Correct Answer: C

Explanation:
Sentence and text completion depend on predicting the next word or phrase, which is a fundamental feature of language modeling.

Question 4

Which feature distinguishes modern language models from earlier rule-based NLP systems?

A. They rely only on predefined grammar rules
B. They can understand context across multiple words or sentences
C. They only work with structured data

Question 6

A customer support system automatically answers user questions using natural language. Which AI capability is primarily being used?

A. Object detection
B. Language modeling
C. Key phrase extraction
D. Speech synthesis

Correct Answer: B

Explanation:
Automatically generating answers in natural language relies on language modeling, especially for conversational and question-answering scenarios.

Question 7

Which task is least likely to use language modeling?

A. Generating a summary of a document
B. Translating text between languages
C. Detecting the sentiment of a sentence
D. Producing a chatbot response

Correct Answer: C

Explanation:
Sentiment analysis focuses on identifying emotional tone, not generating or predicting text. The other options rely heavily on language modeling.

Question 8

Why are pretrained language models commonly used in Azure AI solutions?

A. They eliminate the need for any data
B. They require less storage than traditional models
C. They can be used immediately without custom training
D. They only support English language text

Correct Answer: C

Explanation:
Pretrained models are already trained on large datasets and can be used out of the box, which aligns with Azure’s AI service approach.

Question 9

Which statement best describes how language models generate text?

A. By randomly selecting words from a dictionary
B. By applying fixed grammatical rules
C. By predicting the most likely next word in a sequence
D. By translating text into numerical values only

Correct Answer: C

Explanation:
Language models generate text by calculating probabilities of word sequences and selecting the most likely continuation.

Question 10

A solution needs to create readable paragraphs based on a short prompt provided by a user. Which AI capability should be used?

A. Optical character recognition
B. Speech recognition
C. Language modeling
D. Image classification

Correct Answer: C

Explanation:
Generating paragraphs from a prompt is a classic language modeling use case involving text prediction and generation.

Identify Features and Uses for Language Modeling (AI-900 Exam Prep)

Overview

Language modeling is a core concept in Natural Language Processing (NLP) that focuses on enabling machines to understand, generate, and predict human language. In the context of the AI-900 exam, language modeling is not about building models from scratch, but about recognizing what language models do, what problems they solve, and how Azure provides access to them.

Language models power many modern AI experiences, including chatbots, text generation, summarization, translation, and question answering.

What Is a Language Model?

A language model is a type of AI model that learns patterns in language so it can:

  • Predict the next word or token in a sequence
  • Understand context and meaning
  • Generate coherent and contextually relevant text

At a fundamental level, language models calculate the probability of word sequences, which allows them to both interpret and generate language.

Key Features of Language Modeling

1. Text Prediction and Generation

Language models can:

  • Predict the next word in a sentence
  • Generate full sentences, paragraphs, or documents
  • Produce human-like responses in conversations

Example:

“The weather today is very…” → sunny

2. Context Awareness

Modern language models (especially transformer-based models) consider context, not just individual words.

This allows them to:

  • Understand sentence meaning
  • Maintain coherence across multiple sentences
  • Respond appropriately based on prior text

3. Natural Language Understanding and Generation

Language models support both:

  • Understanding text (reading and interpreting meaning)
  • Generating text (writing responses, summaries, or explanations)

This dual capability is central to many NLP workloads.

4. Pretrained Models

In Azure, language modeling typically relies on pretrained models, meaning:

  • No custom training is required
  • Models are already trained on large text datasets
  • Users can immediately apply them to common NLP tasks

This aligns with the AI-900 focus on consuming AI services, not building models.

Common Uses of Language Modeling

1. Chatbots and Virtual Assistants

Language models enable conversational AI by:

  • Understanding user input
  • Generating natural responses
  • Maintaining conversation context

Azure Example:
Chatbots built using Azure OpenAI Service or language-based Azure AI services.

2. Text Completion and Content Generation

Language models can:

  • Auto-complete sentences
  • Generate emails, reports, or documentation
  • Assist with creative writing or code comments

3. Question Answering

Language models can:

  • Interpret natural language questions
  • Generate relevant answers based on context or provided data

This is commonly used in:

  • Help desks
  • Knowledge bases
  • Internal support tools

4. Text Summarization

Language models can:

  • Condense long documents
  • Extract key points
  • Provide concise summaries

This helps users quickly understand large volumes of text.

5. Language Translation and Adaptation

While translation is often a separate NLP workload, language models:

  • Understand sentence structure
  • Preserve meaning across languages
  • Adapt phrasing naturally

Language Modeling in Azure

In Azure, language modeling capabilities are available through services such as:

Azure OpenAI Service

  • Provides access to powerful large language models
  • Supports text generation, chat, summarization, and reasoning tasks
  • Uses pretrained transformer-based models

Azure AI Language

  • Focuses on structured NLP tasks
  • Complements language modeling with features like sentiment analysis and entity recognition

For AI-900, it’s important to recognize what language models enable, not the underlying implementation details.

Language Modeling vs Other NLP Tasks (Exam Tip)

NLP TaskFocus
Sentiment analysisEmotional tone
Entity recognitionIdentifying names, places, organizations
Key phrase extractionImportant terms
Language modelingUnderstanding and generating language

If the question involves predicting, generating, or responding with text, language modeling is likely the correct concept.

Why Language Modeling Matters for AI-900

Microsoft includes language modeling in AI-900 to ensure candidates understand:

  • How modern AI systems interact with human language
  • Why conversational AI is possible
  • How Azure provides ready-to-use NLP capabilities

You are not expected to train models — only to identify features, uses, and scenarios.

Exam Takeaway

If a question mentions:

  • Text generation
  • Conversational AI
  • Predicting words or sentences
  • Understanding context in language
