EventMedia: User Tasks and Challenges

EventMedia - Open Data Week - Marseille

Goals: Discover PAST, PRESENT and FUTURE events Live, relive and predict experiences through shared media Enhance search and recommendations mechanisms Support the decision making process

Challenges Semantization of Data (events, media, people) Reconciliation of sparse and highly heterogeneous data User-centric design: discovering, deciding and recommending Scalability, Caching and Optimization

Events through the web …


Event Directories

Media Platforms

Social Networks

Allows opportunistic/serendipitous discovery Limited social features and Information incompleteness (low coverage, weak decision)

Aids remembering and sharing past experiences Lack of consistent events descriptions

Attendance: popularity and friends' whereabouts, attendees’ opinions. Limited discovery mechanism: need to filter out relevant information.

Explore semantic connections to create better overviews of events
