Abstract

This paper describes the extraction of information on lethal events from the Swedish version of Wikipedia. The information searched includes the persons’ cause of death, origin, and profession. We carried out the extraction using a processing pipeline of available tools for Swedish including a part-of-speech tagger, a dependency parser, and manually-written extraction rules. We also extracted structured semantic data from the Wikidata store that we combined with the information retrieved from Wikipedia. Eventually, we gathered a database of facts that covers both sources: Wikipedia and Wikidata.
