A coreference chain groups text mentions that refer to the same entity or discourse referent. In a spaCy document, Coreferee stores chains as lists of token references, allowing one mention to contain several tokens. section 11.5.1
Read a chain as a set of linked mentions:
- Each chain represents one distinct real-world object or discourse referent. section 11.5.1
- Each mention is represented by token positions, so a chain can contain single-token references or multi-token n-grams. section 11.5.1
- Indexed displays make connections easier to trace across sentence boundaries and support visualizations that share colors or draw graph edges. section 11.10 section 11.5.1
Wikipedia passage
For a passage about Gebru, Coreferee prints one chain as “Gebru(13), she(16), she(26), she(34)” and another as “advice(51), it(56).” The numbers are token positions; the grouped mentions identify two separate referents.
