What is Coreference Resolution

GlossaryNatural Language Processing

The task is to determine which words or phrases in the text refer to the same object.

Definition

Coreference Resolution is the task of determining which words or phrases in a text refer to the same object. To put it simply, this concept helps process text and speech and assess the quality of language systems. In practice, it helps to understand what capabilities the tool actually has, what data it will need, and what limitations are worth checking before implementation.

Example

In the phrase Anna called Maria because she was waiting for an answer, the model must understand who exactly was waiting for the answer.

Why it matters

Coreference improves understanding of documents, dialogues, retellings and answers to long texts. This helps you choose AI tools not by big promises, but by how they work in a real problem.

How it works

Text or speech is broken down into useful representations, then the model extracts the meaning, connections, intent, or quality of the output. In the case of the term “Coreference Resolution”, it is important to look separately at the data, quality criteria and application conditions.

Where it is used

  • Found in translators, search, chatbots, speech recognition, document analysis and summarization.

Limitations

Quality depends on the language, context, domain, markup, and how well the system understands ambiguous language.
