    <subfield code="a">&lt;p&gt;WikiEvents is a knowledge graph based dataset for NLP and event-related machine learning tasks.&lt;/p&gt;

&lt;p&gt;This dataset includes RDF data in JSON-LD about events between January 2020 and December 2022. It was extracted from the Wikipedia Current events portal, Wikidata, OpenStreetMaps Nominatim and Falcon 2.0. The extractor is available on GitHub under &lt;a href="https://github.com/semantic-systems/current-events-to-kg"&gt;semantic-systems/current-events-to-kg&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;The RDF data for each month is split onto four graph modules each:&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;The &lt;strong&gt;base&lt;/strong&gt; graph module contains events, event summaries with references from named entities to Wikipedia articles.&lt;/li&gt;
	&lt;li&gt;The &lt;strong&gt;ohg&lt;/strong&gt; graph module with all one-hop graphs (ohg) around the referencend Wikidata entities.&lt;/li&gt;
	&lt;li&gt;The &lt;strong&gt;osm&lt;/strong&gt; graph module which contains spartial data from OpenStreetMap (OSM).&lt;/li&gt;
	&lt;li&gt;The &lt;strong&gt;raw&lt;/strong&gt; graph module containing the raw HTML objects of events and article infoboxes.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;This repository additionally includes two JSON files with training samples used for entity linking and event-related location extraction. They were created using queries to the WikiEvents dataset uploaded into this repository.&lt;/p&gt;</subfield>
