MLS-C01 · Question #356

A law firm handles thousands of contracts every day. Every contract must be signed. Currently, a lawyer manually checks all contracts for signatures. The law firm is developing a machine learning (ML)

The correct answer is C. Use the StartDocumentAnalysis API action to detect the signatures. Return the confidence scores. To automate signature detection in thousands of contracts daily and obtain a confidence score for each page using Amazon Textract, the StartDocumentAnalysis API action should be used to initiate an asynchronous analysis with the FeatureTypes parameter set to detect signatures.

Machine Learning Implementation and Operations

Question

A law firm handles thousands of contracts every day. Every contract must be signed. Currently, a lawyer manually checks all contracts for signatures. The law firm is developing a machine learning (ML) solution to automate signature detection for each contract. The ML solution must also provide a confidence score for each contract page. Which Amazon Textract API action can the law firm use to generate a confidence score for each page of each contract?

Options

  • AUse the AnalyzeDocument API action. Set the FeatureTypes parameter to SIGNATURES. Return
  • BUse the Prediction API call on the documents. Return the signatures and confidence scores for
  • CUse the StartDocumentAnalysis API action to detect the signatures. Return the confidence scores
  • DUse the GetDocumentAnalysis API action to detect the signatures. Return the confidence scores

Why each option

To automate signature detection in thousands of contracts daily and obtain a confidence score for each page using Amazon Textract, the StartDocumentAnalysis API action should be used to initiate an asynchronous analysis with the FeatureTypes parameter set to detect signatures.

AUse the AnalyzeDocument API action. Set the FeatureTypes parameter to SIGNATURES. Return

The AnalyzeDocument API action is synchronous, which would not be suitable for processing "thousands of contracts every day" due to potential rate limits and longer processing times.

BUse the Prediction API call on the documents. Return the signatures and confidence scores for

Amazon Textract does not have a "Prediction API" action; its primary APIs for document analysis are DetectDocumentText and AnalyzeDocument (and their asynchronous counterparts).

CUse the StartDocumentAnalysis API action to detect the signatures. Return the confidence scoresCorrect

The StartDocumentAnalysis API action initiates an asynchronous document analysis job, and when configured with the FeatureTypes parameter to detect SIGNATURES, it can process thousands of contracts daily and generate confidence scores for signature presence on each page.

DUse the GetDocumentAnalysis API action to detect the signatures. Return the confidence scores

The GetDocumentAnalysis API action is used to retrieve the results of a previously initiated StartDocumentAnalysis job; it does not initiate the detection or generate confidence scores itself.
