A constraint to automatically regulate document-length normalisation
Ronan Cummins, Colm O’Riordan · 2012

However, considerable parameter tuning is often needed to increase the effectiveness of the retrieval. Document length normalisation is one such aspect that requires tuning on a per-query and per-collection basis for many retrieval functions.
