Main.Textract.analyze_documentMethod
analyze_document(document, feature_types)
analyze_document(document, feature_types, params::Dict{String,<:Any})

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 KEYVALUESET: 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 QUERYRESULT 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 SELECTIONELEMENT 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. For more information, see Document Text Analysis.

Arguments

  • document: The input document as base64-encoded bytes or an Amazon S3 object. If you use the AWS CLI to call Amazon Textract operations, you can't pass image bytes. The document must be an image in JPEG, PNG, PDF, or TIFF format. If you're using an AWS SDK to call Amazon Textract, you might not need to base64-encode image bytes that are passed using the Bytes field.
  • feature_types: A list of the types of analysis to perform. Add TABLES to the list to return information about the tables that are detected in the input document. Add FORMS to return detected form data. Add SIGNATURES to return the locations of detected signatures. To perform both forms and table analysis, add TABLES and FORMS to FeatureTypes. To detect signatures within form data and table data, add SIGNATURES to either TABLES or FORMS. All lines and words detected in the document are included in the response (including text that isn't related to the value of FeatureTypes).

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

  • "HumanLoopConfig": Sets the configuration for the human in the loop workflow for analyzing documents.
  • "QueriesConfig": Contains Queries and the alias for those Queries, as determined by the input.
Main.Textract.analyze_expenseMethod
analyze_expense(document)
analyze_expense(document, params::Dict{String,<:Any})

AnalyzeExpense synchronously analyzes an input document for financially related relationships between text. Information is returned as ExpenseDocuments and seperated as follows: 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.

Arguments

  • document:
Main.Textract.analyze_idMethod
analyze_id(document_pages)
analyze_id(document_pages, params::Dict{String,<:Any})

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.

Arguments

  • document_pages: The document being passed to AnalyzeID.
Main.Textract.detect_document_textMethod
detect_document_text(document)
detect_document_text(document, params::Dict{String,<:Any})

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 in one of the following image formats: JPEG, PNG, PDF, or TIFF. 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.

Arguments

  • document: The input document as base64-encoded bytes or an Amazon S3 object. If you use the AWS CLI to call Amazon Textract operations, you can't pass image bytes. The document must be an image in JPEG or PNG format. If you're using an AWS SDK to call Amazon Textract, you might not need to base64-encode image bytes that are passed using the Bytes field.
Main.Textract.get_document_analysisMethod
get_document_analysis(job_id)
get_document_analysis(job_id, params::Dict{String,<:Any})

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 KEYVALUESET: 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 QUERYRESULT 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. While processing a document with queries, look out for INVALIDREQUESTPARAMETERS 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 SELECTIONELEMENT 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.

Arguments

  • job_id: A unique identifier for the text-detection job. The JobId is returned from StartDocumentAnalysis. A JobId value is only valid for 7 days.
