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?

Use the AnalyzeDocument API action. Set the FeatureTypes parameter to SIGNATURES. Return the confidence scores for each page.

Use the Prediction API call on the documents. Return the signatures and confidence scores for each page.

Use the StartDocumentAnalysis API action to detect the signatures. Return the confidence scores for each page.

Use the GetDocumentAnalysis API action to detect the signatures. Return the confidence scores for each page.

Explanations:

TheAnalyzeDocumentAPI withFeatureTypesset toSIGNATUREScan detect signatures and provide confidence scores.

There is noPredictionAPI in Amazon Textract; thus, this option does not apply to signature detection tasks.

StartDocumentAnalysisis used for asynchronous processing but does not directly return confidence scores for each page.

GetDocumentAnalysisretrieves results from an asynchronous job but does not perform analysis directly for confidence scoring.

    My best guess is:
    Use the AnalyzeDocument API action. Set the FeatureTypes parameter to SIGNATURES. Return the confidence scores for each page.
