The use of semantic information to improve IR is a long-standing goal. This paper presents a novel Document Expansion method based on a WordNet-based system to find related concepts and words. Expansion words are indexed separately, and when combined with the regular index, they improve the results in three datasets over a state-of-the-art IR engine. Considering that many IR systems are not robust in the sense that they need careful fine-tuning and optimization of their parameters, we explored some parameter settings. The results show that our method is specially effective for realistic, non-optimal settings, adding robustness to the IR engine. We also explored the effect of document length, and show that our method is specially successful with shorter documents.
