Billion Triple Challenge (BTC) 2019 Dataset

Herrera, Jose Miguel; Hogan, Aidan; Käfer, Tobias

The Billion Triple Challenge (BTC) 2019 Dataset is the result of a large-scale RDF crawl (accepting RDF/XML, Turtle and N-Triples) conducted from 2018/12/12 until 2019/01/11 using LDspider. The data are stored as quads where the fourth element encodes the location of the Web document from which the associated triple was parsed. The dataset contains 2,155,856,033 quads, collected from 2,641,253 RDF documents on 394 pay-level domains. Merging the data into one RDF graph results in 256,059,356 unique triples. These data (as quads or triples) contain 38,156 unique predicates and instances of 120,037 unique classes.

If you would like to use this dataset as part of a research work, we would ask you to please consider citing our paper:

José-Miguel Herrera, Aidan Hogan and Tobias Käfer. "BTC-2019: The 2019 Billion Triple Challenge Dataset ". In the Proceedings of the 18th International Semantic Web Conference (ISWC), Auckland, New Zealand, October 26–30, 2019 (Resources track).

The dataset is published in three main parts:

  1. Quads: (*nq.gz): contains the quads retrieved during the crawl (N-Quads, GZipped). These data are divided into individual files for each of the top 100 pay-level-domains by number of quads contributed (btc2019-[domain]_000XX.nq.gz). While most domains have one file, larger domains are further split into parts (000XX) with approximately 150,000,000 quads each. Finally, quads from the 294 domains not in the top 100 are merged into one file: btc2019-other_00001.nq.gz.
  2. Triples: (btc2019-triples.nt.gz): contains the unique triples resulting from taking all quads, dropping the fourth element (indicating the location of the source document) and computing the unique triples.
  3. VoID (void.nt): contains a VoID file offering statistics about the dataset.

For parsing the files, we recommend a streaming parser, such as Raptor, RDF4j/Rio, or NxParser.

The data are sourced from 2,641,253 RDF documents. The top-10 pay-level-domains in terms of documents contributed are:

  1. dbpedia.org 162,117 documents (6.14%)

  10. ontologycentral.com 4,633,947 quads (0.21%)

The data contain 256,059,356 unique triples. The top-10 pay-level-domains in terms of unique triples contributed are:

  1. wikidata.org 133,535,555 triples (52.15%)
  2. dbpedia.org 32,981,420 triples (12.88%)
