[with postdoctoral fellow Nick Diakopoulos]
research questions how can (Twitter) content contributed around large-scale broadcast news events inform journalistic inquiry? what kinds of insights and analyses are enabled through visual analytic tools?
designing for journalism divergent points of view newsworthiness: surprising, unusual, extremes of positive / negative
supporting analysis direct attention to relevant information automatic content analysis for filtering – relevance – uniqueness / novelty – sentiment – keyword extraction
how to evaluate? directly evaluate the output of the algorithms (quantitative) deep, extensive evaluation of users’ interaction with the system (qualitative)

Vox evaluation goals • How effective for generating story ideas? • What kind of insights/analysis are supported? • Shortcomings and how features are used?
Vox evaluation: framing • “develop two story pitches for the event” • open-ended questionnaires, content analysis • 18 participants
