AI-900: What AI Service Interprets User Input Meaning Like “Call Me Back Later”?

Learn which Microsoft Azure AI service can interpret the meaning and intent behind natural language user inputs such as “Call me back later”. Discover how Language Understanding (LUIS) enables your applications to intelligently process and respond to user queries and commands.

Question

Select an AI service, which can be used to interpret the meaning of a user input such as Call me back later. Select the correct service.

A. Text Analytics.
B. Speech.
C. Language Understanding (LUIS).
D. Translator.

Answer

C. Language Understanding (LUIS).

Explanation

Language Understanding (LUIS) is the correct Azure AI service to interpret the meaning and intent behind a user input such as “Call me back later”.

LUIS is a natural language processing (NLP) service that allows you to build custom machine learning models to understand user utterances. It can extract the intent (the overall goal or purpose) as well as any relevant entities (key pieces of information) from natural language inputs.

For the example “Call me back later”:

• LUIS would identify the intent as something like “ScheduleCallback” or “RequestCallBack”. This captures the user’s desire to receive a return call.
• LUIS would also extract the entity “later” referring to the requested callback time. Your application could then use this to schedule the callback appropriately.

The other options, while useful Azure AI services, do not directly interpret intent from user language:

• Text Analytics extracts information like sentiment, key phrases, and named entities from text, but doesn’t determine intent.
• Speech converts spoken audio to text (speech-to-text) and vice versa (text-to-speech), but doesn’t inherently understand the text’s meaning.
• Translator translates text between languages, but does not extract intent.

So in summary, Language Understanding (LUIS) is the Azure AI service specifically designed to interpret user intent and extract relevant information from natural language, enabling more intelligent and intuitive conversational AI applications. Its ability to understand inputs like “Call me back later” makes it the correct choice for this scenario.

Language Understanding (LUIS) is an AI service designed to interpret the meaning and intent behind user input, such as “Call me back later.” It helps in understanding the context and the user’s intended action from natural language.
