The Smooth Project

The Smooth project aims to optimise the performance of an Information Retrieval (IR) system by tuning the free parameters of the term frequency normalisation methods.

The setting of the term frequency normalisation parameter suffers from the query-dependent and collection-dependent problems, which significantly hurt the robustness of the retrieval performance. In this project, we proposed to provide a theoretical understanding of the term frequency normalisation, as well as solutions for the two problems.

Smooth is funded by the Leverhulme Trust, number F/00179/S.
