The world of Journalists is changing. Their business model seems to vanish. That is not really true. Their world is only shifting. This lecture focus on the change brought to Journalists by Big Data.
Big Data is "hype-term" but “being data-driven” creates new possibilities for Journalists. The talk goes through the 5 V's of Big Data and why we should focus on small Data.
Several use-cases for Journalists are discussed from Influencers over Reach Metrics to Trend Prediction and Content Validation. A few tools supporting the Journalistic work are introduced.
