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

There’s a lot of information out there…

A lot of information…
