AI-900 Practice Question: Describe features of Natural Language Processing workloads on Azure
What is the purpose of Azure AI Language's 'entity linking' feature?
⚠ Common exam trap
A common mix-up: candidates confuse entity linking with simple entity extraction (which only identifies entities without disambiguation) or assume it creates hyperlinks, when in fact it resolves ambiguity by connecting to a knowledge base.

Correct answer & explanation
✓
Identifying entities in text and connecting them to a knowledge base to disambiguate meaning
Entity linking in Azure AI Language identifies named entities in text and disambiguates them by linking to a corresponding entry in a knowledge base, such as Wikipedia or Microsoft's internal knowledge graph. This resolves cases where the same name could refer to multiple real-world entities (e.g., 'Washington' could be a state, a person, or a city), ensuring the correct meaning is assigned.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Creating hyperlinks in documents to connect related sections
Why it's wrong here
Creating hyperlinks is a manual word-processing feature that defines navigational paths between sections or pages; it does not perform any language understanding or semantic analysis. Entity linking, by contrast, is an NLP feature that scans text for named-entity mentions and resolves each one to a unique identifier in a knowledge base, such as distinguishing the planet Mercury from the element. Hyperlinks simply jump between locations, whereas entity linking disambiguates meaning by connecting the mention to a specific real-world entity, so this option is incorrect.
- ✓
Identifying entities in text and connecting them to a knowledge base to disambiguate meaning
Why this is correct
Entity linking is the correct definition: it identifies entity mentions in text and connects each mention to a knowledge base entry to disambiguate its meaning. For example, the word 'Mercury' may refer to a planet, a chemical element, or a Roman god; entity linking uses the surrounding context to select the proper knowledge-base record. Azure AI Language's entity linking feature returns the resolved entity ID and often a Wikidata link, providing a precise, unambiguous identifier for downstream applications.
- ✗
Linking multiple Azure AI Language projects together
Why it's wrong here
Linking multiple Azure AI Language projects together describes orchestration or composition of AI services, such as chaining a language model to custom question-answering or LUIS projects, which is an architectural and configuration pattern. Entity linking is a single AI-powered feature that analyzes text to identify entity mentions and associate them with knowledge-base records. The two uses of 'linking' are different: project linking is about service management, while entity linking is about semantic disambiguation of text references, so this option is incorrect.
- ✗
Connecting extracted entities to a CRM database for business intelligence
Why it's wrong here
Connecting extracted entities to a CRM is a downstream integration step, not the definition of entity linking. While resolved entity identifiers could be used for business intelligence dashboards, the actual entity-linking operation is an NLP task that maps mentions to a knowledge base like Wikidata to resolve ambiguity. The CRM connection is a data-pipeline design pattern and is orthogonal to the core language-understanding capability that entity linking provides, so this option is incorrect.
