web_graph

  • Description:

This dataset contains a sparse graph representing web link structure for a small subset of the Web.

Its a processed version of a single crawl performed by CommonCrawl in 2021 where we strip everything and keep only the link->outlinks structure. The final dataset is basically int -> List[int] format with each integer id representing a url.

Also, in order to increase the value of this resource, we created 6 different version of WebGraph, each varying in the sparsity pattern and locale. We took the following processing steps, in order:

  • We started with WAT files from June 2021 crawl.
  • Since the outlinks in HTTP-Response-Metadata are stored as relative paths, we convert them to absolute paths using urllib after validating each link.
  • To study locale-specific graphs, we further filter based on 2 top level domains: ‘de’ and ‘in’, each producing a graph with an order of magnitude less number of nodes.
  • These graphs can still have arbitrary sparsity patterns and dangling links. Thus we further filter the nodes in each graph to have minimum of K ∈ [10, 50] inlinks and outlinks. Note that we only do this processing once, thus this is still an approximation i.e. the resulting graph might have nodes with less than K links.
  • Using both locale and count filters, we finalize 6 versions of WebGraph dataset, summarized in the folling table.
Version Top level domain Min count Num nodes Num edges
sparse 10 365.4M 30B
dense 50 136.5M 22B
de-sparse de 10 19.7M 1.19B
de-dense de 50 5.7M 0.82B
in-sparse in 10 1.5M 0.14B
in-dense in 50 0.5M 0.12B

All versions of the dataset have following features:

  • "row_tag": a unique identifier of the row (source link).
  • "col_tag": a list of unique identifiers of non-zero columns (dest outlinks).

  • "gt_tag": a list of unique identifiers of non-zero columns used as ground truth (dest outlinks), empty for train/train_t splits.
