What are Masked Language Models

GlossaryLanguage Models and Natural Language Processing

Language models trained to predict hidden words or tokens from surrounding context.

Definition

Masked Language Models is language models trained to predict hidden words or tokens from surrounding context. In practical AI work, it helps teams connect a concept to data, model behavior, product choices and evaluation. The useful question is not only what the term means, but how it affects quality, cost, reliability and risk in a real workflow.

Example

A text or speech system uses Masked Language Models to process user input and return an answer that better matches the task and language.

Why it matters

Masked Language Models matters because language models trained to predict hidden words or tokens from surrounding context can change how teams build, evaluate or choose AI systems.

How it works

The system represents text, analyzes structure or meaning, and evaluates whether outputs match the task and context. For Masked Language Models, the key is to connect the definition with input data, assumptions, measurable outcomes and deployment limits.

Where it is used

  • Used in chatbots, search, summarization, extraction, translation and text analytics.

Limitations

Language systems may miss context, repeat bias, hallucinate details or fail on domain-specific wording.
