Q: What is Amazon Textract?
A: Amazon Textract is a document analysis service that detects and extracts text, structured data, such as fields of interest and their values, and tables from images and scans of documents. Amazon Textract's machine learning models have been trained on millions of documents so that virtually any document type you upload is automatically recognized and processed for text extraction. When information is extracted from documents, the service returns a confidence score for each element it identifies so that you can make informed decisions about how you want to use the results. For instance, if you are extracting information from tax documents you can set custom rules to flag any extracted information with a confidence score lower than 95%. Also, all extracted data are returned with bounding box coordinates, which is a rectangular frame that fully encompasses each piece of data identified, so that you can quickly identify where a word or number appears on a document. You can access these features with the Amazon Textract API, in the AWS Management Console, or using the AWS command-line interface (CLI).
Q: What are the most common use cases for Amazon Textract?
A: The most common use cases for Amazon Textract include:
- Import Documents and Forms into Business Applications
- Create Smart Search Indexes
- Build Automated Document Processing Workflows
- Maintain Compliance in Document Archives
- Extract Text for Natural Language Processing (NLP)
- Text Extraction for Document Classification
Q: What type of text can Amazon Textract detect and extract?
A: Amazon Textract can detect Latin-script characters from the standard English alphabet and ASCII symbols.
Q: What document formats does Amazon Textract support?
A: Amazon Textract currently supports PNG, JPEG, and PDF formats. For synchronous APIs, you can submit images either as an S3 object or as a byte array. For asynchronous APIs, you can submit S3 objects.
Q: How do I get started with Amazon Textract?
A: To get started with Amazon Textract, you can click the “Get Started with Amazon Textract”, button on the Amazon Textract page. You must have an Amazon Web Services account; if you do not already have one, you will be prompted to create one during the process. Once you are signed in to your AWS account, try out Amazon Textract with your own images or PDF documents using the Amazon Textract Management Console. You can also download the Amazon Textract SDKs to start creating your own applications. Please refer to our step-by-step Getting Started Guide for more information.
Q: What APIs does Amazon Textract offer?
A: Amazon Textract offers APIs that detect and extract text from scanned images of documents, extracts structured data such as tables, and performs key-value pairing on extracted text. Amazon Textract performs OCR using the Detect Document Text API, but goes a step further in the document analyzing process and also performs key-value pair detection so that text extractions remain organized in their intended structure. The Analyze Document API can detect text, fields, values, their relationships, tables, and other entities within a document along with their associated confidence scores. With the Analyze Document API, developers can automatically capture structured data from a wide variety of documents including tax forms, financial reports, medical records, and loan applications. For details, please refer to the Amazon Textract API reference.
Q: How do I use the confidence score Amazon Textract provides?
A: A confidence score is a number between 0 and 100 that indicates the probability that a given prediction is correct. With Amazon Textract, all extracted text and structured data are returned with bounding box coordinates, which is a rectangular frame that fully encompasses each piece of data identified. This allows you to identify the score for each extracted entity so that you can make informed decisions on how you want to use the results.
Q: How can I get the best results from Amazon Textract?
A: Amazon Textract uses machine learning to read virtually any type of document, in order to extract text and structured information. Keep the following tips in mind in order to get the best results:
• Provide as high quality an image as you can, ideally at least 150 DPI.
• If your document is already in one of the file formats that Amazon Textract supports (PDF, JPG, PNG), don't convert or downsample it before uploading it to Amazon Textract.
• Amazon Textract's table feature works best when the tables in your document are visually separated from surrounding elements on the page (e.g. not overlaid on an image or complex pattern), and the text within the table is upright (e.g. not rotated relative to other text on the page)
Q: In which AWS regions is Amazon Textract available?
A: Amazon Textract is currently available in the US East (Northern Virginia), US East (Ohio), US West (Oregon), EU (Ireland), and EU (London).
Q: Does Amazon Textract work with AWS CloudTrail?
A: Yes. Amazon Textract supports logging of the following actions as CloudTrail events - DetectDocumentText, AnalyzeDocument, StartDocumentTextDetection, StartDocumentAnalysis, GetDocumentTextDetection, and GetDocumentAnalysis. For more details, please see Logging Amazon Textract API Calls with AWS CloudTrail.
Q: How does Amazon Textract count the number of pages processed?
A: An image (PNG or JPEG) counts as a single page. For PDFs, each page in the document is counted as a page processed.
Q: Which APIs am I charged for with Amazon Textract?
A: Refer to the Amazon Textract pricing page to learn more about pricing.
Q: How much does Amazon Textract cost?
A: Amazon Textract charges you based on the number of pages and images processed. For more information, visit the pricing page.
Q: Does Amazon Textract participate in the AWS Free Tier?
A: Yes. As part of the AWS Free Usage Tier, you can get started with Amazon Textract for free. New customers can analyze up to 1,000 pages per month using the Detecting Document Text API and up to 100 pages per month using the Analyze Document API, for the first three months.
