Question
Which Azure AI Language feature can be used to retrieve data, such as dates and people’s names, from social media posts?
A. Entity recognition
B. Speech recognition
C. Key phrase extraction
D. Language detection
Answer
A. Entity recognition
Explanation
The correct Azure AI Language feature for this scenario is A. Entity recognition. This feature is designed to identify and categorize specific pieces of information within unstructured text.
Understanding Entity Recognition
Entity recognition, also known as Named Entity Recognition (NER), is a core capability of natural language processing that locates and classifies named entities in text into pre-defined categories. For the task of retrieving data from social media posts, this feature can automatically identify and extract:
- People’s Names: It can recognize names of individuals mentioned in a post.
- Dates and Times: It identifies absolute and relative dates, such as “tomorrow,” “October 5th,” or “next week.”
- Locations: It can extract names of cities, countries, and landmarks.
- Organizations: It identifies companies and institutions.
This allows you to take unstructured text, like a social media post, and extract structured, actionable data from it.
Why Other Options Are Incorrect
- Speech recognition: This service converts spoken audio into written text. It does not analyze existing text to extract data from it.
- Key phrase extraction: This feature identifies the main topics or talking points in a text, such as “great concert” or “new project.” It provides high-level concepts rather than specific, categorized entities like a person’s name or a specific date.
- Language detection: This feature simply determines the language in which the text is written (e.g., English, Spanish, French). It does not analyze the content of the text itself.
