Nasty.Language.English.CoreferenceResolver (Nasty v0.3.0)

View Source

Coreference Resolution for English.

This is a thin wrapper around the generic coreference resolution modules. It provides English-specific configuration and delegates to the generic resolver for the actual algorithm.

Links referring expressions (pronouns, definite NPs, proper names) across sentences to build coreference chains representing entities.

Uses rule-based heuristics with agreement constraints (gender, number) and salience-based scoring (recency, syntactic position).

Examples

iex> document = parse_document("John works at Google. He is an engineer.")
iex> {:ok, chains} = CoreferenceResolver.resolve(document)
iex> chain = List.first(chains)
iex> chain.representative
"John"
iex> length(chain.mentions)
2

@spec resolve(
  Nasty.AST.Document.t(),
  keyword()
) :: {:ok, [Nasty.AST.Semantic.CorefChain.t()]} | {:error, term()}

Resolves coreferences in a document.

Delegates to the generic resolver with English-specific configuration.

Options

  • :min_score - Minimum score threshold for coreference (default: 0.3)
  • :merge_strategy - Clustering linkage type (default: :average)
  • :weights - Custom scoring weights

Returns

  • {:ok, chains} - List of coreference chains
  • {:error, reason} - Resolution error
