Microsoft Certified: Azure AI Engineer AssociateImplement natural language processing solutionsEasy
A research institution is analyzing a large corpus of historical documents, many of which are scanned images of old manuscripts. To enable text-based search and analysis on these documents, the institution needs to convert the text within these images into machine-readable format. Which Azure AI service is required for this task?
- AAzure AI Vision for Optical Character Recognition (OCR)
- BAzure AI Speech for Batch Speech-to-Text
- CAzure AI Language for Key Phrase Extraction
- DAzure OpenAI Service for Text Summarization
Show answer & explanationAnswer & explanation
Correct answer: A. Azure AI Vision for Optical Character Recognition (OCR)
Optical Character Recognition (OCR) is the specific technology designed to extract text from images or scanned documents. Azure AI Vision provides robust OCR capabilities, which are essential for making historical scanned documents searchable and analyzable.
Why the other options are wrong
- B. Batch Speech-to-Text converts audio to text, not images to text.
- C. Key Phrase Extraction works on existing text, not for extracting text from images.
- D. Text Summarization works on existing text, not for extracting text from images.
Optical Character Recognition (OCR)
A technology that converts different types of documents, such as scanned paper documents, PDF files, or images captured by a digital camera, into editable and searchable data.
- Extracts text from images.
- Supports various languages and fonts.
- Crucial for digitizing physical documents.
- Part of Azure AI Vision.
Memory trick: OCR sees the text in pictures, turning them into searchable words.
