Overview of the CLEF 2019 Personalised Information Retrieval Lab (PIR-CLEF 2019)

The Personalised Information Retrieval Lab (PIR-CLEF 2019) lab is an initiative aimed at both providing and critically analysing the evaluation of Personalization in Information Retrieval (PIR) applications. PIR-CLEF 2019 is the second edition of the Lab after the successful Pilot lab organised at CLEF 2017 and the first edition of the Lab at CLEF 2018. PIR-CLEF 2019 provided registered participants with two tracks: the Web Search Task and the Medical Search Task. The Web Search Task continues the activities introduced in the previous editions of the PIR-CLEF Lab, while the Medical Search Track focuses on personalisation within an ad hoc search task introduced in previous editions of the CLEF eHealth Lab.
