Wikidata dump extension (enwiki section links)

<p>The dataset contains mappings between Wikidata entities and Wikipedia sections.&nbsp;The mappings come in addition to the existing Wikidata sitelinks referencing&nbsp;Wikipedia pages.</p> <p>The creation of the present dataset stems from the observation that only a fraction of Wikidata entities has&nbsp;a corresponding Wikipedia article in any language (we refer to the remaining entities, without an article, as orphans). However, a substantial number of orphan entities are indeed available in Wikipedia, but not at the page level; orphan entities can be described within existing Wikipedia articles in the form of sections, subsections, and paragraphs of a more generic concept or fact. The&nbsp;dataset provides&nbsp;a fine-grained mapping between Wikidata orphan entities and Wikipedia (sub)-sections.</p> <p>Mappings are provided for English language.</p> <p>The dataset is available in&nbsp;JSON and RDF formats and complies&nbsp;with the&nbsp;Wikibase data model.</p> <p>In the JSON representation, an entity contains two fields:&nbsp;<em>id</em>&nbsp;(the unique identifier of an entity) and&nbsp;<em>sectionlinks</em>&nbsp;(links to Wikipedia sections). Each sectionlink record comprises a list of records¹ with&nbsp;three fields:<em>&nbsp;site, title,</em>&nbsp;and&nbsp;<em>url.</em>&nbsp;A section title is appended to the page title separated with # symbol. Such a compound title is then URL-encoded and added to the URL path. Following the Wikidata guidelines, each entity is encoded as a single line.</p> <p>Example:</p> <pre><code class="language-json">{ "id": "Q715509", "sectionlinks": { "enwiki": [ { "site": "enwiki", "title": "Places in Harry Potter#Azkaban", "url": "https://en.wikipedia.org/wiki/Places_in_Harry_Potter#Azkaban" } ], } }</code></pre> <p>&nbsp;</p> <p>The RDF dump is serialized using the Turtle format and stores nodes describing Wikipedia links. Section titles are added in the same manner as described above.</p> <p>Example:</p> <pre><code>&lt;https://en.wikipedia.org/wiki/Places_in_Harry_Potter#Azkaban&gt; a schema:Article ; schema:about wd:Q715509 ; schema:inLanguage "en" ; schema:isPartOf &lt;https://en.wikipedia.org/&gt; ; schema:name "Places in Harry Potter#Azkaban"@en . &lt;https://en.wikipedia.org/&gt; wikibase:wikiGroup "wikipedia" . </code></pre> <p>&nbsp;</p> <p>¹&nbsp;As opposed to sitelinks, where&nbsp;each entity can be mapped with a unique&nbsp;Wikipedia page&nbsp;(one-to-one&nbsp;mapping), in sectionlinks we&nbsp;&nbsp;allow a one-to-many&nbsp;mapping, i.e., an entity can be mapped to&nbsp;multiple sections.&nbsp;For example, <em>Tennis racket</em>&nbsp;concept can be mapped to <em>Tennis#Rackets</em>&nbsp;and <em>Racket (sports equipment)#Tennis</em>&nbsp;sections.</p>
