Question
The application scans a document with a lot of pages. It returns the following information for each page: page information, lines information, and words for each line with a confidence level.
What API does the application use to scan the document?
A. OCR
B. NLP
C. Read
D. Text Analytics
E. LUIS
Answer
C. Read
Explanation
Read API is part of Computer Vision services. It helps to “read” texts within predominantly document images. Read API is an asynchronous service specially designed for the heavy on text images or documents with many distortions. It produces a result that includes: page information for each page, including page size and orientation; information about each line on the page, and information about each word in each line, including the bounding box of each word as an indication of the word position in the image.
Option A is incorrect since OCR API is a synchronous service for recognizing small amounts of text in the images. It returns regions of the text in the image, lines of the text in the region, and words in each line.
Option B is incorrect since Natural Language Processing (NLP) is one of the key elements of Artificial Intelligence and is not the part of Computer Vision that deals with text extraction from the images.
Option D is incorrect since Text Analytics is the part of Natural Processing Language (NLP) and is not the part of Computer Vision that deals with text extraction from the images.
Option E is incorrect since Language Understanding Intelligent Service (LUIS) is the part of Natural Processing Language (NLP) and is not the part of Computer Vision that deals with text extraction from the images.
