> 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.
> Wikilinks is one of the result of this task. 
> Wikilinks dataset comprising of 40 million mentions over 3 million entities. The 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, we are able to include many styles of text beyond newswire and many entity types beyond people.
> UMass has created expanded versions of the dataset containing the following extra features:
> * Complete webpage content (with cleaned DOM structure)
> * Extracted context for the mentions
> * Alignment to Freebase entities
> The expanded dataset can be downloaded from http://iesl.cs.umass.edu/downloads/wiki-link/context-only/
> A tool is needed in order to parser this information and store it in any type of storage like Jena TDB. 
> Wikilinks provides information of documents with mentions to Freebase entities and this information can be used both to desambiguate and to merge with the Freebase information in order to have a large set of valuable data.
