  4. 4. 4 Discovery: News The Watson Discovery Service provides a pre-enriched set of news articles – over 300,000 a day! With the query API, it is easy to look at trends and aggregations across hundreds of sources.
  5. 5. 5 Aggregation query  This core of this app is an aggregation query over recent news articles. The question being asked is "For articles that contain a given search term in the title, who are the people most frequently mentioned?"  The query breaks down into three parts: query: title:{keyword} aggregation: nested(enrichedTitle.entities) .filter(enrichedTitle.entities.type:Person) .term(enrichedTitle.entities.text,count:100) count: 0  The full query URL looks like this: https://gateway.watsonplatform.net/discovery/api/v1/environments/{environment ID}/collections/{collection ID}/query?version=2016-11- 07&query=title:{keyword}&aggregation=nested(enrichedTitle.entities).filter(enriched Title.entities.type:Person).term(enrichedTitle.entities.text,count:100)&count=0
