on the type of operation. In text detection for documents (for example DetectDocumentText ), you get information about the detected words and lines of text. In text analysis (for example AnalyzeDocument ), you can also get information about the fields, tables, and selection elements that are detected in the document.
An array of Block objects is returned by both synchronous and asynchronous operations. In synchronous operations, such as DetectDocumentText , the array of Block objects is the entire set of results. In asynchronous operations, such as GetDocumentAnalysis , the array is returned over one or more responses.
For more information, see How Amazon Textract Works .
BlockType (string) --
The type of text item that's recognized. In operations for text detection, the following types are returned:

Starts the asynchronous analysis of an input document for relationships between detected items such as key-value pairs, tables, and selection elements.
StartDocumentAnalysis can analyze text in documents that are in JPEG, PNG, TIFF, 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 .
