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

&lt;p&gt;If you would like to use this dataset as part of a research work, we would ask you to please consider citing our paper:&lt;/p&gt;

&lt;blockquote&gt;
&lt;p&gt;Jos&amp;eacute;-Miguel Herrera,&amp;nbsp;Aidan Hogan&amp;nbsp;and Tobias K&amp;auml;fer. &amp;quot;&lt;a href="http://aidanhogan.com/docs/btc2019.pdf"&gt;BTC-2019: The 2019 Billion Triple Challenge Dataset&amp;nbsp;&lt;/a&gt;&amp;quot;. In the Proceedings of the&amp;nbsp;18th International Semantic Web Conference (ISWC), Auckland, New Zealand, October 26&amp;ndash;30, 2019&amp;nbsp;(Resources track).&lt;/p&gt;
&lt;/blockquote&gt;

&lt;p&gt;The dataset is published in three main parts:&lt;/p&gt;

&lt;ol&gt;
	&lt;li&gt;&lt;strong&gt;Quads&lt;/strong&gt;:&lt;strong&gt;&amp;nbsp;(*nq.gz)&lt;/strong&gt;: contains the quads retrieved during the crawl (N-Quads, GZipped). These data are divided into individual files for each of the top 100&amp;nbsp;pay-level-domains by number of quads contributed&amp;nbsp;(btc2019-[&lt;em&gt;domain&lt;/em&gt;]_000XX.nq.gz).&amp;nbsp;While most domains have one file, larger domains are further split into parts (000XX)&amp;nbsp;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.&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;Triples&lt;/strong&gt;:&lt;strong&gt;&amp;nbsp;(btc2019-triples.nt.gz)&lt;/strong&gt;: 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.&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;VoID (void.nt)&lt;/strong&gt;: contains a &lt;a href="https://www.w3.org/TR/void/"&gt;VoID&lt;/a&gt; file offering statistics about the dataset.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;For parsing the files, we recommend a streaming parser, such as &lt;a href="http://librdf.org/raptor/rapper.html"&gt;Raptor&lt;/a&gt;, &lt;a href="http://docs.rdf4j.org/programming/#_parsing_and_writing_rdf_with_rio"&gt;RDF4j/Rio&lt;/a&gt;, or &lt;a href="https://github.com/nxparser/nxparser"&gt;NxParser&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;The data are sourced from&amp;nbsp;2,641,253 RDF documents. The &lt;strong&gt;top-10&amp;nbsp;pay-level-domains in terms of documents&lt;/strong&gt; contributed are:&lt;/p&gt;

&lt;ol&gt;
	&lt;li&gt;&lt;em&gt;dbpedia.org&lt;/em&gt; 162,117 documents (6.14%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;loc.gov&lt;/em&gt; 150,091 documents (5.68%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;bnf.fr&lt;/em&gt; 146,186 documents (5.53%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;sudoc.fr&lt;/em&gt; 144,877 documents (5.49%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;theses.fr&lt;/em&gt; 141,228 documents (5.35%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;wikidata.org&lt;/em&gt; 141,207 documents (5.35%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;linkeddata.es&lt;/em&gt; 130,459 documents (4.94%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;getty.edu&lt;/em&gt; 130,398 documents (4.94%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;fao.org&lt;/em&gt; 92,838 documents (3.51%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;ontobee.org&lt;/em&gt; 92,812 documents (3.51%)&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;The data contain&amp;nbsp;2,155,856,033 quads. The &lt;strong&gt;top-10&amp;nbsp;pay-level-domains in terms of quads&lt;/strong&gt;&amp;nbsp;contributed are:&lt;/p&gt;

&lt;ol&gt;
	&lt;li&gt;&lt;em&gt;wikidata.org&lt;/em&gt; 2,006,338,975 quads (93.06%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;dbpedia.org&lt;/em&gt; 36,686,161 quads (1.70%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;idref.fr&lt;/em&gt; 22,013,225 quads (1.02%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;bnf.fr&lt;/em&gt; 12,618,155 quads (0.59%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;getty.edu&lt;/em&gt; 7,453,134 quads (0.35%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;sudoc.fr&lt;/em&gt; 7,176,301 quads (0.33%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;loc.gov&lt;/em&gt; 6,725,390 quads (0.31%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;linkeddata.es&lt;/em&gt; 6,485,114 quads (0.30%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;theses.fr&lt;/em&gt; 4,820,874 quads (0.22%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;ontologycentral.com&lt;/em&gt; 4,633,947 quads (0.21%)&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;The data contain&amp;nbsp;256,059,356 unique triples. The &lt;strong&gt;top-10&amp;nbsp;pay-level-domains in terms of unique triples&lt;/strong&gt;&amp;nbsp;contributed are:&lt;/p&gt;

&lt;ol&gt;
	&lt;li&gt;&lt;em&gt;wikidata.org&lt;/em&gt; 133,535,555 triples (52.15%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;dbpedia.org&lt;/em&gt; 32,981,420 triples (12.88%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;idref.fr&lt;/em&gt; 16,820,681 triples (6.57%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;bnf.fr&lt;/em&gt; 11,769,268 triples (4.60%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;getty.edu&lt;/em&gt; 6,571,525 triples (2.57%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;linkeddata.es&lt;/em&gt; 5,898,762 triples (2.30%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;loc.gov&lt;/em&gt; 5,362,064 triples (2.09%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;sudoc.fr&lt;/em&gt; 4,972,647 triples (1.94%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;ontologycentral.com&lt;/em&gt; 4,471,962 triples (1.75%)&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;theses.fr&lt;/em&gt; 4,095,897 triples (1.60%)&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;To merge these files into one (again on Unix):&lt;/p&gt;

&lt;pre&gt;&lt;code&gt;cat *.nq.gz &amp;gt; btc2019-quads.nq.gz_bak
mv btc2019-quads.nq.gz_bak btc2019-quads.nq.gz&lt;/code&gt;&lt;/pre&gt;

&lt;p&gt;&amp;nbsp;&lt;/p&gt;
