*Fragmentation Functions of Light Charged Hadrons*

I discuss the determination of the collinear fragmentation functions of 
light charged hadrons
from a wide set of single-inclusive electron-positron annihilation cross 
section measurements.
I focus on the recent effort made by the NNPDF collaboration, using a 
methodology based on
Monte Carlo sampling for the representation of data uncertaintiesand 
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 investigation of the spin
structure of the nucleon and in the description of the hadron spectra 
measured at colliders.
