get_lending_analysis#
- Textract.Client.get_lending_analysis(**kwargs)#
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 toStartLendingAnalysis.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 toStartLendingAnalysis.See also: AWS API Documentation
Request Syntax
response = client.get_lending_analysis( JobId='string', MaxResults=123, NextToken='string' )
- Parameters:
JobId (string) –
[REQUIRED]
A unique identifier for the lending or text-detection job. The
JobIdis returned fromStartLendingAnalysis. AJobIdvalue is only valid for 7 days.MaxResults (integer) – The maximum number of results to return per paginated call. The largest value that you can specify is 30. If you specify a value greater than 30, a maximum of 30 results is returned. The default value is 30.
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.

(dict) –
A
Blockrepresents items that are recognized in a document within a group of pixels close to each other. The information returned in aBlockobject 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
Blockobjects is returned by both synchronous and asynchronous operations. In synchronous operations, such as DetectDocumentText, the array ofBlockobjects 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:
PAGE - Contains a list of the LINE
Blockobjects that are detected on a document page.WORD - A word detected on a document page. A word is one or more ISO basic Latin script characters that aren’t separated by spaces.
LINE - A string of tab-delimited, contiguous words that are detected on a document page.
In text analysis operations, the following types are returned:
PAGE - Contains a list of child
Blockobjects that are detected on a document page.KEY_VALUE_SET - Stores the KEY and VALUE
Blockobjects for linked text that’s detected on a document page. Use theEntityTypefield to determine if a KEY_VALUE_SET object is a KEYBlockobject or a VALUEBlockobject.WORD - A word that’s detected on a document page. A word is one or more ISO basic Latin script characters that aren’t separated by spaces.
LINE - A string of tab-delimited, contiguous words that are detected on a document page.
TABLE - A table that’s detected on a document page. A table is grid-based information with two or more rows or columns, with a cell span of one row and one column each.
TABLE_TITLE - The title of a table. A title is typically a line of text above or below a table, or embedded as the first row of a table.
TABLE_FOOTER - The footer associated with a table. A footer is typically a line or lines of text below a table or embedded as the last row of a table.
CELL - A cell within a detected table. The cell is the parent of the block that contains the text in the cell.
MERGED_CELL - A cell in a table whose content spans more than one row or column. The
Relationshipsarray for this cell contain data from individual cells.SELECTION_ELEMENT - A selection element such as an option button (radio button) or a check box that’s detected on a document page. Use the value of
SelectionStatusto determine the status of the selection element.SIGNATURE - The location and confidence score of a signature detected on a document page. Can be returned as part of a Key-Value pair or a detected cell.
QUERY - A question asked during the call of AnalyzeDocument. Contains an alias and an ID that attaches it to its answer.
QUERY_RESULT - A response to a question asked during the call of analyze document. Comes with an alias and ID for ease of locating in a response. Also contains location and confidence score.

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
Blockobjects is returned by both synchronous and asynchronous operations. In synchronous operations, such as DetectDocumentText, the array ofBlockobjects 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.
