Reproducibility has become increasingly important for many research areas, among those IR is not an exception and has started to be concerned with reproducibility and its impact on research results. This paper describes our second attempt to propose a lab on reproducibility named CENTRE, held during CLEF 2019. The aim of CENTRE is to run both a replicability and reproducibility challenge across all the major IR evaluation campaigns and to provide the IR community with a venue where previous research results can be explored and discussed. This paper reports the participant results and preliminary considerations on the second edition of CENTRE@CLEF 2019.
