If you plan to participate in an IberEval 2017 task, you must register via SEPLN 2017 desk.

In the registration form you will have to provide your contact information and the list of tasks for which you plan to participate. You may register for the SEPLN conference (which also includes free attendance to all SEPLN workshops, including IberEVAL), or just for IberEVAL (which gives you additional free access to all other SEPLN workshops, but not to the main conference).
