Technical Definition

The NLP task of identifying all expressions that refer to the same entity in a text.

How it works

Coreference resolution links pronouns, nouns, and other linguistic expressions back to the entities they refer to. For instance, in 'John went to the store. He bought apples,' 'He' refers to 'John'. This is critical for natural language understanding to correctly interpret relationships and entities across sentences, improving text summarization and question answering.
