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
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(enrichedTitle.entities.type:Person).term(enrichedTitle.entities.text,count:100)&count=0
