Spotlight shows users the latest headlines, a rundown of how the story has developed over time, and relevant social media posts from people around the web. Spotlight also shows diverse perspectives on a given topic so users can quickly get a well-rounded view on the topic before deciding what they want to go deeper on and read by clicking on any of the articles.
Users’ trust in the news we present is of the utmost importance to Bing, and we’re committed to providing a well-rounded view of news from diverse, quality sources.
To start, Bing monitors millions of queries and news articles every day and identifies impactful stories that evolve over a period of weeks or months. We look at various user signals such as queries and browser logs, and document signals from publishers such as how many publishers cover a story, their angles, and how prominently they feature the story on their site. For controversial topics, in the Perspectives module, we show different viewpoints from high-quality sources.
Behind the scenes, we leverage our deep learning algorithms and web graphs of hundreds of millions of web sites in the Bing index to identify top sources for national news, per category, query, or article. Our goal is to provide broader context for impactful stories, from politics to business to major disasters, and much more.
