Overview of the CLEF eHealth Evaluation Lab 2016

In this paper we provide an overview of the fourth edition of the CLEF eHealth evaluation lab. CLEF eHealth 2016 continues our evaluation resource building efforts around the easing and support of patients, their next-of-kins and clinical staff in understanding, accessing and authoring eHealth information in a multilingual setting. This year’s lab offered three tasks: Task 1 on handover information extraction related to Australian nursing shift changes, Task 2 on information extraction in French corpora, and Task 3 on multilingual patient-centred information retrieval considering query variations. In total 20 teams took part in these tasks (3 in Task 1, 7 in Task 2 and 10 in Task 3). Herein, we describe the resources created for these tasks, evaluation methodology adopted and provide a brief summary of participants to this year’s challenges and some results obtained. As in previous years, the organizers have made data and tools associated with the lab tasks available for future research
