Dear colleagues,
good and bad news: More than 450 persons registered to RecSys 2015.
It is “sold out” according to initial “best case” plans!

However, if you still want to register, you should be aware of the fact that the registration package you will receive at the conference might not contain all the give-aways and contents that the participants who have registered by now will receive.

In case the plenary room will get too crowded we will provide a video stream to a neighboring lecture room.

Registration Options

RecSys 2015 offers several kinds of registration options: all-inclusive registration, conference-only (incl. tutorials and RecSys challenge), and registration for conference-only with a one-day workshop ticket.

All-inclusive registration includes the registration for the main conference, tutorials, both workshop days and the doctoral symposium, the reception, the conference dinner, and all lunches and coffee breaks.

Conference-only registration includes access to the main conference and the tutorials as well as the reception, the conference dinner, and lunches and coffee breaks on the three days of the main conference.

In addition to conference-only registration it is possible to register for a one-day workshop ticket including access to the workshops on that day (capacity limits may apply) as well as lunches and coffee breaks. You can choose one of the two workshop days (Saturday or Sunday) to complement your conference-only registration (it is not possible to register for workshops alone).

All prices are in € (Euro), and all times regarding registration are GMT+01:00 (Central European Time).
