Link debates to news items
Link debates to news itemsIntuition 1: The news item contains a topic a/o name of a politician and is published within a week after a debate
Intuition 2: The more overlap in topics and named entities, the more probably there is a link.
Not only USE data
Also GIVE data
“Give me all fragments of debates with over 60 related news items”
SELECT ?speech ?no_newsitems {{ SELECT ?speech (COUNT(?news) AS ?no_news_items)WHERE{
?speech <http://purl.org/linkedpolitics/nl/polivoc#coveredAt> ?news .
}GROUP BY ?speech }FILTER (?no_news_items > 60) }
