NewsViews

  1. 1. ACM CHI 2014 NewsViews: An Automated Pipeline for Creating Custom Geovisualizations for News
  2. 2. Online news is a preferred source of information among many individuals.
  3. 3. Data visualizations can add context to news, making trends in the article more tangible.
  4. 4. Maps are particularly helpful for news articles that contain mentions of locations. They can orient a user to unfamiliar locations,
  5. 5. and summarize data important to the story.
  6. 6. Annotated maps deliver more content with text explanations of interesting data points.
  7. 7. For instance, what data best summarizes the article topic? However, the decisions involved with generating a visualization to accompany an article are complex.
  8. 8. Should the visualization focus on data at different locations, or across different time periods? What is the best content for creating annotations? Where should they be placed?
  9. 9. There are millions of articles, but professional news visualization designers are scarce.
  10. 10. NewsViews automates a complex news visualization pipeline, making it possible to scale visualization creation to large sets of articles. +
  11. 11. For example, given an article about obesity in the U.S., NewsViews presents a map of county- level obesity rates.
  12. 12. Important locations in the article are labeled, and annotations display content from other relevant articles about the location and topic.
  13. 13. The NewsViews system in action:
  14. 14. NewsViews can also generate line graphs, when an article focuses on comparisons across time.
  15. 15. NewsViews works by extracting key features (places, topics, etc.) from an article, and selecting relevant “data views” from a table database.
  16. 16. A visualization generator creates multiple visualizations of each view, including choosing a visual format and annotating the visualization with articles from a news corpus.
  17. 17. The most relevant and ‘visually interesting’ visualization is then chosen from the set and presented to the news reader.
