# Wiki Entity Similarity

This dataset is generated by aggregating the link text that refers to various articles in context. For instance, if wiki article A refers to article B as C, then C is added to the list of aliases for article B, and the pair (B, C) is included in the dataset.

Following (DPR https://arxiv.org/pdf/2004.04906.pdf), we use the English Wikipedia dump from Dec. 20, 2018 as the source documents for link collection. 

The dataset includes three quality levels, distinguished by the minimum number of inbound links required to include an article in the dataset. This filtering is motivated by the heuristic "better articles have more citations."

| Min. Inbound Links | Number of Articles | Number of Distinct Links |
|------------|--------------------|--------------------------|
| 5 | 1,080,073 | 5,787,081 |
| 10 | 605,775 | 4,407,409 |
| 20 | 324,949 | 3,195,545 |
