Wikilinks: a Large-Scale Cross-Document Coreference Corpus Labeled via Links to Wikipedia - scientific work related to Wikipedia quality published in 2012, written by Sameer Singh, Amarnag Subramanya, Fernando Pereira and Andrew McCallum.
Overview
Cross-document coreference resolution is the task of grouping the entity mentions in a collection of documents into sets that each represent a distinct entity. It is central to knowledge base construction and also useful for joint inference with other NLP components. Obtaining large, organic labeled datasets for training and testing cross-document coreference has previously been difficult. This paper presents a method for automatically gathering massive amounts of naturally-occurring cross-document reference data. Authors also present the Wikilinks dataset comprising of 40 million mentions over 3 million entities, gathered using this method. Authors method is based on finding hyperlinks to Wikipedia from a web crawl and using anchor text as mentions. In addition to providing large-scale labeled data without human effort, authors are able to include many styles of text beyond newswire and many entity types beyond people.
