Abstract

This paper performs a study on the pre-processing phase of the automated text classification problem. We use the linear Support Vector Machine paradigm applied to datasets written in the English and the European Portuguese languages – the Reuters and the Portuguese Attorney General’s Office datasets, respectively.

The study can be seen as a search, for the best document representation, in three different axes: the feature reduction (using linguistic information), the feature selection (using word frequencies) and the term weighting (using information retrieval measures).
