Exploratory Study Online Survey (n=28), 2 group discussions (n=35) Past Experiences (Memorable Events) Existing Technologies • Discovery • Opinions Scenarios • Decision making • Interests Requirements • Registering & sharing • Suggestions 1st Design Concept • Meaningful relationships • Benefits/drawbacks 04/05/2010 - What's on this evening?

Conclusions • Opinions seem support the development of an environment that merges the three technologies (information enrichment) • There is a need to support different visualizations and better browsing – Common concern about information overload – Lack of event coverage and information completeness supports combining multiple information sources 04/05/2010 - What's on this evening? Designing User Support for Event-based Annotation and Exploration of Media - EVENTS 2010, Athens, Greece 21

Data Challenges • Semantization of Data (events, media, users) • Association – Linking media and events (#) + Heuristics – Linking events to people, identifying interests – Finding relationships between events 04/05/2010 - What's on this evening?
