If you have a question about this talk, please contact Dr Maria Ubiali.

I discuss the determination of the fragmentation functions (FFs) of light charged hadrons from a wide set of single-inclusive electron-positron annihilation cross section measurements. Specifically, I focus on the recent effort made by the NNPDF collaboration, using a methodology based on Monte Carlo sampling of experimental uncertainties and neural networks for parton parametrisation. I discuss the quality of the NNPDF determination, including its stability upon inclusion of higher-order corrections, and some of its implications in the description of the hadron spectra measured at the LHC .
